INTEGRATED CIRCUITS

DATA BOOK
Linear Integrated Circuits have achieved a level of maturity which now rivals that of
their digital counterparts. In all market categories and for a wide variety of applications
functions, linear ICs are serving the needs of equipment manufacturers to reduce cost
and improve equipment form, factor and reliability.
They've matured, too, from the standpoint of availability. The number of off-theshelf linear circuits and their varying capabilities makes them highly useful as building
blocks for system design. Moreover, the now-prevalent practice of second sourcing
assures competitive pricing and quantity delivery.
The Motorola Semiconductor Products Division has been in the forefront of linear IC
development since the inception of integrated circuit technology. This Linear Integrated
Circuit Data Book, therefore, contains data sheets for one of the largest selections of
linear ICs in the industry. Included are devices that were developed by the various
Motorola R&D groups, as well as an extensive second-source inventory of the most
popular circuits developed elsewhere.
For easy reference, the data sheets in this book are in alpha-numeric sequence, without
regard as to product category or applications. However, to provide the user with a qUick
overview of Motorola's complete line of standard linear ICs, a number of selector guides
separate the total line into market and/or functional divisions. This provides a quick
comparison of similar devices, spelling out the most Significant differences. Also included
are a cross-reference table of second-source devices and other product-related information.
The information in this book has been carefully checked and is believed to be reliable;
however, no responsibility is assumed for inaccuracies. Furthermore, this information
does not convey to the purchaser of microelectronic devices any license under the patent
rights of any manufacturer.

OPERATIONAL AMPLIFIERS
The operational amplifier has always been the most popular and versatile Linear Ie type. Op
amps have found wide usage in control circuitry, signal processing equipment, active filters for
communications systems, Modems, and many other types of equipment. With the addition of a
few externai components, this basic feedback type amplifier can be transformed into a multitude
of functions ranging from summing amplifiers and simple inverters to integrating amplifiers and
Sample and Hold circuits.
Motorola offers broad line of op amp types. Both proprietary and popular industry-standard
types are covered. The range of high precision to low cost plastic-packaged mUltiple op amps is
spanned by over 50 device types. Two representative devices are discussed here. An overview of
the entire line appears on pages 3-2 and 3-3.

High-8lew Op-Amp (MC1741S)

Applications where pulses are processed or
where distortion must be kept low under largesignal conditions are ideal candidates for the
MC1741S. Since the unit is a pin-for-pin replacement with all other specs identical to the conventional MC1741 , it is easy to update existing
designs to improve their performance.
Of particular significance is the 3.0 IJ,S settling
time (to 0.1%) of the new device. When combined
with an MC1508L digital-to-analog converter, a lowcost, two-package converter with a voltage-mode
output and total settling time to within ±1.0 least
significant bit of 4.0 IJ,S can be obtained.

It is not often that the advantages of the old
workhorse can be combined with the speed of
the thoroughbred. However, the MC1741 Sop-amp
has done just that; it has a II the familiar easyto-use features of the industry-standard MC1741
internally compensated op-amp. In addition, it
offers a guaranteed minimum slew rate of 10 V/lJ,s
with a typical slew rate of some 20 times greater
than the comparable figure for the conventional
MC1741. Power bandwidth has a'lso increased by a
factor of;m and is now specified at 150 kHz
minimlim.

logic to create electronics systems well suited for
critical low-drain, battery-powered equipment. The
MC1776 uses a maximum of only 120 /-IW at
±3.0 V and a programming current of 1.5 /-IA.
This assures long life from the battery.
To demonstrate the versitility of the MC1776,
all static and dynamic parameters are specified at
four combinations of power supply voltages and
programming current. Thus, the user is assured that
the op-amp will perform over this wide range of
operating conditions without having to guess how
changes in the programming conditions will affect
a particular operating parameter.
For operating flexibility and micropower consumption considerations, the MC1776 is the logical
choice.

Micro-Power, Programmable Op-Amp
(MC1776)
The ability to operate with minimal power consumption from a wide range of power supply
voltages is the salient feature of the MC1776 programmable op-amp. Whether two 1.2 V mercury
cells or supplies up to ±18 V are uti lized, the
performance features best suited for a particular
application can be selected. A single resistor or a
current source can be used to set all the quiescent
current levels for this circuit. Thus, the designer is
free to choose, for example, low bias and power
supply currents, or perhaps greater gain-bandwidth
and slew rate.
The MC1776 can be combined with McMOS

VOLTAGE REGULATORS
The sensitivity of semiconductor devices to voltage and temperature changes makes the voltage
regulator circuit an important integral part of many critical systems and subsystems. Today's
designer has considerable choice in integrated regulators, with a variety of characteristics,
capabilities, and prices. The integrated circuit voltage regulator offers ease of design, simplified
assembly and improved performances over discrete transistor designs. Motorola offers a series of Ie
voltage regulators with a variety of specifications, see pages 3-12 thru 3-14. Highlighted here are
two circuits that merit special attention.
The Simplest Voltage Regulator to Use
(MC7800)
The introduction of the three-terminal voltage
regulator marked a milestone in integrated circuit
development. Traditionally, IC voltage regulators
required numerous external components, and supplied only a few milliamperes without additional
current boosting transistors. They had to be pro·
grammed to the desired voltage with precision resistors, and could oscillate if proper circuit layout
considerations were ignored. The MC7800 Series
three·terminal fixed voltage regulators have eliminated these problems.
The new devices are housed in popular power
transistor packages which conven iently connect to
heatsin ks if necessary. They require only three
connections - Input, Output, and G ro undo External
components are required only if the regulator is
located an appreciable distance from the supply
filter capacitors or if current boosting is required
to supply greater than the 1.5 Amperes the devices
can provide. Ease of use and low cost make these
units ideal as on-card voltage regulators, or in almost any electronic system.
The MC7800 series devices are available in seven
popular fixed voltages. The last two numbers of the
part type indicate the nominal output voltage. Each
type features short-circuit protection, thermalshutdown, and safe-operating area compensation for
the internal series pass transistors. These techniques
combine to make the units extremely rugged.
With the arrival of the new MC7800 series
voltage regulators, a regulated power supply is
available at a minimum of cost and design effort for
almost any electronic device. By adding an additional transistor package, regulated voltage can
be available almost any place in a system.

• = Cin is requ ired if regulator is located an

appreciable distance from power supply
filter.
•• = Co is not needed for stability; however,
it does improve transient response.

The Negative Three-Terminal Regulator
Complements (MC7900)
The popular MC7800 series voltage regulators
described above are all well suited when a positive
voltage is required, but they are not intended for
negative supplies. For these applications the nega·
tive complements, series MC7900 were created.
These units are identical to the MC7800 series
devices except that the voltage and current are of
the opposite polarity. The negative regulators are
supplied in the same voltages available in the
positive series plus two additional voltages commonly used in MECL systems. These supplementary
voltages are -2.0 V and -5.2 V, making them well
suited for on-card regulation in high-speed logic
systems.
The same short-circuit, thermal over-load and
safe-operating area protection circuitry is employed
in the negative devices making them very rugged.
In addition, the devices have the same simplicity of
use as the positive MC7800 series devices. Three·
terminals, fixed·voltages, easy·heatsin king, and the
lack of required external components are features
that make the MC7900 series negative regulators
applicable to nearly any electronic system power
supply.

INTERFACE CIRCUITS
Interface circuits is the name applied to devices that operate with both linear signals and digital
logic levels. Most have both linear and digital properties. Examples of interface circuits are DIA
and AID converters, memory sense amplifiers, comparators, and line drivers and receivers.
The rapidly expanding fields of data communications and digital instrumentation make wide
use of these interface devices. Line drivers and receivers, for example, are used whenever data must
be transmitted over long distances in a computer or piece of peripheral equipment. Also, the
industry standard MC1488-89 devices provide the level translation between a Modem and a
computer terminal in accordance with the EIA RS-232C specifications. Likewise comparators are
used as voltage level detectors in control and instrumentation applications.
Motorola offers a broad line of interface circuits. Two of the newest interface devices are
discussed in this section while the complete lineup is outlined beginning on page 3-4.

high-speed capability inherent in the current mode
output of the MC1508and MCl506 01 A converters.
An 8-bit tracking AID system, for example, using a
5-MHz clock rate provides a normal conversion or
update every 0.2 to 1.0 j.lS, and a full-scale conversion time of 50 j.lS. Adding a second MC1507
and a "panic mode" circuit decreases the full-scale
conversion time to 14 j.lS.
By disabling the down counting function, the
tracking converter can be used as a peak-detecting
track and hold circuit. This system will store the
maximum value of an input waveform until it is
reset. Unlike traditional sample and hold circuits
uti lizing the charge on a capacitor, the MC1507
system will not suffer a voltage decay after a period
of time.
The versatile MC1507 has many additional applications bridging the analog and digital realms.
When combined with other building blocks, solutions to numerous analog-digital interface requirements can be economically provided.

The MC1507 is the third member of the
Motorola "building block" series aimed at bridging
the gap between the analog and digital worlds. This
device is particularly useful when combined with
either the MC1508 or MC1506 monolithic Digitalto-Analog (D/A) converters to implement either
Tracking or Successive Approximation Analog-toDigital (AID) Converter designs.
The MC1507 consists of a high-slew-rate op-amp
used asan input buffer and a dual-comparator which
provides two adjustable, but symmetrical, thresholds. The comparator is used in tracking AID
systems to command a counter chain to increment
either up or down. The comparator section is also
applicable to "dead-band" or "window" comparator
designs where indication is given if an input voltage is greater than or less than a specified voltage
range.
The tracking AID converter, for which the
MC1507 is primarily intended, makes use of the

In addition to their usage to transmit data Within large computer systems, the quad receivers are
well suited for use as sense amplifiers with "1103"
type MOS memory systems. The quad configuration
results in a considerable package savings over existing devices commonly used in this type of
application.

ENTERTAINMENT CIRCUITS
The high-volume, low-cost, and highly specialized requirements of the electronic components
for consumer entertainment equipment match the capabilities of today's linear ICs. A great
variety of the necessary functional blocks for television, stereo phonographs, and radio receivers is
now available in low-cost plastic-packaged ICs. The need for improved performance and increased
reliability and, at the same time, for a lower selling price, is met by state-of-the-art monolithic
circuits.
Motorola's traditional leadership in plastic transistors for the customer electronics industry is
being extended with a complete lineup of low-cost ICs for those functions which can best be
accomplished with monolithic integrated circuits. Both original innovative designs and popular
second-source devices which have been well accepted by the industry are included in this diverse
family of products. Some typical examples are highlighted here.

For Te Ie vi si 0 n

alone, Motorola offers more than 20 different types of ICs to give the
designer a wide choice of performance levels and partitioning approaches. To aid in the parade
toward fully solid-state sets, Motorola offers ICs for the video IF amplifier and detector, AF.T,
chroma processor and detector, deflection, audio stages, and a combination device which supplies
AGC, sync separator and noise-suppression circuitry. Often these I Cs permit circuit complexity and
performance which would not be technically and economically practical with discrete components.
A selector guide to ICs for use in television sets is provided on page 3-16. Several new TV ICs
are previewed on page 4-6.

For Automotive . ..

In response to consumer demand and government legislation, the automotive industry is undergoing a major engineering evolution Electronics will be used to perform many of the new complex
functions required for the modem automobile. Two approaches are being accepted for applying
ICs to automotive electronics: custom and building block. Because of the large volume potential,
almost all programs can be expected to end with a specialized custom circuit. However, in the
interim, while the systems are being defined and refined, the Motorola building block approach has
received wide acceptance.

INTERFACE CIRCUITS
Interface circuits fit in the gray area between the
linear and digital realms. Usually these IC's perform the
necessary translation between an analog signal input and
the required digital logic levels or vice versa. To aid in

selection, the devices have been divided into five main
categories: Sense Amplifiers, Drivers, D/A Converters,
Receivers, and Comparators.

INDUSTRIAL PRODUCTS
Linear ICs have traditionally found wide application in the diverse Industrial market place.
Numerous types of op amps, voltage regulators, analog multipliers and timers fill important roles in
process control, instrumentation, and signal processing functions. The devices previewed below
complement an already substantial lineup of Motorola Industrial products.

I lers

The MC3570G is intended for applications requiring optimum speed. It has a typical unity gain
slew rate of 100 V/jJ.s with a 30 pF load. Power
bandwidth is an impressive 1.5 MHz, and unity
gain crossover frequency is at 15 MHz. The units
are internally compensated for unity gain stability
with 300 of phase margin.
High-speed signal processing, AID and D/A conversion, and high-frequency instrumentation are
just three examples of areas which can make use of
this high-speed monolithic operational amplifier.

The MC3503/3403 is a quad, true differentialinput operational amplifier designed for either
single or split power supply (±15 V) operation.
The four internally-compensated amplifiers within a package draw a total supply current of only
2.5 rnA maximum - independent of supply voltages. When the device is operated with split supplies, most specifications equal or exceed comparable parameters for the popular MC1741.

LINEAR-DIGITAL INTERFACE PRODUCTS
The need to span the gap between analog information and digital processing is becoming increasingly prevalent. In fact, a whole family of linear (analog)/digital interface devices has arisen
in the past few years. This category is highlighted at Motorola by a number of new monolithic
D/A and A/Dconverters. Several of the newest elements in this rapidly expanding field are the
topics of the fol/owing paragraphs.

MC3537 Hex Unified Bus Receiver
MC3538 Quad Unified Bus Transceiver

MC1505 Digital Voltmeter Subsystem
(AID Converter)

Where bus-organized data transmission systems
are employed, the MC3537 and MC3538 can be
efficiently utilized to solve interface problems. The
MC3537 contains six bus receivers, while the
MC3538 contains four drivers and four receivers
with each driver-receiver pair sharing common
input-output pins.
Both types incorporate hysteresis in the receivers to permit excellent noise immunity, and are
optimized for bus rise and fall times less than
10,us.

The MC1505 is the analog front-end portion of
either a 4~ or 3~ digit DVM. It is designed for use
with the MC14435 McMOS logic subsystem to produce the complete 3~ digit DVM function (ex·
c1uding display). The MC1505 can also be used
alone as a general purpose AID converter.
The MC1505 uses the proven dual ramp AID
conversion technique. The subsystem consists of
an on-chip voltage reference, a pair of voltagel
current converters, an integrator, a current switch,
a comparator, and associated control and calibration circuitry. The device requires only one capacitor and two potentiometers for operation.

FEATURES:
•
•

Hysteresis of 1.0 V provided in receivers
High receiver noise immunity: 2.0 V typical

FEATURES:

MC3460 Quad NMOS Memory Dnvers
These quad drivers provide the interface between MTTL logic and NMOS memories. The
MC3459 is a low-voltage driver for address lines
while the MC3460 is a high-voltage device for
driving the clock lines. The devices will drive 350
pF loads with propagation delay times of 25 ns and
35 ns respectively.
The high-voltage version uses a multiplexed
pullup circuit to reduce power consumption.

Both of these comparators feature 20 ns response time and a strobe input common to the four
units. However, the MC3430-31 have active pullup
outputs and a three-state strobe, while the MC343233 are equipped with open-collector outputs.
In applications requiring numerous comparators,
such as the sensing of 11 03-type MOS memories, the
greater package density permitted by the quad
configuration results in considerable saving in
circuit board space.

The MC3463 is a quad line driver with MECL
10,000 compatible inputs. The device switches a
12 mA current sink between each of the two outputs per channel in response to the input logic
condition. A pair of inhibit inputs is provided with
each inhibit common to two of the channels.
Typical propagation delay time is less than 3.0
ns from the logic inputs and 5.0 ns from the inhibit inputs.

The MC3462 is a quad MECL 10,000 compatible line receiver designed for use with the
MC3463 line driver. The MC3462 has a strobe
input common to all four channels, sensitivity of

LINEAR INTEGRATED CIRCUIT

CHIPS
Most of the linear integrated circuit devices in this Data Book are available in chip form. Many
are offered in several options - such as conventional (face up bonding), beam lead, and flip-chip
versions. Motorola offers many standard linear chips from warehouse stock either directly from the
factory or through franchised distributors. In addition, custom linear IC chips may be designed and
produced to meet a specific need.
Specific information on chip processing, testing, and handling can be obtained in the Semiconductor Chips Data Book.

Electrical limits for stocked linear IC chips in conventional, beam lead, and flip-chip formats
are included on data sheets in this book. (See page 6-4 for listing of stocked chips.)

LINEAR CHIP FORMATS

Conventional Chips encompass by far the greatest number
of available linear Ie chips. These silicon chips use gold backside metalization for easy eutectic bonding to the metalized
area of hybrid assemblies. The interconnecting metalization
and bonding pad areas are formed from evaporated aluminum.
Either gold or aluminum wire may be employed for connection
between on-chip bonding pads and the external circuit.

Beam-Lead Chips are distinguished from conventional chips
by the presence of cantilevered beams used to interconnect
the chip circuit element with the substrate circuit bonding
pads. In production, a complex integrated circuit chip with a
large number of interconnecting beams can be connected to
the substrate, forming all necessary interconnections in a single
operation, using wobble·bonding techniques. I n addition, the
entire surface of a beam-lead chip, except the beams, is covered
with a passivating layer of silicon nitride that is as effective as a
hermetically sealed package in protecting the circuit against
contamination.

Flip-Chips, like beam-lead chips, can be mounted to a
hybrid substrate in a single operation.
In the case of flip-chips, connection to the substrate bonding pads is made by means of raised "solder bumps" that pro·
trude above the chip surface at the integrated-circuit bonding
pads. The devices are mounted to the substrate metalization
areas circuit side down by means of conventional ref low solder
techniques.

LINEAR INTEGRATED CIRCUITS

Under the M I L-M-3851 0 program, Motorola linear integrated circuits may be procured to the specifications of M I L-M-3851 0 and to four levels of processing which
meet the screening requirements of MI L-STD-883.
This comprehensive program is structured to provide an environment in which
proven methods of manufacturing, quality assurance, monitoring, screening, and
testing can produce the most reliable product on the market. Because it is a
"standard" hi-rei program, it is designed to facilitate delivery and to minimize specification preparation time.
Motorola has qual ified a variety of linear integrated circu its under the MIL -M-3851 0
program. These device types are available (more will be available during 1974) as
JAN-QUALI F I ED product. These devices have specific detailed specifications called
"slash specs".
In addition, nearly all full-temperature-range linear device types are available as
JAN-PROCESSED product with the same MIL-M-38510 processing sequences as
Qualified product, but with other requirements as listed on page 7-5.
Further details and specific processing information can be obtained from your
Motorola representative.
Note that this program supercedes the Checkmate high-reliability processing
program.

MIL-M-38510 JAN-QUALIFIED PRODUCT

JAN-QUALIFIED devices are built to the stringent specifications outlined by the Defense
Electronics Supply Center (DESC). These devices must be manufactured in a government-approved
facility and are screened to electrical limits outlined in government documents referred to as "slash
sheets". These specifications may differ from standard Motorola electrical limits as stated in the
device data sheets.

MIL-M-38510 JAN-PROCESSED PRODUCT

JAN-PROCESSED product is intended to assure the same high reliability manufacturing
sequences as JAN-Qualified devices, but without the requirement for government source
inspection_ JAN-Processed devices are available tested to either "slash-sheet" limits or to
Motorola data sheet electrical limits. This part of the program replaces the Motorola Checkmate
hi-reI program and encompasses al/ military-temperature-range linear ICs rather than just those
covered under existing "slash sheets".

MAJOR REQUIREMENTS OF
JAN-PROCESSED PRODUCT
1. No G.S.I. provided.

HOW TO ORDER
MIL-M-38510 JAN-PROCESSED
PRODUCT

2. Government-approved facility not required.

Motorola Part No.

3. Product supplied with MIL-M-38510 electrical
specifications will be designated by an "M" suffix.
4. Product supplied with Motorola standard data
sheet electrical specifications will be designated by
an "5" suffix.

The part number for ordering a JAN-Processed
device consists of the following elements:
MCXXXX

The MCXXXX designates the Motorola source
device type.

6. Inventories will be maintained prior to burn-in and
final electrical tests.

(2)

B - This is a single letter and specifies the
device class per MIL-M-38510 for classes A,
B, and C. Class 0 is an added Motorola
JAN-Processing class and is the same as the
MIL-M-38510 Class B except for the differences
shown in the Screening Procedures table.

SCREENING PROCEDURES
(To MIL-STO-883 Requirements)
This program establishes screening procedures for total lot screening of integrated
circuits to assist in achieving levels of quality
and reliability commensurate with the intended
application. In recognition of the fact that the
levei of screening has a direct impact on the
cost of the product as well as its quality and
reliability, four standard levels of screening are
provided to coincide with four device classes or
levels of product assurance.

Flexibility is provided in the choice of con·
ditions and stress levels to provide screens,
tailored to a particular product or application.
Selection of a level better than that required for
the specific product and application will, of
course, result in unnecessary expense. A level
less than that required will result in an unwarranted risk that reliability and other requirements will not be met. For general hi·rel
applications, the Class B screening level should
be considered.

DESIGN CONSIDERATIONS
3. Frequency Response

The MCI306P provides the designer with a means to control
preamplifier goin, power amplifier goin, input impedance, and

The low frequency response is controlled bV the cumulative
effect of the series coupling capacitors Cl, C2, and C3. High·
frequency response can be determined bV the faedback capacitor,

1. Gain
The Preamplifier Stage Voltage Gain is:

and is limited onlv bV the open·loop goin (270 V IV). For good
preamplifier de stabilitv Rf should be no larger than l.o-megohm.
The Power Amplifier Voltago Gain is controlled in a similar
manner where:

circuit.

The increase of battery resistance with age has two undesirable
effects on circuit performance. One effect is the increaSing of
amplifier distortion at low Signal levels. This is readilv corrected bV
increasing the size of the filter capacitor placed across the battery
(as shown in Figure B; a 300-IlF filter capacitor gives distortions
at low·tonal levels that are comparable to the "stiff" suppIV). The
second effect of supplV impedance is a lowering of power output
capability for steady signals. This condition is not correctable, but

Recommended values of Rp range from 500-ohms to 3.3·k
ohms. The low end is limited primarily by

= Rf

Additional high frequency roll·off and noise reduction can be
achieved by placing a capacitor from the center point of Rp to
ground as shown in Figure 10.
capacitor C4 and the RC network shown in dotted lines mav
be naeded to prevent high frequency parasitic oscillations. The R F
choke, shown in series with the output, and capacitor C6 are used
to prevent the high·frequency components in a large-signal cl ippad
audio output waveform from radiating into the RF or IF sections
of a radio (Figure 10).

the upper end is limited due to the voltage drive capabilities of the
pre-amplifier. (A resistor can be added in the de feedback loop,
from pin 6 to ground, to increase this drive); The Overall Voltage

5. Application Examples: (1) The audio section of the AM·FM
radio (Figure 1) is adjusted for a preamplifier gain of 100 with an
input impedance of lO-k ohms. The power amplifier gain is set at
la, which gives an overall voltage gain of 1000. The bandwidth
has been set at 10·kHz. (2). The phono amplifier (Figure 2) is designed for a preamplifier goin of unity and a power amplifier goin
of 10. The input impedance is l.o-megohm. An adjustable treble
control is provided within the feedback loop.

CIRCUIT OPERATION
the regenerated 38-kHz signal. The regenerated 38-kHz
Signal is fed to the stereo decoder via an internal switch,
which closes when a sufficiently large 19 kHz pilot tone
is received.
The 19-kHz signal returned to the 38-kHz regeneration
loop modulator is in quadrature with the 19-kHz pilot
tone when the loop is locked. With the third divider
state appropriately connected, a 19-kHz signal in phase
with the pilot tone is generated. This is multiplied with
the incoming signal in the stereo switch modulator
yielding a dc component proportional to the pilot tone
amplitude. This component after filtering is applied to
the trigger circuit which activates both the stereo switch
and an indicator lamp.

Figure 13, on the previous page, shows the system
block diagram. The upper line, comprising the 38-kHz
regeneration loop operates as follows: the 'internal oscillator running at 76-kHz and feeding through two
divider stages returns a 19-kHz signal to the input modulator. There the returned signal is multi pi ied with the
incoming signal so that when a 19-kHz pilot tone is
received a dc component is produced. The dc component
is extracted by the low pass filter and used to control
the frequency of the internal oscillator which consequently becomes phase-locked to the pilot tone_ With
the oscillator phase-locked to tre pilot the 38-kHz output from the first divider is in the correct phase for decoding a stereo signal. The decoder is essentially another
modulator in which the incoming signal is multiplied by

detector; time constant is C4 x 53
kilohms ±30%, maximum dc voltage
appearing across C4 is 0.25 V (pin 8

The signal voltage across C4 is negligible.

C5

See Phase Compensation section.

R3, C6. C8

Phase-locked loop filter components;
the following network is recommended:

These values give ±3.5% typical capture
range. Capture range may be increased
by reducing C7 and increasing R4, R5
proportionally but at the cost of increasing beat-note distortion (due to
oscillator-phase jitter) at high-signal
levels. See Figure 12.
Stereo Lamp

Nominal rating up to 75 mA at 12 V;
the circuit includes surge limiting which
restricts cold-lamp current to approximately 250 mAo

19-kHz Output

A buffer output providing a 3.0-Vpk
square wave at 19 kHz is available at
pin 10. A frequency counter may be
connected to this point to measure the
oscillator free-running frequency for
alignment. See Alignment section.

External Monaural/Stereo Switching
If it is desired to maintain the circuit in monaural
mode, the following procedure must be followed. First,
the stereo switch must be disabled to prevent false lamp
triggering. This can be accomplished by connecting pin 8
negative or pin 9 positive by 0.3 volt. Pin 8 may be
grounded directly if desired. Note that the voltage across
C4 increases to approximately 2 volts with pin 9 positive
when pin 8 is grounded.
Second, the 76-kHz oscillator must be killed to
prevent interference when on AM_ This can be accomplished by connecting pin 14 to ground via a current
limiting resistor (3.3 kilohms is recommended).

CB

When less performance is required a
simpler network consisting of R3 = 100
ohms and C6 = 0.25/.1F may be used

Phase Compensation/IF Roll-off Compensation
Phase-shifts in the circuit cause the regenerated 38kHz sub-carrier to lead the original 38 kHz by approximately 20. The coupling capacitor C5 generates an

APPLICATIONS INFORMATION (continued)
additional lead of 3.50 (for C5 = 0.05I1F) giving a total
lead of 5.50.
The circuit is so designed that phase lag may be
generated by adding a capacitor from pin 3 to ground.
The source resistance at this point is 500 ohms. A
capacitance of 820 pF compensates the 5.50 phase lead:
increase above this value causes the regenerated subcarrier to lag the original. However, a 5.5 0 phase error
if left noncompensated will not degrade separation
appreciably.
Note that these phase shifts occur within the phaselocked loop and affect only the regenerated 38-kHz
sub·carrier: the circuit causes no significant phase or
amplitude variation in the actual stereo signal prior to
decoding.
Most I F amplifiers have a frequency response that
limits separation to a value significantly lower than the
capability of the MC1310. For example, if the response
produces a 1-dB roll-off at 38 kHz, the separation will be
limited to about 32 dB. This error can be compensated
by using an RC lead network as shown in Figure 14.
The exact values will be determined by the I F amplifier
design. However, the values shown in Figure 14 are
suitable for use with the MC1357 and MC1375 IF
ampl ifiers.

Alignment Procedure
The optimum alignment procedure, with no input
signal applied, is to adjust R5 until 19.00 kHz is read at
pin lOon the frequency counter.
Another procedure requiring no equipment, other
than the receiver itself, will result in separation of
within a few dB of optimum. This latter method is
merely to tune the receiver to a stereo broadcast and
adjust R5 until the pilot lamp turns "on". To find the
center of the lock-in range, rotate the potentiometer
back and forth until the center of the lamp "on" range
is found. This completes the alignment.

FIGURE 14 - IF COMPENSATION NETWORK

Alternate Timing Network
The alternate timing network shown, incorporating a
trimmer capacitor rather than a potentiometer, may be
used if desired. Again, to provide correct temperature
compensation, the temperature coefficient of the timing
network must be approximately -300 PPM.

FIGURE 16

Voltage Control Oscillator Compensation
Pin 14

Figure 10 illustrates noncompensated Oscillator Drift
versus temperature. The recommended TC of the R4, R5,
C7 combination is -300 PPM. This will hold the
oscillator drift to approximately ±1% over a temperature
range of -40 to +850 C. Allowing ±2% for aging of the
timing components acceptable performance is still ob·
tained.
Lamp Sensitivity
It may be desirable in some cases, to change the lamp
sensitivity due to differing signal levels produced by
various FM detectors. The lamp sensitivity can be
changed by making use of the external circuit shown.
Typical sensitivities versus potentiometer rotation are
also shown in Figure 15.

Maximum Load Resistance
The curve shown gives absolute maximum load resistance values versus supply voltage used for full-signal
handling capability. With desired load resistance choose
C2, C3 capacitors to provide standard 7511s de-emphasis.

The decoding process is shown schematically in Figure 4. The
MC1312P/MC1313P circuits that perform this function consists of
two preamplifiers which are fed with left total, LT. and right total,
RT. signals. The preamplifiers each feed two all-pass* networks
that are used to generate two LT signals in quadrature and two
RT signals in quadrature. The four signals are matrixed to yield
left-front, left-back, right-front, and right-back signals (LF', LB',
RF', RB'I.
The all-pass networks are of the Wein bridge form with the
resistive arms realized in the integrated circuit and the RC arms
formed by 8)(ternal components. The values shown in Figure 1
are for a l00-Hz to 100kHz bandwidth and a phase ripple of ±8.5°
on a 90" phase difference_
It is generally desirable to enhance center-front to center-back
separation. This is accomplished by connecting a resistor between
pins 2 and 11 (front outputs) and 3 resistor between pins 3 and
14 (back outputsl. For a 10% front channel blending t and a 40%
back channel blending t , 47 kilohms between pins 2 and 11 and

sa broadcast.

7.5 kilohms between pins 3 and 14 is required and results in the

CIRCUIT OPERATION
Capacitors C1, C2 and C3 provide filtering of carrier harmonics
from the detected color difference signals. This increases the available swing before clipping for the color difference signal, and reduces the high frequency components yvhich must pass through the
emitter followers (01, 02, 03) into the video output stages. Since
high capacitance (>100 pF) is characteristic of the input impedance
of a video output stage, the transistor emitter followers must operate at a high quiescent current (>5 mA) in order to pass large high
frequency components without distortion. The filtering reduces
the quiescent current required in the emitter followers and thus
reduces dissipation in the integrated circuit.

A double sideband suppressed carrier chroma signal flows between
the bases of the two differential pairs, 015 and 016, 017 and 018.
A reference signal of approximately 1 Vp-p amplitude having the
same frequency as the suppressed chroma carrier with an appro~
priate phase relationship is supplied between the bases of the upper
differential pairs 05 and 06, 07 and as, 09 and 010, 011 and
012. The upper pairs are switched between full conduction and
zero conduction at the carrier frequency rate. The collectors of
the upper pairs are cross-coupled so that "doubly balanced" or
"full-wave" synchronous detected chroma signals are obtained.
Both positive and negative phases of the detected signal are available at opposite collector pairs.

TV-IF Amplifier Information
A very compact high performance I F amplifier constructed as shown
in Figure 11 minimizes the number of overall components and alignment adjustments. It can be readily combined with normal tuners
and input tuning-trapping circuitry to provide the performance de-

manded of high qual ity receivers. Th is configu ration wi II provide
approKimately 84 dB voltage gain and can accomodate the usual
low impedance input network or, if desired, can take advantage of
an impedance step·up from tuner to MC1350P input (Zin ~7.0 kil·
ohms). The burden of selectivity, formerly found between the third
I F and detector, must now be placed at the interstage. Tho
nominal 3 volt peak·to·peak output can be varied from 0 to 7.0 V
with excellent linearity and freedom from spurious output products.

Primary Winding: 8 turns of AWG #26 close wound, CT
Secondary Winding: 6 turns of AWG #26 close wound, CT
Core: Arnold Typa·TH slugs or equiv.

specific features and information on systems design with this device
are given below:
1. The device provides excellent linearity of output versus input,
asshown in Figure 6. This graph also shows that video peak·to·peak
amplitude (ac) does not change with supply voltage variation.
(Slopes are parallel. Visualize a given variation of input CW and use
the figure as a transfer function.)
2. The de output level does change linearly with supply voltage.
This can be accommodated by regulating the supply or by referencing the subsequent video amplifier to the same power supply.
3. The choice of a for the tuned circuit of pins 2 and 3 is not critical. The higher the Q, the better the reiection of 920 kHz products
but the more critical the tuning accuracy required. Values of a
from 20 to 50 are recommended. (Note the internal resistance.)
4. A video output with positive-going sync is available at pin 5 if
required. This signal has a higher output impedance than pin 4 so
it must be handled with greater care, If not used, pin 5 may be
connected directly to the supply voltage (pin 6),
5. An AFT output (pin 1) provides 350 mV of clipped carrier output, sufficient voltage to drive an AFT ratio detector, with only one
additional stage.

Alignment is most easily accomplished with an AM generator, set
at a carrier frequency of 45.75 MHz, modulated with a video frequency sweep. This provides the proper realistic conditions necessary to operate the low-level detector (LLD). The detector tank is
first adiusted for maximum detected de (with a CW input), next,
the video sweep modulation is applied and the interstage and input
circuits aligned, step by step, as in a standard IF amplifier.
Note: A normal IF sweep generator, essentially an FM generator,
will not serve properly without modification. The LLD tank attempts to "follow" the sweep input frequency, and results in variations of switching amplitude in the detector. Hence, the apparent
overall response becomes modified by the response of the LLD tank,
which a real signal doesn't do.
This effect can be prevented by resistively adding a 45.75 MHz CW
signal to the output of the sweep generator approximately 3 dB
greater than the sweep amplitude.

MC1330P General Information
The MCI330P offers the designer a new approach to an old problem. Now linear detection can be performed at much lower power
signal levels than possible with a detector diode.
Offering a number of distinct advantages, its easy implementation
should meet with ready acceptance for television designs. Some

The typical response for a quarter-track 13% in/sl tape·head is
3.0 dB down at 1770 Hz. Therefore, the high·corner Irequency
If21 of the record amplifier should be at the same frequency. Using
equation 4 the value of C3 is calculated to be 1.0 "F. Resistor
Rl is not needed to roll·olf the high·frequency gain at frequencies
above 20 kHz since. the limited open·loop gain of the MC1339P
accomplishes the same thing. The parallel LC circuit at the ampli·
fier output is used to trap the bias oscillator signal and is tuned to
that frequency.

Most of the circuits in the applications section can be built on
this printed circuit board layout. Printed circuit board design is
not particularly critical with the MC1339P. However, usual layout
practices such as keeping the input and output lines separated and
providing maximum ground plane area should be used. The layout
shown is for Figure 5 but it can easily be modified without any
problem for the other application circuits given.

and for low frequencies, (as shown in the test circuits). This is
due to the dual function of the input amplifier. If replacing MC1350P take precaution not to ground pin 3, (not used in the
MC1350P). Due to the significantly higher gain of the MC1349P,
extra care in layout should be exercised.

GENERAL INFORMATION
The MC1349P is an improved version of the MC1350P. Featuring higher gain, a lower noise figure, and greater AGe range;
in addition, an emitter of the input amplifier is available for by·
passing. This provides a low input impedance with good gain,
useful for untuned input configurations.
Both input and output I F amplifier sections are gain-controlled
in the MC1349P, with the input amplifier also serving as an AGC
amplifier for the output section. During the initial part of AGe
gain reduction, the gain of the input amplifier decreases only a
few dB while the output section decreases 15 dB; further AGC
acts upon the input section. Although the gain reduction curve
was taken with 5.1 kilohms at pin 5. higher series resistance can
be used to reduce the voltage and temperature sensitivity of the
AGe. Pin 5 currents are shown on the AGe curve, see Figure 10.
I n use, it is important to bypass pin 2, both for I F frequencies

NOTE 1: The references to bypasses at pin 3 do not give specific
values (C4, see Figures 1 and 4). In all cases, measurements were taken with a bypass at a standard value as
near as possible to series resonance. The values are dependent on test frequency and circuit layout. FuliV
bypassing pin 3 reduces the input signal handling capability before distortion from over 100 mVIRMS) to
approximately 25 mV(RMS). C4 ~ 0.002 IlF at f ~ 45
MHz is a typical value for printed circuit applications.

GENERAL OPERATING INFORMATION

FIGURE 4 - CIRCUIT SCHEMATIC
AGe AMPLIFIER SECTION

The input amplifiers (01 and 02) operate at constant emitter
currents so thet input impedance remains independent of AGC
action. Input signals may be applied single-anded or differentially
(for ac) with identical results. Tarminals 4 and 6 may ba driven
from a transformer, but a dc path from either terminal to ground
is not permitted.
AGC action occurs as a result of an Incraasing voltage on the
base of 04 and as causing thasa transistors to conduct more
heavily thereby shunting signal current from the interstage amplifiers 03 and 06. The output amplifiers ara supplied from an active
current source to maintain constant quiescent bias thereby holding
output admittance nearly constant. Coli actor voltage for the output amplifier must be supplied through a center-tapped tuning
coli to Pins 1 and S. The 12-volt supply (V+) at Pin 2 may be used
for this purpose, but output admittance remains more nearly constant if a separate 15-volt supply (V++) is used, because the base
voltage on the output amplifier varias with AGC bias.

FIGURE 3 - POWER GAIN, AGC AND NOISE TEST CIRCUIT

Ve, is maintained across the external capacitor, C2, for a particular
video level and dc reference setting. The voltage VC. is the result
of the charge delivered through 01 and the charge drained by 01.
The charge delivered occurs during the time of the gating pulse,
and its magnitude is determined by the amplitude of the video
signal relative to the dc reference level. The voltage Vc is delivered
via the I F-AGC amplifier and applied to the variable gain stage of
the IF signal amplifier and is also applied to the RF-AGC amplifier,
where it is compared to the fixed RF-AGC delay voltage reference
by the differential amplifier, 02 and 03. The following stages
amplify the output signal of either Q2 for MC1352, or 03 for
MC1353 and shift the dc levels causing the RF·AGC voltage to
vary (positive-going for MC1352 or negative-going for MC1353l.

GENERAL OPERATING INFORMATION

The input amplifiers (Q4 and 05) operate at constant emitter
currents so that input impedance remains independent of AGC
action. Input signals may be applied single-ended or differentially
(for ac). Terminals 1 and 2 may be driven from a transformer, but
a de path from either terminal to ground is not permitted.
AGC action occurs as a result of an increaSing voltage on the
base of 06 and Q7 causing those transistors to conduct more heavily
thereby shunting Signal current from the interstage amplifiers 08
and 09. The output amplifiers are fed from an active current
source to maintain constant quiescent bias thereby holding output
admittance nearly constant.

Each device, MC1352 and MC1353. consists of an AGe section
and an I F signal amplifier (Figure 2) subdivided into different func-

tions as indicated by the illustration.
A gating pulse, a reference level, and a composite video signal
are required for proper operation of the AGe section. Either
positive or negative-going video may be used; necessary connections
and signal levels are shown in Figure 1. The essential difference is
that the video is fed into Pin 10 and the AGe reference level is
applied to Pin 6 for a video signal with positive-going sync while
the input connections are reversed for negative*going sync.
The action of the gating section is such that the proper voltage,

FIGURE 5 - TYPICAL AGC APPLICATION CHART

NOTES:
1. The 12-V supply must have a low ac impedance to prevent lowfrequency instability in the RF*AGC loop. This can be achieved
by a 12*V zener diode and a large decoupling capacitor. (5 jJF).
2. Choices of C1, C2 and C3 depend somewhat on the set designers'
preference concerning AGC stability versus AGC recovery speed.
Typical values are C1 ~ 0.11lF, C2 ~ 0.251lF, C3" 10 JiF.
3. To set a fixed IF-AGC operating point (e.g., for receiver alignment) connect a 22 kH resistor from pin 9 to pin 11 to give minimum gain, then bias pin 14 to give the correct operating point
using a 200 kn variable resistor to ground,

4. Although the unit will normally be operating with a very high
power gain, the pin configuration has been carefully chosen so
that shielding between input and output terminals will not
normally be necessary even when a standard socket is used.

CIRCUIT DESCRIPTION
The MC1370 monolithic circuit provides the sub-carrier re-

generation function necessary for a color television receiver to
decode the NTSC color signal. An internal gate extracts the burst
voltage and this signal is processed in two-phase detectors, the
quadrature detector controls the phase of the local oscillator and
the in-phase detector is used to provide a noise immune ACe and

color killer control voltage. A shunt regulator sets the bias voltages
and ensures stable operation when there are supply voltage varia-

tions.
The basic 3.579545 MHz oscillator consists of the differential
amplifier (Q1 and Q2) with a feed-back loop through a quartz crystal
operating in series resonance from 02 collector to the non inverting
input of the amplifier represented by 01 base. To control the
oscillator frequency the phase shift of the feed-back path is made
variable by the addition of 05 and 06. A capacitor connected
between pins 7 and 8, together with the collector loads, forms a
RC phase-shift network. Consequently, the oscillator signal appearing at pin 7 can be moved in phase over a 45° range by the differential bias applied to 05 and 06 bases. The crystal between pins
7 and 6 completes the feed-back loop. The automatic phase control
to the upper differential pairs of the (05, 061 oscillator is through
the buffer stages Q7 and 08_ The oscillator amplifier is buffered
by 03 and Q4. Output from the oscillator is obtained from the
collector of 1 and is essentially a square wave of 9 rnA peak-topeak with a frequency range of several hundred Hertz.
The control voltage for 05 and 06 is obtained from the phase
detector 09 and alD. As 01 is the current source for this pair,
the voltages appearing at pins 11 and 12 will correspond to the
phase difference between the oscillator current and the burst signal
applied to pin 13. The loop characteristics are controlled in part

a

by a' filter connected between pins 11 and 12. This is usually a
double-time constant network to yield good pull-in times with a
low-noise bandwidth.
To ensure that the quadrature phase detector functions only
during the burst portion of the incoming chroma signal, the detector is gated into conduction by a pulse from the line flyback transformer - applied at pin 4. This has the additional advantage that
the average current in the phase detector has been reduced by the
gate duty factor thus relaxing the input offset stability requirements
of the differential pair and enabling them to be used with high dc
gain.
For the ACC control voltage and color-killer function a similar
phase detector, 015 and 016, is used. However, the chroma signal
input to pin 14 is phase shifted externally by' gOO with respect to
pin 13. As a result, 015 and 016 is an in-phase detector and the
control voltage at pins 15 and 16 will be proportional to the amplitude of the burst. Thus filtering of pins 15 and 16 provides the
control voltage for the gain control stage in the chroma J F and an
indication of the incoming signal strength for the color-killer circuit.
When the phase detectors are not gated "on" by a positive
pulse at pin 4, the bases of 013 and Q14 are held above the bases
of the phase detector inputs. Therefore, between gate pulses, all
the current" from the oscillator output 01 passes through Q13 and
014 to pins 2 and 3. When a phase·shift network is connected
between pins 2 and 3, the phase of the oscillator drive to the demodulators can be controlled by changing the relative conduction
of 013 and Q14 with a bias on pin 1. As a result the oscillator output is controlled in phase providing a dc hue control and is gated
"off" during the burst period, negating the need for burst blanking
in the chroma IF amplifier.

CIRCUIT DESCRIPTION
The MC1371

is a monolithic wide-band amplifier circuit that

functions as the basic control and color signal amplification stages

of a color television receiver. The first stage contains the gain
control function of the ACe loop and the second stage performs
the de manual gain control function. Also included is a Schmitt
trigger circuit providing effective color-killer action during mono-

chrome transmissions.
Q1 is a current source modulated by the input signal applied
at pin 2. The current in Q 1 is divided between the differential
pair (02 and 03) in a ratio determined by the ACC voltage applied
through the buffer stages, 04 and 05. Pin 14 is usually offset
with respect to pin 1 by a resistor connected to ground so that at
low·signal levels most of the signal current is taken by 03 and
passed to the load resistor R 5 (the input stage appears as a cascode
amplifier to the signal with the intrinsic ac stability of that configurationL The amplified signai' is then buffered at pin 6 by the
emitter follower stage 06 which is protected from accidental
grounding at the output by the current limiter 07.
At strong signals when the amplitude of the burst is high,
the ACe voltages at pins 1 and ,14 divert most of the signal current
from 03. The signal is "dumped" into the collector load of
Q2. 02 is connected externally at pin 13 and bypassed to ground
at signal frequencies by a capacitor. However, the dc voltage at the
collector of Q2 is dependent on the burst amplitude and therefore

on the input signal strength. As the input signal level falls, more
current is fed into 03 by the ACe loop and the output at pin 6
remains constant while 02 collector voltage increases. At a point
predetermined by 02 collector load (the killer·control setting)
the input Q12 of the color·killer circuit is biased "on", shutting
down the second chroma amplifier stage.
The second chroma stage is similar in configuration to the
first stage. The signal input at pin 7 (which is the output from
pin 6) modulates the current source 08. For a maximum gain
voltage setting on pin 10 the signal current passes through 09 to
the output buffer stage 010. 010 is protected from short circuit
currents by a 11. To reduce the stage gain,current is diverted from
09 by biasing the diode 02 into conduction. 02 can be regarded
as a transistor with 100% dc negative feedback applied between
collector and base. Without the feedback path the gain characteristic of the second stage is that of a differential pair, this S shaped
curve would make tracking of ganged color level and contrast
controls quite difficult. In this limiting form the current through
02 is directly profX)rtional to the voltage difference between the
supply and 02 anode and hence to the control voltage at pin 10.
When the input to the color·killer is biased "on", Q13 is turned

"off" and the voltage at the base of 014 rises abruptly. D2 then
takes all the current from 08 and the output at pin 9 is suppressed.

MC1391P CIRCUIT OPERATION

The MC1391P contains the oscillator, phase detector and predriver sections needed for a television horizontal APe loop.

The oscillator is an RC type with one pin (Pin 7) used to can·
trol the timing. The basic operation can be explained easily. If
it is assumed that Q7 is initially off, then the capacitor connected
from Pin 7 to ground will be charged bV an external resistor (RC)

connected to Pin 6. As soon as the voltage at Pin 7 exceeds the

potential set at the base of as bV resistors RB and R10, Q7 will
turn on and 06 will supply base current to 05 and 010. Transistor
010 will set a new. lower potential at the base of as determined
by RB, R9 and R 1O. Then, transistor Q5 will discharge the
capacitor through R4 until the base bias of Q7 falls below that
of as, at wh ich time Q7 will turn off and the cvcle repeats.
The sawtooth generated at the base of Q4 will appear across
R3 and turn off Q3 whenever it exceeds the bias set on Pin 8.
BV adjusting the potential at Pin B, the duty cycle (MSR) at the

predriver output pin (Pin 1) can be changed to accommodate either

tube or transistor horizontal output stages.
The phase detector is isolated from the remainder of the circuit
by R14 and Z2. The phase detector consists of the comparator
Q15, Q16 and the gated current source Q17. Negative going sVnc
pulses at Pin 3 turn off Q12 and the current division between
Q15 and Q16 will be determined bV the phase relationship of the
sync and the sawtooth waveform at Pin 4, which is derived from
the horizontal flvback pulse. If there is no phase difference be·
tween the sync and sawtooth, equal currents will flow in the
collectors of Q15 and Q16 each for half the sync pulse period.
The current in Q15 is turned around by Q1B so that there is no
net output current at Pin 5 for balanced conditions. When a phase
offset occurs, current will flow either in or out of Pin 5. This
pin is connected via an external low-pass filter to Pin 7, thus
controlling the oscillator.
Shunt regulation for the circuit is obtained with a zero temperature coefficient from the series combination of 01, 02 and Z1.

MC1391P APPLICATIONS INFORMATION

Although it is an integrated circuit, the MC1391P has all the

loop.
The internal temperature compensated voltage regulator allows
a wide supply voltage variation to be tolerated, enabling operation
from nonregulated power supplies. A minimum value for supply
current into Pin 6 to maintain zener regulation is about 18 rnA.
Allowing 2mA for the external dividers

fc = jJp and p = 3.15 x RC Hz/mA
Increasing RC will raise the de loop gain and reduce the static

phase error (S.P.E.) for a given frequency offset. Secondary effects
are to increase the natural resonant frequency of the loop (wn)
and give a wider pull-in range from an out-of-Iock condition. The

loop becomes more underdamped impulse noise can cause shock

also raise the noise bandwidth excessively causing horizontal jitter

the supply voltage ripple is expected to be less than 100 mV (for
a 30 Volt supply) then RA and RS can be combined and CA

The output pulse width can be varied from 6 jJS to 48 jJS by
changing the voltage at Pin 8 (see Figure 5). However, care

MC1398P (continued)

MC1398P CIRCUIT DESCRIPTION
The MC1398P is capable of providing the entire color processing

function between the second detector and the demodulator for
television color receivers.
A band pass filter from the second detector provides a 50 mV
(p-p) signal (for a saturated color bar pattern) at the input to the
first chroma amplifier stage (02. 03. 08. 09'- 8ecause of 02
emitter load resistor the input impedance is determined primarily
by the bias resistor (R3) and is about 2.3 kilohms. Since 02 is the
current source for the differential pair (03 and Ogl. the chroma
information will pass to the load resistor (R7) and then to the
second chroma amplifier (017'- To avoid overload of 017. the
maximum gain to 017 base is only X3 and by varying the bias at
the base of 09 it is possible to reduce the stage gain by 23 d8
without signal distortion; the signal being "dumped" by 09
collector into the supply. Since this automatic chroma control
action will vary the dc bias at 017 base the emitter load of 017 is
the current source 018. maintaining the de operating current. 018

collector is bypassed externally to prevent ae signal attenuation.
During picture scan time, the chroma signal passes through the
output level control amplifier (010.011.015.021). By changing
the bias on 011 and 015 bases the signal can either pass to the
output pin 2 or be "dumped" into the supply through 011· The
use of buffer stages 010 and 021 prevent distortion at low-signal
levels and the control range is better than 70 dB. The signal output
is also buffered by 014 and 020. thus providing a low impedance
drive of up to 2.0 V (p-p) to the demodulator. with an overall
gain between pins 5 and 2 of 40 dB. To enable the chroma signal
output to reach the amplifiers from 017 collector, 012 is held in
conduction by 05 which in the absence of any input on pin 4 is not
conducting.
This high collector voltage also holds 026 in
conduction, clamping the input to the burst channel and preventing
chroma information reaching the oscillator. During picture retrace
time, a positive-going 4.0 J.l.S pulse from the line sweep transformer
will turn 05 "on" and 07 "off". When 05 collector goes low.
012 will become "cut-off" preventing the burst signal at 017
collector from reaching the output pin 2_ At the same time, 026
turns "off" opening the burst channel. The high collector voltage
of 07 turns on 016 and 022. 016 passes the burst signal from
017 collector to the subcarrier regenerator and 022 "fills-in" for
Q12 during the gate period to prevent a dc shift in the pin 2
output voltage.
The gated burst signal is applied to the oscillator through 027
and 028. 029. 050 and 035 together with 027 and 028 form
an injection locked oscillator circuit. At series resonance of the
crystal connected to pin 8 the impedance of pin 8 is very low,
thereby reducing the 3.579545 MHz carrier level at the base of
050. The signal at the base of 029 is not reduced but the output
voltages in R33 and R42 will change. Any signals outside the

response band of the crystal will appear equally at 050 and 029
bases and be suppressed in the output by the differential amplifier
common-mode rejection ratio (about 40 dB),
To maintain
oscillation. a feedback signal with the correct phase is passed by
035 back to the input of Q27. Careful control of the resistor
ratios ensures that 029 and 050 are operated linearly with about
350 mV (p-p) at R33 and R42. due to self oscillation. A burst
signal as low as 2.0 mV (p-p) ~t the chroma input is sufficient to
cause the oscillator to lock to the reference phase and frequency.
As the burst amplitude increases. the level at 029 and 050
collectors changes and this shift is used to provide the automatic
chroma control function. 042 and Q45 form a modified differential
amplifier and with zero offset bias Q45 conducts most of the
current from 043. As an increasing burst level swings Q29 and
050 collectors, the ~urrent from 043 is shunted into 042. At a
point predetermined by the setting of the automatic chroma control
connected to pin 10. the composite lateral PNP of 047 and 046
will be biased into conduction. This amplifier has a gain of unity
and a filter capacitor (connected to 046 base) prevents any
tendency to oscillations. Diode CRg provides thermal compensation to ensure a steady color-killer threshold point. The increasing current through 013 emitter is used to control 09 base,
attenuating the input signal as the burst amplitude increases. The
current from 013 also keeps 019 in saturation. When the input
signal becomes too small for satisfactory COlor rendition, 013
current falls and Q19 comes out of saturation. This means 025
will saturate, clamping 021 base and "killing" the chroma output
stage. R24 in the Schmitt trigger circu it ensures that the colorkiller will have hysteresis to prevent fluttering between "on" and
"off" states.
The oscillator output voltages at R33 and R42 are used to
drive 038 and 039 into limiting so that as the burst amplitude increases the oscillator activity to around 700 mV (p-p), there will
be no change in the oscillator output amplitude at pin 13. 038 and
039 are used as current sources with a 1800 phase difference for
the differential pairs 030 and 031. 034 and 037. A small
capacitor attached externally to Q39 collector adjusts the total
phase difference to 135°. Since the signal appearing in the load
resistor R51 will be the vector sum of 031 and 037 signals,
varying the base bias of O~ and 034 will change the oscillator
output phase over the 135 range. 040 and 041 buffer the
oscillator output providing a low impedance drive at pin 13 for
the demodulator.
To minimize crosstalk between the burst and chroma channels,
separate bias chains are used. Further, the Qscillator bias chain
is zener regulated to prevent phase shifts in the' reference output
with power-supply variations.

CIRCUIT DESCRIPTION
The MC1446L is designed to translate a positive 4.0 mV

6. The current in the second stage of the ampl ifier is set by
the lBO-ohm resistor in the emitter of the current source.
It can be seen that this resistor has one diode drop
(approximately 750 mV) across it. Therefore. an analysis
will show that the voltage drop across the 775-ohm load
resistor in the second stage will be approximately two diodes
when the differential amplifier is balanced. Accounting for
the additional diode voltage drop of the emitter-follower output transistor will set the output dc level at two diodes
above ground or very near the center of MTTL threshold.

signal from a plated wire memory to an MTTL "1" level, or a

negative 4.0 mV to an MTTL "0" level. This sense amplifier also
eliminates the requirement for a bipolar switch in series with the

plated wire because the bit selection is done inside the sense
amplifier.
The circuit operation can be described in sections as follows:

1. All channels have been designed for low input offsets 0.5 V typical.
2. Channel "ORing" is accomplished by using common collector load resistors for four differential amplifier pairs.
3. Channel

7. The strobe circuit works by steering current in the second
stage. When the strobe is low. the entire current of the second stage current source is steered through the 775-ohm
load resistor. This clamps the output to a low state so that
an input signal cannot cause an output. When the strobe is
high. the current is steered through the second stage differential amplifier pair and the output will go to a level
dictated by the presence of an input Signal.

selection is accomplished by current steering

through the four differential pairs. The circuit below the
four differential pairs forms a matrix tree which can be
thought of as a l-by-4 decode matrix. The bottom transistor
is the current source for the first stage of gain.
4. DC translation between the first and second stages of gain
;s done through an emitter-follower stage. two diodes and
another emitter follower for each side of the differential
amplifier. The currents in these translator legs are combined
and run through diodes to the negative supply. These
diodes are used to bias both the first and second gain stages.
This also gives the appropriate gain versus temperature and
dc output level versus temperature characteristics.
5. The top of the second stage amplifier is regulated at a voltage
equal to five diode drops above ground. It can be seen that
if the 700 ohm resistor in the regulator has one diode (or
VBE) across it then the 2.8 k ohm resistor will have four
diode drops across it. This makes a five diode drop voltage
above ground that is fairly independent of the positive supply.

8. The output circuit of the sense amplifier may be thought
of as a push-pull type. The emitter of the push transistor is
brought out to a separate pin from the collector of the
pull transistor. This will facilitate "Wire DRing" the outputs of several sense amplifiers. Several emitter outputs
can be wired together along with only one collector pulldown transistor. The unused collectors of the pulldown
transistor must be grounded. An example of the use of
"Wire DRing" is to have four MC1446 devices wired-OR into
a l6-channel sense amplifier in which a channel may be
selected by selecting channels in parallel at the amplifier
inputs and strobing the proper sense amplifier.

APPLICATIONS INFORMATION
The MC1446 is designed to convert signals as small as positive
or negative 4.0 mV to MTTL logic levels. The output level of the
sense amplifier with no in put signal presen t and with the strobe
high is typically 1.4 volts (typical input threshold of MTTL logicl.
Hence. if the strobe goes high during the absence of an input
signal from the plated-wire memory, the sense amplifier output
will rise to 1.4 volts. This condition could cause false outputs;
therefore careful considerations must be given to strobe timing.
Figure 21 illustrates a typical timing sequence of the MCI446
device as recommended for proper operation.
Figure 22 shows how these sense amplifiers are used in an

N-word-line-by-32-bit basic memory plane organized as 4-N words
of 8 bits each. During a read cycle. the read current is pulsed
through a selected word-line and thus generates o'utputs to all of
the 32-bit positions in the line. The internal one-of-four decoder
selects the desired channeis of the eight sense amplifiers for a
particular system word. When the strobe goes high. the sense
amplifier outputs switch aCCOrding to the data present at the amplifier inputs. The data readout on the other 24-bit lines is not lost
due to the Non-Destructive Read-Out properties of a plated-wire
memory. On the next read cycle the decoder of the sense amplifier
in combination with the selected word-line determines the a-bits
of data to read.

MC1446L (continued)
APPLICATIONS INFORMATION (continued)
FIGURE 21 - TYPICAL TIMING SEQUENCE
Memory organizations that have more than four words per
vvord-line require that the sense amplifier outputs be wire..()Red.

To wire-OR the outputs of several sense amplifiers all of the
emitters of the output-pull up transistors are tied together. Only
one collector of the pulldown transistors is tied to the wire-O Red
emitters of the pullup transistors. The remaining pulldown tran-

sistors must be grounded as noted in Figure 23. Ten or more
sense amplifiers may be wire-ORad together without any reduction
in usable logic levels since only one sense amplifier per bit is on at
any given time. Variations in propagation delay time (tpd), versus
the number of wire-ORed sense ampHfiers and the output capacitance are given in Figure 24.
The fast propagation delay time and low threshold of the
MC1446 make it useful as the sense amplifier for the MCM7001
N-channel MOS memory_ The data output of the MCM7001 is
referenced around +7.5 volts; thus the po"",r supply inputs of the
MC1446. as well as the MECL-Ievel Channel Select and Strobe
inputs, are translated to MTTL and then referenced around this
level, as shown in Figure 25. The minimum 200 fJ,A current from
the memory generates an input of 20 mV which is easily detected
by the MC1446. The MC1446 otuput is a TTL-level signal with a
+7.5 volt reference. This signal can be translated back to MECL
levels with a zener diode as shown.

APPLICATIONS INFORMATION

FIGURE 13 - POWER-5UPPL Y PROTECTION
TO MEET POWER'()FF FAULT CONDITIONS
The Electronic Industries Association (EIA) hes released the
RS232C specification detailing the requirements for the interface
between data processing equipment and data communications
equipment. This standard specifies not only the number and type
of interfece leads, but also the voltage levels to be used. The
MCI488L quad driver and its companion circuit, the MCI489L
quad receiver, provide a complete interfece system between DTL
or TTL logic levels and the RS232C defined levels. The RS232C
requirements as applied to drivers are discussed herein.
The requirad driver voltages are defined as between 5 and 15volts in magnitude and are positive for a logic "0" and nagative for
a logic ",". These voltages are so defined when the drivers are
terminated with a 3000 to 7ooQ-ohm resistor. The MCI488L meets
this voltage requirement by converting a DTLlTTL logiC level into
RS232C levels with one stage of inversion.
The RS232C specification further requires that during transitions, the driver output slew rate must not exceed 30 volts per
microsecond. The inherent slew rate of the MCI488L is much too

FIGURE 12 - SLEW RATE versus CAPACITANCE
FOR ISC = 10 mA
would be excessive. Therefore, if the system is designed to permit

10 00

low impedances to ground at the power-supplies of the drivers, a

diode should be placed in each power-supply lead to prevent overheating in this fault condition.

These two diodes. as shown in

Figure 13, could be used to decouple all the driver packages in a
system. (These same diodes will allow the MCI488L to withstand

00

momentary shorts to the ±25-volt limits specified in the earlier

=3IV'",

Standard RS2328.1 The addition of the diodes also permits the
MC1488L to withstand faults with power-supplies of less than the
9.0 volts stated above.
The maximum short-circuit current allowable under fault conditions is' more than guaranteed by the previously mentioned
10 rnA output current limiting.

fast for this requirement. The current limited output of the device
can be used to control this slew rate by connecting a capacitor to

each driver output. The required capacitor can be easily determined
by using the relationship C = ISC x /l,T/aV from which Figure 12 is
derived. Accordingly, a 330-pF capacitor on each output will
guarantee a worst case slew rate of 30 volts per microsecond.
The interface driver is also required to withstand an accidental
short to any other conductor in an interconnecting cable. The worst

The MC1488L is an extremely versatile line driver with a myriad
of possible applications. Several features of the drivers enhance
this versatility:
1. Output Current Limiting - this enables the circuit designer
to define the output voltage levels independent of power-supplies
and can be accomplished by diode clamping of the output pins.

Figure 14 shows the MC1488L used as a DTL to MOS translator
where the high·level voltage output is clamped one diode above
ground.

The resistor divider shown is used to reduce the output

voltage below the 300 mV above ground MOS input level limit.
2. Power-Supply· Range - as can be seen from the schematic
drawing of the drivers, the positive and negative driving elements
of the device are essentially independent and do not require matching power-supplies. In fact .. the positive supply can vary from a
minimum seven volts (required for driving the negative pulldown
seetio!"!) to the maximum specified 15 volts. The negative supply
can vary from approximately ..:.2.5 volts to the minimum specified

possible Signal on any conductor would be another driver using a

plus or minus 15-volt, 500-mA source. The MCI488L is designed to
indefinitely withstand such a short to all four outputs in a package
as long as the power-supply voltages are greater than 9.0 volts (i.e.,
Vcc;;..9.0 V; Vee.;;;-9.0 V). In some power-supply designs, a loss

-15 volts. The MC1488L will drive the output to within 2 volts of
the positive or negative supplies as long as the current output limits
are not exceeded. The combination of the current-limiting and
supply-voltage features allow a wide combination of possible out-

APPLICATIONS INFORMATION

General Information
The Electronic Industries Association (E IA) hasreleased the AS-232C
specification detailing the requirements for the interface between
data processing equipment and data communications equipment.
This standard specifies not only the number and type of interface
leads, but also the voltage levels to be used_ The MC1488L quad
driver and its companion circuit, the MC1489L quad receiver,

provide a complete interface svstem between DTL or TTL logic
levels and the AS-232C defined levels. The AS-232C requ irements
as applied to receivers are discussed herein.
The required input impedance is defined as between 3000 ohms
and 7000 ohms for input voltages between 3.0 and 25 volts in
magnitude; and any voltage on the receiver input in an open circuit

condition must be less than 2.0 volts in magnitude. The MC1489
circuits meet these requirements with a maximum open circuit voltage of one VBE (Aef. Sect. 2.41.
The receiver shall detect a voltage between -3.0 and -25 volts

as a logic "1" and inputs between +3.0 and +25 volts as a logic "0"
(Ref. Sect. 2.3), On some interchange leads, an open circuit or
power "OFF" condition (300 ohms or more to groundl shall be
decoded as an "OFF" condition or logic "1" (Aef. Sect. 2.51. For
this reason, the input hysteresis thresholds of the MC1489 circuits
are all above ground. Thus an open or grounded input will cause
the same output as a negative or logic ", .. input.

Device Characteristics
The MC 1489 interface receivers have internal feedback from the
second stage to the input stage providing input hysteresis for noise

rejection. The MC1489L input has typical turn-on voltage of 1.25
volts and turn-off of 1.0 volt for a typical hysteresis of 250 mV.
The MC1489AL has typical turn-on of 1.95 volts and turn-off of
0.8 volt for typically 1.15 volts of hysteresis.
Each receiver section has an external response control node in
addition to the input and output pins, thereby allowing the designer to vary the input threshold voltage levels. A resistor can be
connected between this node and an external power-supply. Figures 6, 8 and 9 illustrate the input threshold voltage shift possible
through this technique.
This response node can also be used for the filtering of highfrequency. high-energy noise pulses. Figures 12 and 13 show
typical noise-pulse rejection for external capacitors of various sizes.
These two operations on the response node can be combined
or used individually for many combinations of interfacing applications. The MC1489 circuits are particularly useful for interfacing
between MOS circuits and MDTLlMTTL logic systems. In this
application, the input threshold voltages are adjusted (with the
appropriate supply and resistor values) to fall in the center. of the
MOS voltage logic levels. (See Figure 14)
The response node may also be used as the receiver input as
long as the designer realizes that he may not drive this node with
a low impedance source to a voltage greater than one diode above
ground or less than one diode below ground. This feature is
demonstrated in Figure 15 where two receivers are slaved to the
same line that must still meet the RS-232C impedance requirement.

The MC1506L consists of a reference current amplifier,
and R-2R ladder, and six high-speed current switches_ For
many applications, only a reference resistor and a reference
supply voltage need be added.
The switches are inverting in operation, therefore a low
state at the input turns on the specified output current
component. The switches use a current steering technique
for high speed and a termination amplifier that consists of
an active load gain stage with unity gain feedback. The
termination amplifier holds the parasitic capacitance of the
ladder at a constant voltage during switching and provides
a low impedance termination of equal voltage for all legs
of the ladder.
The R-2R ladder divides the reference amplifier current
into binarily-related components which are fed to the
switches. Note that there is always a remainder current
that is equal to the least significant bit. This current is
shunted to ground, and the maximum current is 63/64 of
the reference amplifier current, or 1.969 mA for a 2.0 mA
reference current if the NPN current source pair is
perfectly matched.

The MC1506L current switches have been designed for
high-speed operation and as a result have a restricted out·
put voltage range, as shown in Figures 4 and 5. When a
current switch is turned "off", the follower emitter is
near ground and a positive voltage on the output terminal
can turn "on" the output diode and increase the output
current level. When a current switch is turned "on", the
negative output voltage range is restricted. The base of
the termination circuit Darlington amplifier is one diode
voltage below ground; thus a negative voltage below the
specified safe level will drive the low current device of the
Darlington into saturation, decreasing the output current
level.
For example, at +250 C the allowable voltage compliance
on pin 4 to maintain six-bit accuracy is ±O.4 volt. With a
full scale output current of 2.0 mA, the maximum resistor
value that can be connected from pin 4 to ground is
200 ohms.

Accuracy
Absolute accuracy is the measure of each output current
level with respect to its intended value, and is dependent
upon relative accuracy and full scale current drift. Relative
accuracy is the measure of each output current level as a
fraction of the full scale current. The relative accuracy of
the MC1506L is essentially constant with temperature due
to the excellent temperature tracking of the monolithic
resistor ladder. The reference current may drift with
temperature, causing a change in the absolute accuracy
of output current.

The best temperature performance is achieved with a

the pair.

some mismatch in the NPN current source pair. The
accuracy test circuit is shown in Figure 10. The 12·bit
converter is calibrated for a full scale output current of
1.969 mAo This is an optional step since the MC1506L
accuracy is essentially the same between 1.5 to 2.5 mAo
Then the MC1506L full scale current is trimmed to the
same value with R 12 so that a zero value appears at the
error amplifier output. The counter is activated and the
error band may be displayed on an oscilloscope, detected
by comparators, or stored in a peak detector.
Two 6·bit D·to·A converters may not be used to construct a 12-bit accurate D-to·A converter. 12·bit accuracy
implies a total error of ±1/2 of one part in 4096, or
±O.012%, which is more accurate than the ±O. 78% specifi·
cation provided by the MC1506L.
MUltiplying Accuracy
The MC1506L may be used in the mUltiplying mode
with six·bit accuracy when the reference current is varied
over a range of 64: 1. The major source of error is the
bias current "Of the termination amplifier. Under "worst
case" conditions these six amplifiers can contribute a total
of 6.0 IlA extra current at the output termi nal. If the
reference current in the mUltiplying mode ranges from
60 IlA to 4.0 mA, the 6.0 IlA contributes an error of
0.1 LSB. This is well within six· bit accuracy.
A monotonic converter is one which supplies an increase
in current for each increment in the binary word. Typically, the MC1506L is monotonic for all values of reference
current above 0.5 mA. The recommended range for
operation with a dc reference current is 0.5 to 4.0 mA.
Settling Time
The "worst case" switching condition occurs when all
bits are switched "on", which corresponds to a high·to-Iow
transition for all bits. This time is typically 150 ns to
within ±.1/2 LSB, while the turn "off" is typically under
50 ns.
The slowest single switch is the least significant bit,
which turns "on" and settles in 50 ns and turns "off" in
30 ns. In applications where the D·to-A converter func·
tions in a positive·going ramp mode, the "worst case"
switching condition does not occur, and a settling time
of less than 150 ns may be realized.
Reference Amplifier Drive and Compensation
The reference amplifier provides a voltage at pin 12 for
converting the reference voltage to a current, and a turn·

around circuit or current mirror for feeding the ladder.
The reference amplifier input current, 112, must always
flow into pin 12 regardless of the setup method or reference
voltage polarity.
Connections for a positive reference voltage are shown
in Figure 6. The reference voltage source supplies the full
current 112. Compensation is accomplished by Miller feed·
back from pin 14 to pin 13. This compensation method
yields the best slew rate, typically better than 2.0 mAIlls,
and is independent of the value of R 12. R 13 must be used
to establish the proper impedance for compensation at
pin 13. For bipolar reference signals, as in the mUltiplying
mode, R 13 can be tied to a negative voltage corresponding
to the minimum input level. Another method is shown
in Figure 22.
It is possible to eliminate R13 with only a small sacri·
fice in accuracy and temperature drift. For instance when
high·speed operation is not needed, a capacitor is connected
from pin 14 to VEE. The capacitor value must be increased
when R 12 is made larger to maintain a proper phase
margin. For R 12 values of 1.0, 2.5, and 5.0 kilohms,
minimum capacitor values are 50, 125, and 250 pF.
Connections for a negative reference voltage are shown
in Figure 7. A high input impedance is the advantage of
this method, but Miller feedback cannot be used because
it feeds the input signal around the PNP directly into the
high impedance node, causing slewing problems and high
frequency peaking. Compensation involves a capacitor
to VEE on pin 14, using the values of the previous para·
graph. The negative reference voltage must be at least
3.0 V above VEE. Bipolar input signals may be handled
by connecting R12 to a positive reference voltage equal to
the peak positive input level at pin 13.
When a dc reference voltage is used, capacitive bypass
to ground is recommended. The 5.0 V logic supply is not
recommended as a reference voltage. If a well regulated
5.0 V supply which drives logic is to be used as the refer·
ence, R 12 should be decoupled by connecting it to +5.0 V
through another resistor and bypassing the junction of
the two resistors with 0.1 IlF to ground. F or reference
voltages greater than 5.0 V, a clamp diode is recommended
between pin 12 and ground.
If pin 12 is driven by a high impedance such as a
transistor current source, none of the above compensation
methods apply and the amplifier must be heavily compen·
sated, thus decreasing the overall bandwidth.

Voltage outputs of a larger magnitude are obtainable
with this circuit which uses an external operational amplifier as a current to voltage converter. This configuration
automatically keeps the output of the MC1506L at ground
potential and the operational amplifier can generate a
positive voltage limited only by its positive su pply voltage.
Frequency response and settling time are primarily determined by the characteristics of the operational amplifier_
In addition, the operational amplifier must be compensated
for unity gain, and in some cases overcompensation may
be desirable.
Note that this configuration results in a positive output

the digital input_

Vref
Since ±15 V and +5.0 V are normally available in a
combination digital-to-analog system, only the -5.0 V
need be developed. A resistor divider is sufficiently accurate since the allowable range on pin 5 is from -2.0 to
Va
-S.O volts. The 5.0 kilohm pulldown resistor on the amplifier output is necessary for fast negative transitions.
Full scale output may be increased to as much as 32 volts
by increasing RO and raising the +15 V supply voltage to
35 V maximum. The resistor divider should be altered to
comply with the maximum limit of 40 volts across the
MCl723G. Co may be decreased to maintain the same
ROCO product if maximum speed is desired.
Programmable Power Supply
The circuit of Figure 19 can be used as a digitally
programmed power supply by the addition of thumbwheel
switches and a BCD·to-binary converter. The output voltage can be scaled in several ways, including 0 to +6.3 volts
in O.l-volt increments, ±O.05 volt; or 0 to 31.5 volts in
O.5-volt increments, ±O.25 volt.

Bipolar outputs may also be obtained by using a polarity
switching circuit. The circuit of Figure 21, gives 6-bits
magnitude plus a sign bit. In this configuration the operational amplifier is switched between a gain of + 1.0 and
-1.0. Although another operational amplifier is required,
no more space is taken when a dual operational ampl ifier
such as the MC155SG is used. The transistor should be
selected for a very low saturation voltage and resistance.

Bipolar inputs can be accepted by using any of the
previously described methods, or applied differentially to
R121 and R122 or R131 and R132. Vo will be a bipolar
signal defined by the above equation. Note that the circuit
shown accepts bipolar differential signals but does not have
a negative common-mode range. A vj!,ry useful method is
to connect R 121 and R 122 to a positive reference higher
than the most positive input, and drive R131 and R132.
This yields high input impedance, bipolar differential and
common-mode range. The compensation depends on the

Compensation is necessary for loop stability and depends on
the type of operational amplifier used. If a standard 1.0 MHz
operational amplifier is employed. it should be overcompensated
when possible. If this cannot be done, the reference amplifier
can furnish the dominant pole with extra Miller feedback from
pin 14 to 13. If the MC1723 or another wideband amplifier is
used, the reference amplifier should always be overcompensated.

THREE-QUADRANT OPERATIONAL AMPLIFIER

active filter applications, the amplifier is especially useful since it offers four-quadrant operation with very
wide bandwidth.

The amplifier is a single-gain stage especially designed for
high gain and fast response. Very high impedance current
sources provide a typical resistance of 20 megohms at
pin 13, which is ,the gain node of the circuit and its
major RC pole. The input of the amplifier is protected
against breakdown of the NPN differential pair, and the
output is short-circuit protected. Since the amplifier is a
single-gain stage with all NPN transistors in the signal
path, it has one limitation when compared with standard
operational amplifiers. The amplifier transfer characteristic, Figure 4, shows that the output can swing no more
negative than -2.0 volts with respect to the inputs.
Hence, the circuit is called a three-quadrant operation'al
amplifier. The amplifier may be used as a standard operational amplifier in the noninverting unity gain mode
with an output swing of ±11 V minimum, and as an inverting amplifier to convert negative voltages to positive
voltages. For output swings under 4.0 volts (p-p). as in

FIGURE 18 - COMPARATOR EQUIVALENT CIRCUIT

The comparator equivalent circuit is shown in Figure 18.
It may be envisioned as two comparators with common
inputs and a reference voltage source which sets equal
and opposite thresholds. A positive reference voltage on
pin 11 sets the thresholds as in the transfer characteristic
of Figure 19. If, for example, pin 6 is grounded, when the
input signal on pin 5 exceeds Vth (+), the UP output
goes high. When the inputon pin 5 exceeds Vth (-) in the
negative direction, the DOWN output goes high.

V ll1

6

VIO= V5 - V6

In applications where a single output is desired, as in a
window comparator, the outputs may be connected in
"wired OR" ·if the reference voltage polarity is reversed.
This inverts the output polarity so that when the input is
between thresholds the outputs are in a normal high
state. It also interchanges the outputs so that pin 7 reo
sponds to an input of Vth (+), and pin 9 to an input of
Vth (-). See Figure 20, which is the transfer characteristic
curve. When the outputs are connected together, a low
output state results for an input outside the threshold
window.

TRACKING A-TO-D CONVERTERS

step of 16 J.1A instead of a J.1A, and the summing node
would pull back to -40 mV instead of zero. If the com·
parator thresholds were closer to ground than ±40 mV,
this transition would cause the DOWN comparator to
fire and the D·to-A current would decrease. Thus the
system would oscillate between two output values for
this particular transition. This mayor may not be undesirable, depending on system requirements. Both outputs would be within ±1 LSB of the correct value,
which is a standard A·to·D converter accuracy specification. However, the end of conversion feature described
in a later section cannot be used unless the system settles
to a stable value.
With thresholds of ± 1 LSB, the system has a typical
hysteresis of ± 1 LSB, as shown on the transfer
characteristic of Figure 35. If the input voltage is ramping
up and has just fired the UP comparator, the summing
node pulls back to a typical value of zero. With a change
in ramp direction, the input must decrease by 1 LSB to
fire the DOWN comparator. This hysteresis allows for
D-to-A converter error and also lends noise immunity to
the system.
An A-to·D converter using a O-to-A converter in its
feedback loop cannot be any more accurate than the ac·
uracy of the D-to·A converter plus 1/2 LSB quantization
error. In the case of the MC150BL-8, MC1408L·B,
MC1506, and MC1406, this D-to·A accuracy is specified
as ± 1/2 LSB. In a tracking converter with the comparator thresholds set to zero, the A·to-D converter output
toggles between two values, each value within ±1 LSB of
the correct value. The ± 1/2 LSB error of the D·to-A
converter is added to the ± 1 LSB error of the converter,
resulting in a system error of ±1 1/2 LSB. The comparator offset or mismatch error (±E) can be trimmed out
and eliminated as a source of additional error.
If the MC1507 comparator thresholds are set to ±1
LSB, the ±1/2 LSB of the D-to-A converter must also
be added, again, giving a system error of ± 1 1/2 LSB.
In addition, the comparator mismatch error, (+E). must
be added to both the UP threshold and the DOWN threshold.
In order to insure thresholds of at least ±40 mV,
Vref for the comparator should be no lower than ±44
mV for the MC1507L and ±50 mV for the MC1407L.
This results in an additional ±0.2 LSB error in the
MC1507L and an additional ±0.5 LSB error in the
MC 1407 L. Total system error for an 8-bit converter, with
±1 LSB threshold to eliminate toggling and to improve
noise 'immunity, is therefore ± 1.7 LSB for a system with
the MC1507 L, ±2.0 LSB for a system with the MC1407 L.

A tracking A-to-D converter is a system with a digital
output which continuously follows the analog input. It
can be thought of as an "analog-to-digital operational
ampl ifier" since as a system it has many sim ilar specifications: slew rate, propagation delay, settling time, and
adjustable scale factor. The tracking converter is normally
used in high-speed applications which require conversion
times on the order of l-to·l 00 J.1s.
Successive approximation conversion is the other
major method used for A-to-D conversion in this speed
category. The advantages of the tracking system over
successive approximation system include: 1) the elimination of the sample and hold function at the input,
2) a digital output which is continuously present and can
be used in asynchronously sampled systems, and 3) a
conversion or update period equal to slightly more than
one D·to-A converter settling time. The major disadvantage of the method is that if the system slew rate
is exceeded, the conversion time increases. A full scale
input step function requires a conversion time of 2 n
times the tracking update rate, where n is the number of
bits. The full-scale conversion time can be shortened,
however, using methods which will be described later,
and shown in Figure 36.
Another advantage of the track ing system is that,
unlike the successive approximation approach, the output
always indicates a value equal to the present or very
recent input level. Therefore, in many instances latches
or special timing are unnecessary for data readout.

BASIC 8-BIT SYSTEM
An easily constructed tracking A-to-D converter using
the MC1407L, two up/down counters, a quad NAND
gate, and a monolithic D-to-A converter such as the
MC1406 or MC140BL-B is shown in Figure 34. Assuming
a full scale input range of 10 volts, the reference voltage
is chosen so that the UP and DOWN thresholds are at
least ±1 LSB from ground. For an a·bit converter, this
would be 10 V /256 or ±40 mV. The converter operation
is described by assuming that Vin = 0 and the counter
output is 00000000. The D-to-A converter is pulling no
current so the drop across R in is essentially zero. Now
assume Vin rises until it reaches 40 mV, which is the UP
comparator threshold. The UP comparator fires and on
the next positive edge of the clock, a pu Ise is fed to the
UP input of the counter. As shown in the converter
transfer characteristic, the counter output increases to
00000001. The D-to·A converter now pulls B J.1A, so the
summing node voltage drops down to zero. In a similar'
manner the system could count up to any value up to
the full scale 11111111 count.
Since the O-to-A converter output current levels are
rated to be accurate to within ±1/2 LSB, the comparator
thresholds must be set to allow for this error. If, for
instance, all the D-to-A converter error occurred at one
transition, one output could be 1/2 LSB or 4J.1A low and
the next would be 4 J.1A high. This wou Id be a current

High-speed operation is possible with this converter
due to the use of current summing. No operational
amplifier is used in the feedback loop, so the principal
delays involved are the D-to-A converter settling time and
the comparator delay time. The loop delay in Figure 34
is approximately 500 ns, allowing 150 ns for the
MC1507L comparator with a small overdrive. The maximum clock frequency is determined by the loop delay.

APPLICATIONS INFORMATION (continued)

multivibrator quadruples its clock rate, and the system
switches to the "Panic Mode". When the summing node
comes back within 130 mV of ground, the system
resumes its normal clock rate and cleanly settles into
the tracking mode.
The Panic Mode system is well suited to multiplexed
data acquisition systems where the voltage presented to
the input may step quickly between various levels. Also,
the power bandwidth has quadrupled and the system will
follow 25 kHz full scale sine waves with slightly more
distortion than when in the normal tracking mode_

HIGH-SPEED SYSTEM

When the input voltage to the tracking A-to-O converter varies more rapidly than the system slew rate, the
output will be unable to follow the input and thus there
is no need for the O-to-A converter to settle between
each clock pulse. A second MC1507L may be employed
as a window detector to indicate when the converter
summ ing node is more than a given voltage from the
comparator deadband, as shown in Figure 36. When the
window detector fires, the MC4024 voltage controlled

TYPICAL PERFORMANCE DATA
FOR 6-BIT SYSTEM

G·BIT TRACKING A·TO·D CONVERTER

A G-bit tracking A-to·D converter may be constructed
with the MC 1506_ The circuit differs in one respect from
the 8-bit system since the MC1506 has inverting logic
inputs. In order to preserve negative feedback in the
loop, a hex inverter may be used ahead of the D-to·A
converter_ However, if inverted logic outputs can be
tolerated, the hex inverter is not necessary. By merely
interchanging the UP and DOWN comparator outputs
the counting direction is inverted, compensating for the
inversion in the D-to·A converter.
The MC1506 has a faster settling time and one·fourth
the number of output states, so the advantage of this
system is higher speed.

END OF CONVERSION

A useful feature of the dual threshold tracking A·to·D
converter is a simple method of sensing end of con·
version. When the system has reached equilibrium the
summing·node voltage is in the comparator deadband
and both UP and DOWN outputs are low. These outputs
can be fed to an OR gate to provide an EOC indication,
or to three NAND gates as shown in Figure 46. This is a
feature which is not available with a single threshold
system, since its comparator is continually changing state.
If the A·to·D converter data is stored in latches, the
EOC output can be fed to a NAND gate with the latch
strobe command to insure accurate data transfer. If the
strobe command occurswhile the system is searching, the
output from the previous conversion will be retained.
However, an advantage of the track ing system is that,
unlike successive approximation, its output always reo
flects a value equal to the present or very recent input
level.

APPLICATIONS INFORMATION (continued)
PEAK DETECTING TRACK AND HOLD CIRCUIT
WITH DIGITAL OUTPUT AND INFINITE HOLD TIME
The basic tracking A-to-D converter may be used as a
positive peak detecting track and hold system by disabling the DOWN counting function. This may be performed by gating or by eliminating the DOWN connections. The system may be reset to zero by the counter
reset or by re-enabling the DOWN function, shorting the
converter input to ground, and allowing the output to
track to zero. If the DOWN gate is disconnected from the
MC74193 counter, this counter input must be connected
high to allow proper functionin~ of the UP counter.
A negative peak detecting track and hold system is
implemented by modifying the input of the above circuit
to accept negative input signals, as shown in Figure 47.

FIGURE 55 - TRANSFER CHARACTERISTIC OF
SET·POINT CONTROL

Variable Deadband Set·'Point Controls are used in
control systems to compensate for large time constants
in the controlled systems. The dual output control shown
in Figure 54 controls two variables, such as heating and
cooling, that keep a controlled variable, such as temper·
ature, centered on the set point or operating point.
The set point voltage need not be produced by the
potentiometer but can be a reference voltage supplied by
the controlled system. As the set point moves linearly
this voltage could come from an MC1508L·8 D·to·A
converter which would provide digital control of the set
point. Deadband could be controlled by the system
in a similar manner.

CIRCUIT DESCRIPTION
The MC1508L-8 consists of a reference current amplifier, an

a low impedance termination of equal voltage for all legs of
the ladder.
The R·2R ladder divides the reference ampl ifier current into
binarily·related components, which are fed to the switches. Note
that there is always a remainder current which is equal to the
least significant bit. This current is, shunted to ground, and the
maximum output current is 255/256 of the reference amplifier
current, or 1.992 mA for a 2.0 mA reference amplifier current
if the NPN current source pair is perfectly matched.

R~2R

ladder, and eight high-speed current switches. For many
applications, only a reference resistor and reference voltage need
be added.
The switches are noninverting in operation, therefore a high

state on the input turns on the specified output current component.
The switch uses current steering for high speed, and a termination

value of this voltage will be the maximum allowable negative out·
put swing.

Connections for a positive reference voltage are shown in Figure
7. The reference voltage source supplies the full current 114. For
bipolar reference signals, as in the multiplying mode, R15 can be
tied to a negative voltage corresponding to the minimum input
level. It is possible to el iminate R 15 with only a small sacrifice
in accuracy and temperature drift. Another method for bipolar
inputs is shown in Figure 25.
The compensation capacitor value must be increased with increases in R14 to maintain proper phase margin; for R14 values
of 1.0, 2.5 and 5.0 kilohms, minimum capacitor values are 15,

37, and 75 pF.

Output Current Range
The output current maximum rating of 4.2 mA may be used
only for negative supply voltages more negative than -6.0 volts,
due to the increased voltage drop across the 350-0hm resistors in
the reference current amp I ifier.
Accuracy

The capacitor may be tied to either VEE or

Absolute accuracy is the measure of each output current level
with respect to its intended value, and is dependent upon relative
accuracy and full scale current drift. Relative accuracy is the
measure of each output current level as a fraction of the full.scale
current. The relative accuracy of the MC1508L·8 is essent~lIy
constant with temperature due to the excellent temperature tracking of the monolithic resistor ladder. The reference current may
drift with temperature, causing a change in the absolute accuracy

ground. but using VEE increases negative supply rejection.
A negative reference voltage may be used if R14 is grounded
and the reference voltage is applied to R15 as shown in Figure S.
A high input impedance is the main advantage of this method.
Compensation involves a capacitor to VEE on pin 16, using the
values of the previous paragraph. The negative reference voltage

must be at least 3.0,volts above the VEE supply. Bipolar input
signals may be handled by connecting R14 to a positive reference
voltage equal to the peak positive input level at pin 15.
When a dc reference volt~ge is used. capacitive bypass to ground
is recommended. The 5.0-V logic supply is not recommended as
a reference voltage. If a well regulated 5.Q..V supply which drives
logic is to be used as the reference, R 14 should be decoupled by
connecting it to +5.0 V through another resistor and bypassing
the junction of the two resistors with 0.1 p.F to ground. For
reference voltages greater than 5.0 V, a clamp diode is recommended between pin 14 and ground.
If pin 14 is driven by a high impedance such as a transistor
current source, none of the above compensation methods apply
and the amplifier must m; heavily compensated, decreasing the

01 output current. However, the MC1508L-B has a very low lull

a!lowing some mismatch in the NPN current source pair. The
accuracy test circuit is shown in Figure 4. The 12-bit converter
is calibrated for a full scale output current of 1.992 rnA. This is
an optional step since the MC150SL·8 accuracy is essentially the
same between 1.5 and 2.5 rnA. Then the MC1508L·8 circuits' full
scale current is trimmed to the same value with R 14 so that a zero
value appears at the error amplifier: output. The counter is activated
and the error band may be displayed on an oscilloscope, detected
by comparators, or stored in a peak detector.
Two S·bit D·to-A converters may not be used to construct a
16-bit accurate D-to-A converter. 16-bit accuracy implies a total

overall bandwidth.
Output Voltage Range
The voltage on pin 4 is restricted to a range of -0.6 to +0.5
volts at +25 0 C, due to the current switching methods employed

in the MC150SL·S. When a current switch is turned "011", the posi·

A monotonic converter is one which supplies an increase in
current for each increment in the binary word. Typically, the
MC1508L-B is monotonic for all values of reference current above

in beta must be considered for wide temperature range applications. An inverted output waveform may be obtained by using a

load resistor from a positive reference voltage to the collector of

output voltage swing, because pin 4 is held at a constant voltage.
The resistor (RI to VEE maintains the transistor emitter voltage

FIGURE 34 - ANALOG QUOTIENT OF TWO DIGITAL WORDS

FIGURE 33 - ANALOG DIVISION BY DIGITAL WORD

This circuit yields the inverse of a digital word scaled by a
constant. For minimum error over the range of operation. 10 can
be set at 16 IJ.A so that 114Will have a maximum value of 3.984
mA for a digital bit input configuration of 00000001.
Compensation is necessary for loop stabil ity and depends on
the type of operational amplifier used. If a standard 1.0 MHz
operational amplifier is employed, it should be overcompensated
when possible. If the MC1723 or another wideband amplifier is
used, the reference amplifier should always be overcompensated.

Two a-bit, D-to-A converters can be used to build a two digit
BCD D-to-A or A-to-D converter. If both outputs feed the virtual
ground of an operational amplifier, 10:1 current scaling can be
achieved with a resistive current d.ivider. If current output is desired, the units may be operated at full scale current levels of

4.0 rnA and 0.4 rnA with the outputs connected to sum the currents.
The error of the D-to-A converter handl ing the least significant
bits will be scaled down by a factor of ten and thus an MC1408L-6
may be used for the least significant word.

MONOLITHIC POWER BOOSTER
The MC153B/MC1438 is designed as a high current gain amplifier
(70 dB), with unity voltage gain that can deliver load currents up to
±300 mAdc. This device is ideally suited to follow an operational
amplifier (such as MC1556/MC14561 for driving low impedance loads
and improving the overall circuit performance.
• High Input Impedance - 0.4 Meg·Ohm typ - when driving the
MC153B/MC1438, the gain of an operational amplifier will
approach the unloaded open·loop gain. Internal power dissipa·
tion of the operational amplifier will be independent of output
voltage and therefore thermal drift will be reduced.

INTEGRATED CIRCUIT FOR
OPERATIONAL AMPLIFIERS
EPITAXIAL PASSIVATED

CASE 614

• Large Power Bandwidth - 1.5 MHz typ - considerably better than
present operational amplifiers. Bandwidth and slew rate will be
limited by the operational amplifier, not the MC1538/MC143B.
• Low Output Impedance - 10 Ohms typ - allows the MC1538/
MC1438 to drive a capacitive load with greatly reduced phase
shift compared with an operational amplifier. Output voltage
swing capability is much increased when driving small load im·
pedances.
• Adjustable Current Limit - ±5.0 mAdc to ±3oo mAdc
• Excellent Power·Supply Rejection - 1.0 mVIV typ
• Current Gain - 3000 typ

time, the minimum time by which the strobe input may
follow the high level differential input signal without causing
a signal to appear at the amplifier output.

The MC1550 is built with monolithic fabrication techniques
utilizing diffused reSistors and small-geometry transistors.
Excellent AGe performance is obtained by shunting the signal
through the AGe transistor QJ maintaining the operating point
of the input transistor Q •. This keeps the input impedance
constant over the entire AGe range.
The amplifier is intended to be used in a common-emitter,
common-base configuration (Q. and Q2) with QJ acting as ~n
AGe transistor. The input signal is applied between pins 1 and
4, where pin 4 is ac-coupled to ground. DC source resistance
between pins 1 and 4 should be small (less than 100 ohms).
Pins 2 and 3 should be connected together and grounded. Pins
8 and 10 should be bypassed to ground. The positive supply
voltage is applied at pin 9 and at higher frequencies, pin 9
should also be bypassed to ground. The output is taken between pins 6 and 9. The substrate is connected to pin 7 and
should be grounded. AGC voltage is applied to pin 5.

FIGURE 19 - s11 AND s22, INPUT AND OUTPUT
REFLECTION COEFFICIENT

The Y12 shown in Figure 16 illustrates the extremely low feedback of the MC1550
with no contribution from the external mounting circuitry. However, in many
cases the external circuitry may contribute as much or more to the total feedback
than does the MC1550.
To perform more accurate design calculations of gain, stability, and input - output
impedances it is recommended that the designer first determine the total feed·
back of device plus circuitry.
This can be done in one of two ways:
(1) Measure the total Y12 or 512 of the MC1550 installed in its mounting
circuitry, or
(2) Measure the Y12 of the circuitry alone (without the MC1550 installed) and
add the circuit Y12 to the Y12 for the MC1550 given in Figure 16.

RECOMMENDED OPERATING CONDITIONS
In order to avoid local VHF instability. the following set of rules must be
adhered to:
1. An R·C stabilizing network (0.1 /LF in series with 10 ohms) should be
placed directly from pin 9 to ground, as shown in Figures 6 and 7, using
short leads, to eliminate local VHF instabitity caused by lead inductance

to the load.
2. Excessive lead inductance from the V + supply to pin 10 can cause high
frequency instability. To prevent this, the V + by-pass capacitor should
be connected with short leads from the V + pin to ground_ If this capacitor is remotely located a series R·C network (0.1 p.J and 10 ohms) should
be used directly from pin 10 to ground as shown in Figures 6 and 7_

3. Lead lengths from the external components to pins 7, 9, and 10 of the
package should be as short as possible to insure good VHF grounding
for these points.
Due to the large bandwidth of the amplifier, coupling must be avoided be·
tween the output and input leads. This can be assured by either (a) use of
short leads which are well isolated, (b) narrow-banding the overall amplifier
by placing a capacitor from pin 1 to ground to form a low-pass filter in combination with the source impedance, or (c) use of a shielded input cable. In
applications which require upper band· edge control the input low-pass filter
is recommended.

GENERAL OPERATION

The MC1555 is a monolithic timing circuit

~hich

A reset pin is provided to discharge the capacitor thus interrupting the timing cycle. As long as the reset pin is low, the capacitor discharge transistor is turned "on" and prevents the capacitor
from charging. While the reset voltage is applied the digital output
will remain the same. The reset pin should be tied to the supply
voltage when not in use.

uses as its

timing elements an external resistor - capacitor network. It can
be used in both the monostable (one-shot) and astable modes
with frequency and duty cycle controlled by the capacitor and
resistor values. While the timing is dependent upon the external
passive components, the monolithic circuit provides the starting
circuit, voltage comparison and other functions needed for a complete timing circuit. I nternal to the integrated circuit are two
comparators, one for the input signal and the other for capacitor
voltage; also a flip-flop and digital output are included. The com-

parator reference voltages are always a fixed ratio of the supply
voltage thus providing output timing independent of supply voltage.

FIGURE 14 - MONOSTABLE CIRCUIT

+Vcc 15 to 15 V)

Monostable Mode

>
tL

In the monostable mode, a capacitor and a single resistor are
used for the timing network. Both the threshold terminal and the
discharge transistor terminal are connected together in this mode,
refer to circuit Figure 14. When the input voltage to the trigger
comparator falls below 1/3 Vee the comparator output triggers
the flip-flop so that it's output sets low. This turns the capacitor
discharge transistor "off" and drives the digital output to the high
state. This condition allows the capacitor to charge at an exponential rate which is set by the RC time constant. When the
capacitor voltage reaches 2/3 Vee the threshold comparator resets
the flip-flop. This action discharges the timing capacitor and returns the digital output to the low state. Once the flip-flop has
been triggered by an input signal, it cannot be retriggered until
the present timing period has been completed. The time that the
output is high is given by the equation t = 1.1 RA C. Various
combinations of Rand C and their associated times are shown in
Figure 16. The trigger pulse width must be less than the timing
period.

In the astable mode the timer is connected so that it will
retrigger itself and cause the capacitor voltage to oscillate between
1/3 Vce and 2/3 Vee. See Figure 17.
The external capacitor charges to 2/3 Vee through RA and RB
and discharges to 1/3 Vce through RB. By varying the ratio of
these resistors the duty cycle can be varied. The charge and
discharge times are independent of the supply voltage.
The charge time (output highl is given by: tl = 0.695 (RA +RB) C

Note 4.

The input signal can be introduced by use of a transformer
which will allow the output of an audio oscillator to be
coupled in series with the dc input to the regulator. (The
large ac input impedance of the regulator will not load
the oscillator.) A 24 V, 1.0 ampere filament transformer
with the audio oscillator connected to the 110 V primary
winding is satisfactory for this test. vin ~ 1.0 V (rms).

Note 5.

Load regulation is specified for small (S +170 C) changes
in junction temperature. Temperature drift effect must
be taken into account separately for conditions of high
junction temperature changes due to the thermal feedback
that exists on the monolithic chip.

taneous input voltage" required to properly bias the
internal zener reference diode. For output voltages greater

than approximately 5.5 Vdc the minimum "total

instan~

taneous input voltage" must increase to the extent that it
will always exceed the output voltage by at least the
"input output voltage differential".

This parameter states thatthe MC1560/1561 and MC14601
1461 will regulate properly with the input-output voltage
differential (Vin - Vol as low as 2.7 Vdc and 3.0 Vdc re·

Note 6.

The output-voltage adjusting resistors (R 1 and R2) must
have matched temperature characteristics in order to maintain a constant ratio independent of temperature.

The resulting low level output signal (va) will require the
use of a tuned voltmeter to obtain a reading. Special care
should be used to insure that the measurement technique
does not include connection resistance, wire resistance,
and wire lead inductance (i.e., measure close to the case).
Note that No. 22 AWG hook-up wire has approximately
4.0 milliohms/in. dc resistance and an inductive reactance
of approximately 10 milliohms/in. at 100 kHz. Avoid use
of alligator clips or banana plug-jack combination.

GENERAL OPERATING INFORMATION
There is a general tendency to consider a voltage regulator as
simply a dc circuit and to prepare breadboard construction accordingly. The excellent high-frequency performance and fast response
capability of this integrated-circuit regulator, however, makes extra
breadboarding care worthwhile when compared with the limited
performance achieved in other regulators when low~frequency transistors are used in the feedback amplifier. Due to the use of VHF
transistors in the integrated circuit. some VHF care (short, welldressed leads) must be exercised in the construction and wiring of
circuits ("printed-circuit" boards provide an excellent component
interconnection technique).

The circuit must be grounded by a low-inductance connection to
the case of the "R" package, or to pin 100f the "G" package.
A series 4. 7-kn resistor at Pin 5 (Figure 1) will eliminate any VHF
instability problems which may result from lead lengths longer than
a few inches at the regulator output. The resistor body should be as
close to Pin 5 as phYSically possible 1< 112 inch) although the length
of the lead to the load is not critical. If temperature stability is of
major concern, a 4.7-kO resistor should also be placed in series with
Pin 6 in order to cancel any drift due to bias current changes.

If long input leads are used, it may be necessary to bypass Pin 3
with a O.I·"F capacitor (to ground).
The "Shut·Down Control", Pin 2, can be actuated for all possible
output voltages and any values of Co and Cn with no damage to the
circuit. The standard logic levels of RTL. DTL. or TTL can be used
(see Figure 20~. This control can be used to eliminate power con-

The connection to Pin 5 can be made by ~ separate lead directly
to the load. Thus "remote sensing" can be achieved and undesired
impedances (including that of a milliammeter used to measure ILl
can be greatlv reduced in their effect on ZoiJt. A to-ohm resistor
placed from pin t to pin 5 (close to the IC) will eliminate undesirable
lead-inductance effects.
Short-circuit current-limiting is achieved by selecting a value for
RSC which will threshold the internal diode string when the desired
maximum load current flows (see Figure 5). If the device dissipation
and dc safe area limits (Figure 15) are not exceeded. it can be con. tinuously short-circuited at the output without damage.

an ae and de "squelch" control for communications circuits. and as

a dissipation control to protect the regulator under sustained output
short-circuiting (see Figures 21 and 25). As the magnitude of the
input-threshold voltage at Pin 2 depends directly upon the junction

temperature of the IC chip. a fixed de voltage at Pin 2 will cause
automatic shut-down for high junction temperatures (see Figure 23.
a and b). This will protect the chip, independent of the heat sinking
used, the ambient temperature, or the input or output voltage levels.
Due to the small value of input current at Pin 8, the external
resistors, R1 and R2, can be selected with little regard to their par-

GENERAL INFORMATION
Latch·up of these and other regulators can occur if:

1. There are plus and minus voltages available
2. A load exists between Va + and Vo- (This "common load" may be something
inconspicuous -e.g. an operational amplifier. Nearly everyone who uses + and - voltages
will have a common load from V+ to V-I .
3. Vin + and Vin+ are not applied at the same time.

The above conditions result in one of the two outputs becoming reverse-biased which prevents
the regulator from turning "on". Latch-up can be prevented by the circuit configurations
shown in Figure 29 and 30.

PARTS LIST
Component

There is a general tendency to consider a voltage regulator
as simply a de circuit and to prepare circuit layout accordingly.

The excellent high-frequency performance and fast response capability of this integrated-circuit regulator, however, makes extra

layout care worthwhile. Since short, well-dressed leads must be
used, printed-circuit boards provide an excellent component inter-

connectJon technique.
The circuit layout, shown in Figure 31 for the "Roo or power
package IC, applies also to the lower power "G" package circuit
shown in Figure 32. The R package circuits will deliver up to 500
rnA into a load and the G package, 200 rnA.
The circuit schematic, Figure 33, is for output voltages above
3.5 Vdc and the parts list is as follows:

7. Remote Sensing
The connection to pin 8 can be made with a separate lead
direct to the load. Thus, "remote sensing" can be achieved
and the effect of undesired impedances (including that of
the milliammeter used to measure I L) on Zo can be gre,atly
reduced (see Figure 33).

THEORY OF OPERATION

is exactly the same approach used in the first option. That
is, the output is being resistively divided to match the
reference voltage. There is however, one big difference in
that the output of this "regulator" is driving the input of
another regulator (the error amplifier). The output of the
reference amplifier has a relatively low impedance as compared to the input impedance of the error amplifier.
Changes in the load of the output of the error amplifier
are buffered to the extent that they have virtually no effect
on the reference amplifier. If the feedback resistors are
external (as they are on the MC 1563) a wide range of
reference voltages can be established.
The error amplifier can now be operated at unity gain
to provide excellent regulation. In fact, this "regulatorwithin-a-regulator" concept permits the load regulation to
be specified in terms of output impedance rather than as
some percentage change of the output voltage. This approach was used in the design of the MC1563 negative
voltage regulator.

The usual series voltage regulator shown in Figure 23,
consists of a reference voltage, an error amplifier, and a
series control element. The error amplifier compares the
output voltage with the reference voltage and adjusts the
output accordingly until the error is essentially zero. For
applications requiring output voltages larger than the reference, there are two options. The first is to use a resistive
divider across the output and compare only a fraction of
the output voltage to the reference. This approach suffers
from reduced feedback to the error amplifier due to the
attenuation of the resistive divider. This degrades load
regulation especially at high voltage levels.
The alternative is to eliminate the resistive divider and
to shift the reference voltage instead. To accomplish this,
another amplifier is employed to amplify (or level shift)
the reference voltage using an operational amplifier as
shown in Figure 24. The gain-determining resistors may
be external, enabling a wide range of output voltages. This

input voltage. It makes use of two zener diodes having
the same breakdown voltage. A first or auxiliary zener is
driven directly from the input voltage line through a
resistor (60 kn) and permits the regulator to initially
achieve the desired bias conditions. This permits the
second, or reference zener to be driven from a current
source. When the reference zener enters breakdown, the
auxiliary zener is isolated from the rest of the regulator
circuitry by a diode disconnect technique. This is necessary
to keep the added noise and ripple of the auxiliary zener
from degrading the performance of the regulator.

Figure 25 shows the MC1563 (MC1463) Negative Regulator block diagram, simplified schematic, and complete
schematic. The four basic sections of the regulator are:
Control, Bias, DC Level Shift, and Output (unity gain)
Regulator. Each section is detailed in the following paragraphs.
Control
The control section involves two basic functions, startup and shutdown. A start-up function is required since
the biasing is essentially independent of the unregulated

(MC1563 - Pg. 8)

8-330

MC1563, MC1463 (continued)

The shutdown control, in effect, consists of a PNP transistor across the reference zener diode. When this transistor
is turned "ON", via pin 2, the reference voltage is reduced to
essentially zero volts and the regulator is forced to shutdown. During shutdown the current drain of the complete IC regulator drops to Vin/60 kn or 500 fJA for a
-30 V input.

inverting input to this amplifier is the Output Sense connection (pin 8) of the regulator. A Darlington connected
NPN power transistor is used to handle the load current.
The short-circuit current limiting resistor, Rsc, is connected in the emitter of this transistor to sample the full
load current. This connection enables a four-diode string
to limit the drive current to the power transistors in a
conventional manner.
Stability and Compensation

Bias
A zener diode is the main reference element and forms
the heart of the bias circuitry. Its positive temperature
coefficient is balanced by the negative temperature coefficients of forward biased diodes in a ratio determined
by the resistors in the diode string. The result is a reference voltage of approximately -3.5 Vdc with a typical
temperature coefficient of 0.002%/oC. In addition, this
circuit also provides a reference current which is used to
bias all current sources in the remaining regulator circuitry.

As has been seen, the MC 1563 employs two amplifiers,
each using negative feedback. This implies the possibility
of frequency instability due to excessive phase shift at high
frequencies. Since the error amplifier is normally used at
unity gain (the worst case for stability) a high impedance
node is brought out for compensation. For normal operation, a capacitor is connected between this point (pin 7)
and pin 5. The recommended value of 0.001 fJF will insure
stability and still provide acceptable transient response
(see Figure 21). It is also necessary to use an output capacitor, Co, (typically 10 fJF) directly from the output (pin
6) to ground. When an external transistor is used to boost
the current, Co = 100 fJF is recommended (see Figure 26).

DC Level Shift
The reference voltage is used as the input to a Darlington
differential amplifier. The gain of this amplifier is quite
high and it therefore may be considered to function as a
conventional operational amplifier. Consequently, negative
feedback can be employed using two external resistors (RA
and RB) to set the closed-loop gain and to boost the reference voltage to the desired output voltage. A capacitor,
Cn , is introduced externally into the level shift network
(via pin 3) to stabilize the amplifier and to filter the zener
noise. The recommended value for this capacitor is 0.1 fJF
and should have a voltage rating in excess of the desired
output voltage. Smaller capacitors (0.001 fJF minimum)
may be used but will cause a slight increase in output
noise. Larger values of Cn will reduce the noise as well as
delay the start-up of the regulator.

NPN CURRENT BOOSTING
For applications requiring more than 500 rnA of load
current, or for minimizing voltage variations due to temperature changes in the IC regulator arising from changes
of the internal power dissipation, the NPN current-boost
circuits of Figure 2 or 26, are recommended. The circuit
shown in Figure 26 can supply up to approximately 4.0
amperes (subject to safe area limitations). At higher currents the VBE of the pass transistor may itself exceed the
threshold of the current limit even for Rsc -= O. Figure 2
illustrates the use of an additional external diode from pin
4 for higher current operation or for pass transistors exhibiting higher VSE'S. It will probably be necessary to
determine Rsc experimentally for each case where a pass
transistor is used because VBE varies from device to device.

Output Regulator
The output of the shift amplifier is fed internally to the
noninverting input of the output error amplifier. The

(RA = 13 kn) supply and operating with a -15 V input,
with a Rsc of 0.1 .0, will yield a change in O!ltput voltage
of only 26 mV over a load current range of from I rnA
to 3.5 A. This corresponds to a dc output impedance
of only 7.5 milliohms or a percentage load regulation of
0.26% for a fuIl3.s-ampere load current change. Figure 27
indicates how the short circuit current varies with the value
of Rsc for this circuit.

28 this represents a savings of 22 watts when compared
with operating the regulator from the single -9 V supply.
It can supply current to 10 amperes while requiring an
input voltage to the collector of the pass transistor of -6.8
volts minimum. The pass transistor is limited to 10 amperes
by the added short-circuit current network in its emitter
(Rsc2) and the IC regulator is limited to 500 rnA in the
conventional manner (Rsc1). The MJ4s0 exhibits a minimum hFE of 20 at 10 amperes, thus requiring only 500
rnA from the MCls63R. Regulation of this circuit is comparable to that of the NPN boost configuration.
For higher output voltages the additional unregulated
power supply is not required. The collector of the PNP
boost transistor can tie directly to pin 5 and the internal
current limit circuit will provide short-circuit protection
using Rsc (see Figure II). Transistor Q2 and Rsc2 will
not be required and pin 2 should be returned to ground.

PNP CURRENT BOOSTING
A PNP power transistor can also be used to boost the
load current capabilities. To improve the efficiency of the
PNP boost configuration, particularly for small output
voltages, the circuit of Figure 28, is recommended. An
auxiliary -9 volt supply is used to power the IC regulator
and the heavy load current is obtained from a second supply
of lower voltage. For the 10-ampere regulator of Figure

less than 0.1 mV over a zero to -300 mAdc current range
and the + IS-volt supply tracks this variation. The + 15-volt
supply varies 20 mV over the zero to +300-mAdc load
current range. The +5-volt supply varies less than 5 mV
for 0 .;;; IL .;;; 200 rnA with the other two voltages remaining unchanged. See MCI561 data sheet or MCI569 data
sheet for information concerning latch-up when using plus
and minus regulations.

If the MCI563 is driven from a floating source it is
possible to use it as a positive regulator by grounding the
negative output terminal. The MCI563 may also be used
with the MCI569 to provide completely independent
positive and negative power regulators with comparable
performance. When used in this manner a silicon diode
such as the I N400 I must be connected as a clamp on the
output with the cathode to ground and the anode to the
negative output voltage. This is to prevent the positive
voltage in the system from forcing the output to a positive
value and preventing the MCI563 from starting up.
Some applications may require complementary tracking
in which both supplies arrive at the voltage level simultaneously, and variations in the magnitudes of the two voltages track. Figures 3 and 29 illustrate this approach. In
this application, the MCI563 is used as the reference regulator, establishing the negative output voltage. The MCI 569
positive regulator is used in a tracking mode by grounding
one side of the differential amplifier (pin 6 of the MC 1569)
and using the other side (pin 5 of the MC1569) to sense
the voltage developed at the junction of the two 3 k-ohm
resistors. This differential amplifier controls.the MCI569
series pass transistor such that the voltage at pin 5 will be
zero. When the voltage at pin 5 equals zero, + IVo I must
equal-IVol·
For the configuration shown in Figure 29, the level
shift amplifier in the MC 1569 is employed to generate an
auxiliary +5-volt supply which is boosted to a 2-ampere
capability by QI and Q2. (The +5-volt supply, as shown,

SHUTDOWN TECHNIQUES
Pin 2 of the MC 1563 is provided for the express purpose of shutting the regulator "OFF". Referring to the
schematic, it can be seen that pin 2 goes to the base of a
PNP transistor; which, if turned "ON", will deny current
to all the biasing current sources. This action causes the
output to go to essentially zero volts and the only current
drawn by the IC regulator will be the small start current
through the 60 k-ohm start resistor (Vin/60 kn). This
feature provides additional versatility in the applications
of the MC1563. Various sub-systems may be placed in a
"standby" mode to conserve power until actually needed.
Or the power may be turned "OFF" in response to other
occurrences such as over-heating, over-voltage, shorted
output, etc.
As an illustration of the first case, consider a system
consisting of both positive-supply logic (MTTL) and
negative-supply logic (MECL). The MECL logic may be
used in a high-speed arithmetic processor whose services
are not continuously required. Substantial power may

thus be conserved if the MECL circuitry remains un·
powered except when needed. The negative regulator can
be shutdown using any of the standard logic swings. For
saturated logic control, Figure 30 shows a circuit that allows
the normal positive output swing to cause the regulator
to shutdown when the logic output is in the low voltage
state. The negative output levels of a MECL gate can also
be used for shutdown control as shown in Figure 31.

A reduced input voltage can be provided by using a separate
supply. The output voltage may be zener-level shifted, and
the sense line can tie to a portion of the output voltage
through a resistive divider. The voltage boost circuit of
Figure 32 uses this approach to provide a -90 volt supply.
This circuit will exhibit regulation of 0.001 %over a 100 rnA
load current range.

VOLTAGE BOOSTING

The MCI563 offers a remote sensing capability. This
is important when the load is remote from the regulator,
as the resistances of the interconnecting lines (VEE and
GND) are added directly to the output impedance of the
regulator. By remote sensing, this resistance is included
inside the control loop of the regulator and is essentially
eliminated. Figure 33 shows how remote sensing is accomplished using both a separate sense line from pin 8 and a
separate ground line from the regulator to the remote load.

REMOTE SENSING

Some applications may require a high output voltage
which may exceed the voltage rating of the MC1563. This
must be solved by assuring that the IC regulator is operated
within its limits. Three points in the regulator need to
be considered:

1. The input voltage (pin 4),
2. the output voltage (pin 6) and,
3. the output sense lead (pin 8).

1O-3y/oC). By setting -0.61 Ydc externally, at pin 2, the
regulator will shutdown when the chip temperature reaches
approximately 1400 C. Figure 35 shows a circuit that uses
a zero-TC zener diode and a resistive divider to obtain
this vol tage.
In the case where an external pass transistor is employed;
its temperature, rather than that of the IC regulato(-, requires controL A technique similar to the one just discussed can be used by directly monitoring the case temperature of the pass transistor as is indicated in Figure 36.
The case of the normally "OFF" thermal monitoring
transistor, Q2, should be in thermal contact with, but
electrically isolated from, the case of the boost transistor, QI.

The MC1563, when used in conjunction with 10w·TC
resistors, makes an excellent reference-voltage generator.
If the -3.5 volt reference voltage of the IC regulator is a
satisfactory. value, then pins 1 and 9 can be tied together
and no resistors are needed. This will provide a voltage
reference having a typical temperature coefficient of
0.002%/oC. By adding two resistors, RA and RB, any
voltage between -3.5 Ydc and -37 Ydc can be obtained
with the same low TC (see Figure 34)
THERMAL SHUTDOWN
By setting a fixed voltage at pin 2, the MCl563 chip
can be protected against excessive junction temperatures
caused by power dissipation in the IC regulator. This is
based on the negative temperature coefficient of the
base-emitter junction of the shutdown transistor (-1.9 x

THERMAL CONSIDERATIONS
Monolithic voltage regulators are subjected to internal
heating similar to a power transistor. Since the degree of
internal heating is a function of the specific application,

the designer must use caution not to exceed the specified
maximum junction temperature (+ 17 SOC). Exceeding this
limit will reduce reliability at an exponential rate. Good
heatsinking not only reduces the junction temperature for
a given power dissipation; it also tends to improve the dc
stability of the output voltage by reducing the junction
temperature change resulting from a change in the power
dissipation ofthe IC regulator. By using the derating factors
or thermal resistance values given in the Maximum Ratings
Table of this data sheet, junction temperature can be com·
puted for any given application in the same manner as for
a power transistor *. A short·circuit on the output terminal
can produce a "worst-case" thermal condition especially
if the maximum input voltage is applied simultaneously
with the maximum value of short-circuit load current
(500 mA). Care should be taken not to exceed the maximum junction temperature rating during this fault condition and, in addition, the dc safe operating area limit (see
Figure 22).
Thermal characteristics for a voltage regulator are useful
in predicting performance since dc load and line regulation
are affected by changes in junction temperature. These
temperature changes can result from either a change in
the ambient temperature, TA, or a change in the power
dissipated in the IC regulator. The effects of ambient

temperature change on the dc output voltage can be estimated from the "Temperature Coefficient of Output
Voltage" characteristic parameter shown as ±0.002%/oC,
typical. Power disSipation is typically changed in the IC
regulator by varying the dc load current. To estimate the
dc change in output voltage due to a change in the dc load
current, three effects must be considered:
I. junction temperature change due to the change in
the power dissipation
2. output voltage decrease due to the finite output
impedance of the control amplifier
3. thermal gradient on the IC chip.
A temperature differential does exist across a power IC
chip and can cause a dc shift in the output voltage. A
"gradient coefficient," GCVO, can be used to describe this
effect and is typically +0.03%/watt for the MC1563R. For
an example of the relative magnitudes of these effects,
consider the following conditions:

THEORY OF OPERATION

yields a good working PNP from a lateral device working
at a collector current of only a few microamperes. Its base
vol tage (V B2) is derived from a temperature compensated
portion of the diode string and consequently the overall
current is dependent on the value of emitter resistor RI.
Temperature compensation of the base emitter junction
of Q3 is not important because approximately 9 volts
exists between VB2 and V12, making the AVBE's very
small in percentage. Circuit reference voltage is derived
from the product of IR and RR; if IR is set at I mA
(R! = 8.5 Hl.), then RR (in kn) = Yo. Other values of
current may be used as long as the following restraints are
kept in mind: I) package dissipation will be increased by
about 11 mW/mA and 2) bias current for the voltage control
amplifier is 3 /lA, temperature dependent, and is extracted
from the reference current. The reference current should

The schematic of Figure 5 can be simplified by break·
ing it down into basic functions, beginning with a simplified
version of the voltage reference, Figure 7. Zener diodes
CRI and CR5 with their associated forward biased diodes
CR2 through CR4 and CR6 through CR8 form the stable
reference needed to balance the differential amplifier. At
balance (VB! = VB2), the output voltage, (V12 - V7),
is at a value that is twice the drop across either of the two
diode strings: V12 - V7 = 2 (VCRI + VCR2 + VCR3 +
VCR4). Other voltages, temperature compensated or otherwise, are also derived from these diodes strings for use in
other parts of the circuit.
The voltage controlled current source (Figure 8) is a
PNP-NPN composite which, due to the high NPN beta,

~~--~---------

Loop amplification in the constant voltage mode is
supplied by the voltage controlled amplifier (Figure 9), a
standard high-gain differential amplifier_ The inputs are
diode-protected against differential overvoltages and an
emitter degenerating resistor, Ros, has been added to one
of the transistors. For an emitter current in both QS and
Q6 of 1/2 milliampere there will exist a preset offset voltage in this differential amplifier of 15mV to insure that
the output voltage will be zero when the reference voltage
is zero. Without ROS, the output voltage could be a few
millivolts above zero due to the inherent offset. Since the
load resistor is so large in this stage compared with the
load (Q9) it will be more instructive to look at the gain on
a transconductance basis rather than voltage gain. Transconductance of the differential stage is defined for small
signals as:

This level is further boosted by the output stage such that
in the constant voltage mode overall transconductance is
about 300 rnA/volt.
A second differential stage nearly identical to the first
stage, serves as the current control amplifier (Figure 10).
The gain of this stage insures a rapid crossover from the
constant voltage to constant current modes and provides
a convenient point to control the maximum deliverable
load current. In use, a reference voltage derived from the
pre regulator and a voltage divider is applied to pin 10
while the output current is sampled across RS by pin II.
When IL RS is IS mV below the reference value, voltage
V I begins. to rapidly rise, eventually gaining complete
control of Q9 and limiting output current to a value of
V2/RS. If V2 is derived from a variable source, short
circuit current may be controlled over the complete output current capability of the regulator. Since the constantvoltage to constant-current change-over requires only a few
millivolts the voltage regulation maintains its quality to
the current limit and accordingly shows a very sharp
"knee" (1% +1 rnA, Figure 11). Note that the regulator
can switch back into the constant voltage mode if the
output voltage reaches a value greater than YR. Operation
through zero milliamperes is guaranteed by the inclusion
of another emitter offsetting resistor.

Transistor Q9 and five diodes comprise the essential
parts of the output stage (Figure 12). The diodes perform
an "OR" function which allows only one mode of operation
at a time - constant current or constant voltage. However,
an additional stage (Q9) must be included to invert the
logic and make it compatible with the driving requirements
of series pass transistors as well as provide additional gain.
A 1.5 rnA collector current source sets the maximum deliverable output current and boosts the output impedance
to that of the current source.
Note that the negative (substrate) side of the MC1566/
MCI466 is 7.25 volts lower than the output voltage, and
the reference regulator guarantees that the positive side is
II volts above the output. Thus the IC remains at a voltage
(relative to ground) solely dependent on the output, "floating" above and below Vo. VCE across Q9 is only two or
three VBE's depending on the number of transistors used
in the series pass configuration.
Performance characteristics of the regulator may be
approximately calculated for a given circuit (Figure 2).
Assuming that the two added transistors (Q12 and Q13)
have minimum beta's of 20, then the overall regulator
transconductance will be:
gmT = (400)300 rnA/volt = 120 A/volt.

For a change in current of 500 rnA the output voltage
will drop only:

C:~:';I ~~:I~~er

The analysis thus far does not consider changes in VR
due to output current changes. IfIL increases by 500 rnA
the collector current of Q9 decreases by 1.25 rnA, causing
the collector current of Q5 to increase by 30 p.A. Accordingly, IR will be decreased by ~.30 p.A which will drop
the output by 0.03%. This figure may be improved considerably by either using higil beta devices as the pass
transistors, or by increasing IR. Note again, however, that
the maximum power rating of the package must be kept
in mind. For example if IR = 4 rnA, power dissipation is
PD = 20 V (8 rnA) + (II V x 3 rnA) = 193 mW. (5)
This indicates that the circuit may be safely operated up
to 1180 C using 20 volts at the auxiliary supply voltage.
If, however, the auxiliary supply voltage is 35 volts,
PD =35 V (8 rnA) + 26 V (3 rnA) =358 mW.

(6)

which dictates that the maximum operating temperature
must be less than 91 0 C to keep package dissipation within
specified limits.
Line voltage regulation is also a function of the voltage
change between pins 8 and 9, and the change of Vref. In
this case, however, these voltages change due to changes in
the internal regulator's voltages, which in turn are caused
by changes in Vaux . Note that line voltage regulation is
not a function of Yin. Note also that the instantaneous
value of Vaux must always be between 20 and 35 volts.
Figure 6 shows six external diodes (CRI to CR6) added
for protective purposes. CRI should be used if the output
voltage is less than 20 volts and CR2, CR3 are absent. For
Vo hig11er than 20 volts, CRI should be discarded in favor
of CR2 and CR3. Diode CR4 prevents IC failure if the
series pass transistors develop collector-base shorts while
the main power transistor suffers a simultaneous open emitter. If the possibility of such a transistor failure mode
seems remote, CR4 may be deleted. To prevent instantaneous differential and common-mode breakdown of the
current sense amplifier, CR5 must be placed across the
current limit resistor Rs.
Load transients occasionally produce a damaging reversal
of current flow from output to input Vo > 150 volts (which
will destroy the IC). Diode CR6 prevents such reversal
and renders the circuit immune from destruction for such
conditions, e.g., adding a large output capacitor after the
supply is turned "on". Diodes CRI, CR2, CR3, and CR5
may be general purpose silicon units such as I N400 I or
equivalent whereas CR4 and CR6 should have a peak inverse
voltage rating equal to Vin or greater.

Figure 2 shows a typical O-to-40 volts, 0.5-ampere regulator with better than 0.01% performance, The RC network between pins 5 and 6 and the capacitor between pins
13 and 14 provide frequency compensation for the MC1566/
MC1466. The external pass transistors are used to boost
load current, since the output current of the regulator is
less than 2 rnA.

Figure I is a 0-to-15 volts, IO-ampere regulator with the
pass transistor configuration necessary to boost the load
currentto 10 amperes. Note that Co has been increased to
1000 p.F following the general rule:

tible with a short-circuit current of 100 mAo Yet current
foldback allows us to design for a maximum regulated load
current of 500 mAo The pertinent design equations are:

The prime advantage of the MC1566/MC1466 is its use
as a high voltage regulator, as shown in Figure 3. This
0-to-250 volts OJ-ampere regulator is typical of high voltage applications, limited only by the breakdown and safe
areas of the output pass transistors.

The primary limiting factor in high voltage series regulators is the pass transistor. Figure 13 shows a safe area curve
for the MJ413. Looking at Figure 3, we see that if the
output is shorted, the transistor will have a collector current of 100 mA, with a VCE approximately equal to 260
volts. Thus this point falls on the dc line of the safe area
curve, insuring that the transistor will not enter secondary
breakdown.

In this respect (Safe Operating Area) the foldback circuit
of Figure 14 is superior for handling high voltages and yet
is short-circuit protected. This is due to the fact that load
current is diminished as output voltage drops (VCE increases
as V0 drops) as seen in Figure IS. By careful design the
load current at a short, ISC can be made low enough such
that the combined VCE (Vin) and ISC still falls within the
dc safe operating area of the transistor. For the illustrated
design (Figure· 14), an input voltage of 210 volts is compa-

from hundreds to thousands of volts in magnitude and only
microseconds in duration. Under some conditions this energy is dissipated across the internal zener connected between pins 9 and 7. This transient condition may produce
a total failure of the regulator device without any apparent
explanation. This type of failure is identified by absence
of the 7-volt zener (CRI) between pin 9 and pin 7. To prevent this failure mode, two solutions have been successfully
applied. The first method involves the use of an external
zener and resistor that shunt more of the transient energy
around the IC (Figure 17). The second method is a transient suppression network consisting of capacitors that
equalize high frequency components across both the auxiliary and main supply. Figure IS illustrates the use of five
capacitors for the full wave rectified main supply and
Figure 19 uses six capacitors when a full wave bridge is used.

The terms ISC and Ik correspond to the short-circuit
current and maximum available load current as shown in
Figure IS.

VOLTAGE/CURRENT - MODE INDICATOR

There may be times when it is desirable to know when
the MCIS66/MCI466 is in the constant current mode or
constant voltage mode. A mode indicator can be easily
added to provide this feature. Figure 20 shows how a PNP
transistor has replaced a protection doide between pins S
and 9 of Figure 2. When the MC I S66/MC 1466 goes from
constant voltage mode to constant current mode, Vo will
drop below Vs and the PNP transistor will turn on. The
I-rnA current supplied by pin S will now be shunted to
ground through RI in parallel with R2, which provides a
control voltage, VC. This voltage Vc can then control a
Schmitt trigger which drives front panel lamps to indicate
"constant current" or "constant voltage."

10 • OUTPUT CURRENT (mAde)

Figure 16 shows a remote sense application which should
be used when high current or long wire lengths are used.

This type of wiring is recommended for any application
where the best possible regulation is desired. Since the
sense lines draw only a small current, large voltage drops
do not destroy the excellent regulation of the MC I S66/
MC1466.

GENERAL DESIGN INFORMATION
1. Output Voltage, Vo
.
a) For VO;;' 3.5 Vdc - Output voltage is set by resistors Rl
and R2 (see Figure 4). Set R2 = 6.8 k ohms and determine
Rl from the graph of Figure 10 or from the equation:
Rl"'( 2VO-71kn

7. Remote Sensina
The connection to pin 5 can be made with a separate lead
direct to the load. Thus, "remote sensing" can be achieved
and the effect of undesired impedances (including that of
the milliammeter used to measure IL) on Zo can be greatly
reduced (see Figure 37).

b) For 2.5 ".; Vo ".; 3.5 Vdc - Output voltage is set by resis·
tors Rl and R2 (see Figure 5), Resistors Rl and R2 can be

FIGURE 10 - R1 versus Vo
(VO;;' 3.5 Vdc, See Figure 4)

determined from the graph of Figure 11 or from the

equations:

c) Output voltage, VO. is determined by the ratio of Rl and
R2. therefore optimum temperature performance can be
achieved if R 1 and R2 have the same temperature
coefficient.
d) Output voltage can be varied by making Rl adjustable as

e) If Vo = 3.5 Vdc (to supply MRTt.:'for example). tie pins 6,
8 and 9 together. Rl and R2 are not needed in this case.
2. Short Circuit Current, Isc

valid when current is boosted as shown in Figures 2, 29 and
30.
3. Compensation, C c
A O.OOlIJF capacitor, C e • from pin 4 to ground will provide
adequate compensation in most applications, with or without current boost. Smaller values of C c will reduce stability
and larger vaJues of Cc will degrade pulse response and output impedance versus frequency. The physical location of
Cc should be close to the MC1569/MC1469 with short lead
lengths.
4. Noise Filter Capacitor, CN
A 0.1 /J.F capacitor, CN, from pin 7 to ground will typically
reduce the output noise voltage to 150 /J.V(rms). The value
of eN can be increased or decreased, depending on the
noise voltage requirements of a particular application. A
minimum value of 0.001 JlF is recommended.
5. Output Capacitor, Co
The value of Co should be at least 1.0 JlF in order to
provide good stability. The maximum value recommended
is a function of current limit resistor Rsc:

6. Shut·Down Control
One method of turning "OFF" the regulator is to apply a
dc voltage at pin 2. This control can be used to eliminate
power consumption by circuit loads which can be put in
"standby" mode. Examples include, an ac or dc "squelch"
control for communications circuits, and a dissipation control to protect the regulator under sustained output shortcircuiting (see Figures 34,39 and 40). As the magnitude of
the input·threshold voltage at Pin 2 depends directly upon
the junction temperature of the integrated circuit chip, a
fixed dc voltage at Pin 2 will cause automatic shut-down for
high junction temperatures (see Figure 391. This will protect the chip, independent of the heat sinking used, the am·
bient temperature, or the input or output voltage levels.
Standard logic levels of MRTL ,MDTL or MTTL can
also be used to turn the regulator "ON" or "OFF".

THEORY OF OPERATION
The usual series voltage regulator shown in Figure 25,
consists of a reference voltage, an error amplifier, and a
series control element. The error amplifier compares the
output voltage with the reference voltage and adjusts the
output accordingly until the error is essentially zero. For
applications requiring output voltages larger than the refer·
ence, there are two options. The first is to use a resistive
divider across the output and compare only a fraction of
the output voltage to the reference. This approach suffers
from reduced feedback to the error amplifier due to the
attenuation of the resistive divider. This degrades load
regulation especially at high voltage levels.
The alternative is to eliminate the resistive divider and
to shift the reference voltage instead. To accomplish this,
another amplifier is employed to amplify (or level shift)
the reference voltage using an operational amplifier as
shown in Figure 26. The gain·determining resistors may
be external, enabling a wide range of output voltages. This

FIGURE 25 - SERIES VOLTAGE REGULATOR

Thermal Shutdown
Thermal Considerations
Latch-Up

is exactly the same approach used in the first option. That
is, the. output is being resistively divided to match t;]C
reference voltage. There is however, one big difference l!l
that the output of this "regulator" is driving the input of
another regulator (the error amplifier). The output of the
reference amplifier has a relatively low impedance as compared to the input impedance of the error amplifier.
Changes in the load of the output of the error amplifier
are buffered to the extent that they have virtually no effect
on the reference amplifier. If the feedback resistors are
external (as they are on the MC15(9) a wide range of
reference voltages can be established.
The error amplifier can now be operated at unity gain
to provide excellent regulation. In fact, this "regulatorwithin·a·regulator" concept permits the load regulation to
be specified in terms of output impedance rather than as
some percentage change of the output voltage. T)'is approach was used in the design of the MC 1569 positive·
voltage regulator.

Mel 569 Operation
Figure 27 shows the MCl569 Regulator block diagram,
simplified schematic, and complete schematic. The four
basic sections of the regulator are: Control, Bias, DC
Level Shift, and Output (unity gain) Regulator. Each section is detailed in the following paragraphs.

Control
The control section involves two basic functions, startup and shutdown. A start-up function is required since
the biasing is essentially independent of the unregulated

input voltage. It makes use of two zener diodes having
the same breakdown voltage. A first or auxiliary zener is
driven directly from the input voltage line through a resistor (60 kr2) and permits the regulator to initially
achieve the desired bias conditions. This permits the
second, or reference zener to be driven from a current
source. When the reference zener enters breakdown, the
auxiliary zener is isolated from the rest of the regulator
circuitry by a diode disconnect technique. This is necessary to keep the added noise and ripple of the auxiliary
zener from degrading the performance of the regulator.

MC1569-Pg.8

8-362

MC1569, MC1469 (continued)

Output Regulator

The shutdown control consists of an NPN transistor
across the reference zener diode. When this transistor is
turned "ON", via pin 2, the reference voltage is reduced to
essentially zero volts and the regulator is forced to shutdown. During shutdown the current drain of the complete IC regulator drops to Vin/60 kn or 500 /lA for a
30 V input.

The output of the level shift amplifier (pin 9) is fed to
the noninverting input (pin 6) of the output error amplifier. The inverting input to this amplifier is. the Output
Sense connection (pin 5) of the regulator. A Darlington
connected NPN power transistor is used to handle the load
current. The short-circuit current limiting resistor, Rsc, is
connected in the emitter of this transistor to sample the
full load current. By placing an external low-level NPN
transistor. across Rsc as shown in Figure 27, output
current can be limited to a predetermined value:

Bias
A zener diode is the main reference element and forms
the heart of the bias circuitry. Its positive temperature
coefficient is balanced by the negative temperature coefficients of forward biased diodes in a ratio determined
by the resistors in the diode string. The result is a reference voltage of approximately 3.5 Vdc with a typical
temperature coefficient of 0.002 %/"C. In addition, this
circuit also provides a reference curren t which is used to
bias all current sources in the remaining regulator circuitry.

where IL max is the maximum load current (amperes) and
Rsc is the value of the current limiting resistor (ohms).

DC Level Shift

Stability and Compensation

The reference voltage is used as the input to a Darlington
differential amplifier. The gain of this amplifier is quite
high and it therefore may be considered to function as a
conventional operational amplifier. Consequently, negative
feedback can be employed using two exte mal resistors (R I
and R2) to set the closed-loop gain and to boost the reference voltage to the desired output voltage. A capacitor,
CN, is introduced externally into the level shift network
(via pin 7) to stabilize the amplifier and to filter the zener
noise. The recommended value for this capacitor is 0.1 /IF
and should have a voltage rating in excess of the desired
output voltage. Smaller capacitors (0.001 /IF minimum)
may be used but will cause a slight increase in output
noise. Larger values of CN will reduce the noise as well as
delay the start-up of the regulator.

As· has been seen, the MC 1569 employs two amplifiers,
each using negative feedback. This implies the possibility
of instability due to excessive phase shift at high frequencies. Since the error amplifier is normally used a t unity
gain (the worst case for stability) a high impedance node
is brought out for compensation. For normal operation, a
capacitor is connected between this point (pin 4) and
ground. The recommended value of 0.00 I /IF will insure
stability and still provide acceptable transient response
(see Figure 28, A and B). It is also necessary to use an
output capacitor, Co (typically 1.0 /IF) from the output,
YO, to ground. When an external transistor is used to
boost the current, Co ~ 1.0 /IF is also recommended (see
Figure 2).

boost configuration, particularly for small output
voltages, the circuit of Figure 29 is recommended. An
auxiliary 9.5-volt supply is used to power the IC regulator
and the heavy load current is obtained from a second
supply of lower voltage_ For the 5_0 ampere regulator of
Figure 29 this represents a savings of 17_5 watts when
compared with operating the regulator from the single 9.S
V supply_ It can supply current to 5_0 amperes while
requiring an inpu t voltage to the collector of the pass
transistor of 6.0 volts minimum_ The pass transistor is
limited to 5.0 amperes by the added short-circuit current
network in its emitter (Rsc), (Figure 29B)_

PNP CURRENT BOOSTING
A typical PNP current boost circuit is shown in Figure
30. Voltages from 2.5 Vdc to 37 Vdc and currents of
many amperes can be obtained with this circuit.
Since the PNP transistor must not be turned on by the
MC1569 bias current (lIB) the resistor Rin must meet the
following condition

where VBE is the base-to-emitter voltage required to turn
on the PNP pass transistor, (typically 0.6 Vdc for silicon
and 0.2 Vdc for germanium).
For germanium pass transistors, a silicon diode may be
placed in series with the emitter to provide an additional
voltage drop. This allows a larger value of Rin than would
be possible if the diode were omitted. The diode will,
however, be required to carry the maximum load current.

SELF-OSCILLATING SWITCHING
REGULATOR
In all of the current boosting circuits shown thus far it
has been assumed that the input-output voltage differential can be minimized to obtain maximum efficiency in
both the external pass element as well as the MC1569.
This may not be possible in applications where only a
single supply voltage is available and high current levels
preclude zener diode pre-regulating approaches. In such
applications a switching-mode voltage regulator is highly
desirable since the pass device is either ON or OFF. The
theoretical efficiency of an ideal switching regulator is
100%_ Realizable efficiencies of 90% are within the realm
of possibility thus obviating the need for large power dissipating components_ The output voltage will contain a
ripple component; however, this can be made quite small
if the switching frequency is made relatively high so filtering techniques are effective. Figure 31 shows a functional
diagram for a self-oscillating voltage regulator. The
comparator-driver will sense the voltage across the inductor, this voltage being related to the load current, IL, by

NPN CURRENT BOOSTING
For applications requiring more than 500 rnA of load
current, or for ~inimizing voltage variations due to temperature changes in the IC regulator arising from changes
of the internal power dissipation, the NPN current-boost
circuits of Figure 2 or 29 are recommended_ The transistor shown in Figure 29A, the 2N3055 can supply
currents to 5_0 amperes (subject, of course, to the safe
area Iimitations)_ To improve the efficiency of the NPN

Normally this frequency will be in the range of approximately 2 kHz to 6 kHz. In this range, inductor values can
be small and are compatible with the switching times of
the pass transistor and diode. The switching time of the
comparator is quite fast since positive feedback aids both
turn-on and turn-off times_ The limiting factors are the
diode and pass transistor rise and fall times which should
be quite fast or efficiency will suffer.
Figure 32 shows a self oScillating switching regulator
which in many respects is similar to the PNP curren t boost
previously discussed. The 6_8 kn resistor in conjunction
with RI sets the reference voltage, Vref. QI and CRI are
selected for fast switching times as well as the necessary
power dissipation ratings. Since a linear inductor is assumed, the inductor cannot be allowed to saturate at
maximum load currents and should be chosen accordingly.
If core saturation does occur, peak transistor and diode
currents will be large and power dissipation will increase.

can be adjusted to minimize the ripple component as well
as to trim the operating frequency. Also this frequency
will change with varying loads as is normal with this type

desired. Rsc should be set such that the ratio of load current to base drive current is 10: I in this case II .., 100 rnA

POSITIVE AND NEGATIVE POWER
SUPPLIES
If the MC 1569 is driven from a floating source it is
possible to use it as a negative regulator by grounding the
positive output terminal. The MCI569 may also be used
with the MCI563 to provide completely independent positive and negative voltage regulators with comparable
performance.
Some applications may require complementary tracking
iii which both supplies arrive at the voltage level simultaneously, and varia tions in the magnitudes of the two
voltages track. Figures 3 and 33 illustrate this approach.
In this application, the MCI563 is used as the reference
regulator, establishing the negative output voltage. The
MCI569 positive regulator is used in a tracking mode by
grounding one side of the differential amplifier (pin 6 of
the MC 1569) and using the other- side (pin 5 of the
MC 1569) to sense the voltage developed at the junction of
the two 3-k 0!Un resistors. This differential amplifier
controls the MCI569 series pass transistor such that the
voltage at pin 5 will be zero. When the voltage at pin 5
equals zero, +VO must equal I-VOl.
For the configuration shown in -Figure 33, the level
shift amplifier in_ the MCI569 is employed to generate an
auxiliary +5-volt supply which is- boosted to a 2-ampere
capability by QI and Q2. (The +5-volt supply, as shown,

zero volts and the only current drawn by the IC regulator
will be the small start current through the 60-k-ohm start
resistor (Vin/60 kn). This feature provides additional
versatility in the applications of the MCIS69. Various subsystems may be placed in a "standby" mode to conserve
power until actually needed. Or the power may be turned
"OFF" in response to other occurrences such as overheating, over-voltage, shorted output, etc.
To activate shutdown, one simply applies a potential
greater than two diode drops with a current capability of
I rnA. Note that if a hard supply (i.e., +3 V) is applied
directly to pin 2, the shutdown circuitry will be destroyed
since there is no inherent current limiting. Maximum
rating for the drive current into pin 2 is 10 rnA, while
I rnA is adequate for shutdown.

varies less than 0.1 mV over a zero to -300 mAdc current

SHUTDOWN TECHNIQUES
Pin 2 of the MClS69 is provided for the express purpose of shutting the regulator "OFF". Referring to the
schematic, it can be seen that pin 2 goes to the base of an
NPN transistor; which, if turned "ON", will turn the
zener "OFF" and deny current to all the biasing current
sources. This action causes the output to go to essentially

Figure 34 shows how the regulator can be controlled
by a logic gate. Here, it is assumed that the regulator
operates in its normal mode - as a positive regulator
referenced to ground - and that the logic gate is of the
saturating type, operating' from a positive supply to
ground. The high logic level should be greater than about
1.5 V and should source no more than 10 mA into pin 2.
The gate shown is of the MDTL type. MRTL and
MTTL can also be used as long as the drive current is
within safe limits (this is important when using MTTL,
where the output stage uses an active pull·up).
In some cases a regulator can be designed which can
handle the power dissipation resulting from normal opera·
tion but cannot safely dissipate the power' resulting from a
sustained short-circuit. The circuit of Figure 35 solves
this problem by shutting down the regulator when the
output is short·circuited.

The MCI569 has a maximum output voltage capability
of 37 volts which covers the bulk of the user requirements.
However, it is possible to obtain higher output voltages.
One such voltage boosting circuit is shown in Figure 36.
Since high voltage NPN silicon devices are readily
available, the only problem is the voltage limitations of the
MC 1569. This can be overcome by using voltage shift
techniques to limit the voltage to 35 volts across the
MC 1569 while referencing to a higher output voltage.
The zener diode in the base lead of the NPN device is
used to shift the output voltage of the MCI569 by approximately 75 volts to the desired high voltage level, in
this case 100 volts. Another voltage shift is accomplished
by the resistor divider on the output to accommodate the
required 25 volt reference to the MC 1569. The 2 kn
resistor is used to bias the zener diode so the current
through the 4.7 kn resistor can be controlled by the
MC1569. The IN4001 diode protects the MCI569 from
supplying load current under short circuit conditions and
Q2 serves to limit base current to Q I. For Rsc as shown,
the short circuit current will be approximately 100 mAo
In order to use a single supply voltage, Vin(2) can be
derived from Vin(I) with a zener diode, shunt pre·
regulator.
It can be seen that loop gain has been reduced by the
resistor divider and hence the closed loop bandwid th will
be less. This of course will result in a more stable system,
but regulator performance is degraded to some degree.

REMOTE SENSING
The MC 1569 offers a remote sensing capability. This
is important when the load is remote from the regulator,

MC1569-Pg. 14

8-368

MC1569, MC1469 (continued)

as the resistance of the interconnecting lines (VO and
GND) are added directly to the output impedance of the
regulator. By remote sensing, this resistance is included
inside the control loop of the regulator and is essentially
eliminated. Figure 37 shows how remote sensing is accomplished using both a separate sense line from pin 8 and a
separate ground line from the regulator to the remote
load.

reference having a typical temperature coefficient of
0.002%/oC. By adding two resistors, RI and R2, any
voltage between 3.5 Vdc and 37 Vdc can be obtained
with the same low TC (see Figure 38).

THERMAL SHUTDOWN
By setting a fixed voltage at pin 2, the MC 1569 chip
can be protected against excessive junction temperatures
caused by power dissipation in the IC regulator. This is
based on the negative temperature coefficient of the baseemitter junction of the shutdown transistor and the diode
in series with pin 2 (-3.4 x 1O-3V/°C). By setting 1.0
Vdc externally at pin 2, the regulator will shutdown when
the chip temperature reaches approximately +1400 C. Figure 39 shows a circuit that uses a zero-TC zener diode and
a resistive divider to obtain this voltage.

AN ADJUSTABLE ZERO-TEMPERATURECOEFFICIENT (O-TC) VOLTAGE
REFERENCE SOURCE.
The MC1569, when used in conjunction with low TC
resistors, makes an excellent reference-voltage generator. If the 3.5 volt reference voltage of the IC regulator is
a satisfactory value, then pins 8 and 9 can be tied together
and no resistors are needed. This will provide a voltage

this fault condition and, in additio'n, the dc safe operating
area limit (see Figure 41).
Thermal characteristics for a voltage regulator are useful in predicting performance since dc load and line
regulation are affected by changes in junction temperature.
These temperature changes can result from either a change
in the ambient temperature, TA, or a change in the power
dissipated in the IC regulatoL The eJfects of ambient temperature change on the dc outpu t voltage can be estimated from the "Temperature Coefficient of Output
Voltage" characteristic parameter shown as ±0.002%/oC,

regulator by varying the dc load current. To estimate the
de change in output voltage due to a change in the dc load
current, three effects must be considered:

THERMAL CONSIDERATIONS
Monolithic voltage regulators are subjected to internal
heating similar to a power transistor_ Sin'ce the degree of
internal heating is a function of the specific application,
the designer must use caution not to exceed the specified
maximum junction temperature (+ ISOOC). Exceeding
this limit will reduce reliability at an exponential rate.
Good heatsinking not only reduces the junction temperature for a given power dissipation; it also tends to improve
the dc stability of the output voltage by reducing the
junction tempera ture change resulting from a change in the
power dissipation of the IC regulator. By using the derating. factors or thermal resistance values given in the
Maximum Ratings Table of this data sheet, junction temperature can be computed for any given application in
the same manner as for a power transistor' _ A shortcircuit on the output terminal can produce a "worst-case"
thermal condition especially if the maximum input voltage
is applied simultaneously with the maximum value of
short-circuit load currenL Care should be taken not to

the power dissipation

3_ thermal gradient on the lC chip_
A temperature differential does exist across a power lC
chip and can cause a de shift in the output voltage_ A
"gradient coefficient," GCVO, can be used to describe this
effect and is typically -0_06%/watt for the MCIS69_ For
an example of the relative magnitudes of these effects,
consider the following conditions:

The regulator biases the entire MC1594 circuit making it
essentially independent of supply variation. It also provides
two convenient regulated supply voltages which can be used

at pin 2 is approximately +4.3 V while the regulated voltage
at pin 4 is approximately -4.3 V. For optimum temperature
stability of these regulated voltages, it is recommended that

The output current can be easily converted to an output
voltage by placing a load resistor RL from the output (pin

current-to-voltage converter (Figure 16). The result in both
circuits is that the output voltage is given by:

that the scale factor be exact, R L can be comprised of a
fixed resistor and a potentiometer as shown in Figure 16.
It should be pointed out that there is nothing magic about

The input offset adjustment potentiometers, P 1 and P2 will
be necessary for most applications where it is desirable to
take advantage of the multiplier's excellent linearity characteristics. Depending upon the particular application, some
of the potentiometers can be omitted (see Figures 17, 19,
22. 24 and 25),

setting the scale factor to 1110. This is merely a convenient
factor to use if the Vx and Vy input voltages are expected
to be large. say ±10 V. Obviously with Vx

= Vy = 10 V and

a scale factor of unity, the device could not hope to provide
a 100 V output, so the scale factor is set to 1/10 and provides
an output scaled down by a factor of ten. For many applications it may be desirable to set K = 1/2 or K = 1 or even
K = 100. This can be accomplished by adjusting RX. Ry
and R L appropriately.

2.5

Offset and Scale Factor Adjustment Procedure
The adjustment procedure for the circuit of Figure 16 is:

A. X I nput Offset

The selection of R L is arbitrary and can be chosen after
resistors RX and Ry are found. Note in Figure 16 that Ry

(a) connect oscillator (1 kHz, 5 Vpp sinewave) to the "V"
input (pin 9)

is 62 kn while RX is 30 kn. The reason for this is that the
"Y" side of the multiplier exhibits a second order nonlinearity whereas the "X" side exhibits a simple non-linearity.
By making the Ry resistor approximately twice the value
of the RX resistor, the linearity on both the "X" and "Y"
sides are made equal. The selection of the RX and RV
resistor values is dependent upon the expected amplitude of
Vx and Vv inputs. To maintain a specified linearity,
resistors RX and Ry should be selected according to the
following equations:

(b) connect "X" input (pin 10) to ground
(c) adjust X-offset potentiometer, P2 for an ac null at
the output

B. Y Input Offset
(a) connect oscillator (1 kHz, 5 Vpp sinewave) to the "X"
input Ipin 10)
(b) connect "V" input (pin 9) to ground
(c) adjust V-offset potentiometer, Pl for an ac null at
the output

C. Output Offset

RV ~ 6 Vv (max) in kH when Vv is in volts

(a) connect both "X" and "V" inputs to ground
(b) adjust output offset potentiometer,P3, until the output voltage V o , is zero volts de

For example, if the maximum input on the "X" side is
± 1 volt, resistor RX can be selected to be 3 kH, If the maximum input on the "Y" side is also ± 1 volt, then resistor
Ry can be selected to be 6 kn (6,2 kn nominal value), If a
scale factoraf K = 10 is desired, the load resistor is found to
be 47 kn. In this example, the multiplier provides a gain
of 20 dB.

(a) apply +10 Vdc to both the "X" and "Y" inputs
Ib) adjust P4 to achieve -10.00 V at the output
(c) apply -10 Vdc to both "X" and "Y" inputs and check
for Vo = -10.00 V

Operational Amplifier Selection

E. Repeat steps A through 0 as necessary.

The operational amplifier connection in Figure 16 is a simple
but extremely accurate current-to-voltage converter. The
output current of the multiplier flows through the feedback
resistor R L to provide a low impedance output voltage from
the op-ampL Since the offset current and bias currents of
the op-ampl. will cause errors in the output voltage, particularly with temperature, one with very low bias and offset currents is recommended. The MC1556/MC1456 or MC1741/
MC1741 C are excellent choices for this application.

The ability to accurately adjust the MC1594 is dependent
on the offset adjust potentiometers. Potentiometers should
be of the "infinite" resolution type rather than wirewound.
Fine adjustments in balanced-modulator applications may
require two potentiometers to provide "coarse" and "fine"
adjustment. Potentiometers should have low temperature
coefficients and be free from backlash.

Since the MC1594 is capable of operation at much higher
frequencies than the op-ampL, the frequency characteristics
of the circuit in Figure 16 will be primarily dependent upon
the op-ampl.
2.3

D. Scale Factor

2.6

While the MC1594 provides excellent performance in itself,
overall performance depends to a large degree on the quality
of the external components. Previous discussion shows the
direct dependence on RX, Ry, and RL and indirect dependence on R 1 (through '1), Any circuit subjected to temperature variations should be evaluated with these effects in mind,

Stability
The current-to-voltage converter mode is a most demanding
application for an operational amplifier. Loop gain is at its
maximum and the feedback resistor in conjunction with
stray or input capacitance at the multiplier output adds additional phase shift. It may therefore be necessary to add
(particularly in the case of internally compensated op-ampls.)
a small feedback capacitor to reduce loop gain at the higher
frequencies. A value of 10 pF in parallel with RL should be
adequate to insure stability over production and temperature
variations, etc.

2.7

Bias Currents
The MC1594 multiplier, like most linear IC's, requires a de
bias current into its input terminals. The device cannot be
capacitively coupled at the input without regard for this bias
current. If inputs Vx and Vy are able to supply the small bias
current (~0.5 IlA) resistors, R (Figure 16) can be omitted,
If the MC1594 is used in an ac mode of operation and
capacitive coupling is used the value of resistor R can be any
reasonable value up to 100 kil. For minimum noise and
optimum temperature performance, the value of resistor R
shou Id be as low as practical.

An externally compensated op-ampl. might be employed
using slightly heavier compensation than that recommended
for unity-gain operation.

Parasitic Oscillation
When long leads are used on the inputs, oscillation may occur.
In this event, an RC parasitic suppression network similar to
the ones shown in Figure 16 should be connected directly
to each input using short leads. The purpose of the network

The non-inverting input of the op-ampl. provides a convenient
point to adjust the output offset voltage, By connecting this
point to the wiper arm of a potentiometer (P3), the output

is to reduce the "Q" ofthe source-tuned circuits which cause
the oscillation.
Inabil ity to adjust the circuit to with in the specified accuracy

twice the value of the RX resistor, the zero associated with
the "V" input will occur at approximately one octave below
the lero associated with the "X" input. For RX = 30 kn and

may be an indication of oscillation.

3.

AC OPERATION

3.1

General

Ry == 62 kn. the zeros occur at 1.5 MHz for the "X" input
and 700 kHz for the "V" input. These two measured break-

points correspond to a shunt capacitance of about 3.5 pF.
Thus, for the circuit of Figure 17, the "X" input zero and
"Y" input zero will be at approximately 15 MHz and
7 MHz respectively.
It should be noted that the MC1594 multiplies in the time
domain, hence, its frequency response is found by means
of complex convolution in the frequency (Laplace) domain.
This means thatif the "X" input does not involve afrequency,
it is not necessary to consider the "X" side frequency
response in the output product. Likewise, for the "V" side.
Thus, for applications such as a wideband I inear AGe amplifier which has a dc voltage as one input, the multiplier frequency response has one zero and one pole. For applications
which involve an ac voltage on both the "X" and "V" side,
such as a balanced modulator, the product voltage response
will have two zeros and one pole, hence, peaking may be
present in the output.
From this brief discussion, it is evident that for ac applications; (1) the value of resistors AX, RV and RL should be
kept as small as possible to achieve maximum frequency
response, and (2) it is possible to select a load resistor R L
such that the dominant pole (RL, C{») cancels the input zero
(RX, 3.5 pF or Ry, 3.5 pF) to give a flat amplitude characteristic with frequency. This is shown in Figures 9 and 10.
Examination of the frequency characteristics of the "X"
and "~V"~ inputs will demonstrate that forwideband amplifier
applications, the best tradeoff with frequency response and
gain is achieved by using the "Y"input for the ac signal.
For ac applications requiring bandwidths greater than those
specified for the MC1594, two ot'1.er devices are recomFor modulator-demodulator applications, the
mended.
MC1596 may be used up to 100 MHz. For wideband multiplier applications, the MC1595 (using small collector loads
and ac coupling) can be used.

For ac operation, such as balanced modulation, frequency
doubler, AGC, etc" the op-ampl. will usually be omitted as
well as the output offset adjust potentiometer. The output
offset adjust potentiometer is omitted since the output will
normally be ae-coupled and the de voltage at the output is
of no concern providing it is close enough to zero volts that
it will not cause clipping in the output waveform. Figure 17

shows a typical ac multiplier circuit with a scale factor K~ 1.
Again, resistor RX and RV are chosen as outlined in the
previous section, with RL chosen to provide the required
scale factor.
The offset voltage then existing at the output will be equal to
the offset current times the load resistance. The output offset current of the MC1594 is typically 17 p.A and 35

maximum.

3.3

Slew·Rate
The MC1594 multiplier is not slew-rate limited in the ordinary sense that an op-ampt. is. Since all the signals in the
multiplier are currents and not voltages, there is no charging
and discharging of stray capacitors and thus no limitations
beyond the normal device limitations. However, it should
be noted that the quiescent current in the output transistors
is 0.5 mA and thus the maximum rate of change of the output voltage is limited by the output load capacitance by
the simple equation:

~A

Thus, the maximum output offset would be

about 160 mV.

3.2

The reason for this

increase in gain is due to the bypassing of RX and Ry at
high frequencies. Since the Ry resistor is approximately

Bandwidth

The bandwidth of the MC1594 is primarily determined by
two factors. First, the dominant pole will be determined by
the load resistor and the stray capacitance at the output
terminal. For the circuit shown in Figure 17, assuming a
total output capacitance (Co) of 10 pF, the 3 dB bandwidth
would be approximately 3,4 MHz. If the load resistor were
47 kn, the bandwidth would be approximately 340 kHz.
Secondly, a "zero" is present in the frequency response
characteristic for both the "x" and "Y" inputs which causes
the output signal to rise in amplitude at a 6 dBfoctave slope
at frequencies beyond the breakpoint of the "zero". The
"zero" is caused by the parasitic and substrate capacitance
which is related to resistors RX and Ry and the transistors
associated with them. The effect of these transmission

This can be improved if necessary by addition of an emitterfollower or other type of buffer.

Phase· Vector Error
All multipliers are subject to an error which is known as the
phase-vector error. This error is a phase error only and does
not contribute an amplitude error per se. The phase-vector

However, a more careful look at the multiplier's defining
equation will provide some useful information. The output

Square Root
A special case of the divide circuit in which the two inputs
to the multiplier are connected together results in the square
root function as indicated in Figure 22. This circuit too
may suffer from latch-up problems similar to those of the
divide circuit. No~e that only one polarity of input is allowed
and diode clamping (see Figure 23) protects against accidental
latch-up.
This circuit too, may be adjusted in the closed-loop mode:

of approximately 20 dB.

1. Set Vz = -0.01 Vdc and adjust P3 (output offset) for
Va = 0.316 Vdc.
2. Set Vz to -0.9 Vdc and adjust P2 ("X" adjust) for Vo =
+3 Vdc.
3. Set Vz to -10 Vdc and adjust P4 (gain adjust) for Vo =
+10 Vdc.

It is AGC'd through a 60 dB

dynamic range with the application of an AGe voltage from
o Vdc to 1 Vdc. The bandwidth of the amplifier is determined by the load resistor and output stray capacitance. For
this reason, an emitter-follower buffer has been added to
extend the bandwidth in excess of 1 MHz.

Notice that the resistor values for AX. Ry, and RL have
been modified. This has been done primarily to increase the
bandwidth by lowering the output impedance of the MC 1594
and then lowering RX and Ry to achieve a gain of 1. The
ec can be as large as 1 volt peak and 8m as high as 2 volts
peak. No output offset adjust is employed since we-are
interested only in the ac output components.
The input R's are used to supply bias current to the multiplier inputs as well as provide matching input impedance.

minimum ac output when ac (5 Vpp, 1 kHz) is applied to the

OPERATION AND APPLICATIONS INFORMATION

1. Theory of Operation

2.1.2 3 dB·Bandwidth and Phase Shift

The MC1595 (MC14951 is a monolithic. four-quadrant multi·
plier which.Qperat8s on the principle of variable transconductance.
The detailed theory of operation is covered in Application Note
AN·489, Analysis and Basic Operation of the MC1595. The result
of this, analysis is that the differential output current of the multiplier is given by

Bandwidth is primarily determined by the load resistors and
the stray multiplier output capacitance and lor the operational
amplifier used to level shift the output. If wideband operation
is desired, low value load resistors andlor a wideband operational
amplifier should be used. Stray output capacitance will depend
to a large extent on circuit layout.
Phase shift in the multiplier circuit results from two sources:
phase shift common to both X and Y channels (due to the load
resistor-output capacitance pole mentioned above) and relative
phase shift between X .and Y channels (due to differences in
transadmittance in the X and Y channels). If the input to output
phase shift ·is only 0.60 , the output product of two sine waves
will exhibit a vector error of 1 %. A 3 0 relative phase shift between Vx and Vy results in a vector error of 5%.

where fA and '8 are the currents into pins 14 and 2. respectively.
and Vx and Vy are the X and Y input voltages at the multiplier

input terminals.

2. Design Considerations

2.1.3 Maximum Input Voltage

2.1 General

VX(max). VY(max) maximum input voltages must be such
that:

The MC1595 (MC14951 permits the deSigner to tailor the

multiplier to· a specific application by ·proper selection of external components. External components may be selected to

VX(maxl <113 R y

optimize a given parameter (e.g. bandwidth) which may in turn

VY(max) <13 R y.

restrict another parameter (e.g. maximum output voltage swing).
Each important parameter is discussed in detail in the following
paragraphs.

Exceeding this value will drive one side of the input amplifier to
"cutoff" and cause non-linear operation.
Currents 13 and 113 are chosen at a convenient value (observing power dissipation limitation) between 0.5 mA and 2.0 rnA,
approximately 1.0 rnA. Then R X and Ry can be determined by
considering the input Signal handling requirements.

2.1.1 Linearity, Output Error, ERX or ERY
Linearity error is defined as the maximum deviation of output voltage from a straight line transfer function. I t is expressed
as error in percent of full scale (see figure below).

For VX(maxl = VY(maxl = 10 volts;
RX =

At T A = +250 C and 113 = 13 = 1 mA,

Linearity error may be measured by either of the following
methods:
1. Using an X - Y plotter with the circuit shown in Figure 5.
obtain plots for X and Y similar to the one shown above.
2. Use the circuit of Figure 4. This method nulls the level
shifted output of the multiplier with the original input.
The peak output of the null operational amplifier will be
equal to the error voltage, VE(maxl'
One source of linearity error can arise from large Signal nonlinearity in the X and Y -input differential amplifiers. To avoid
introducing error from this source, the emitter degeneration
resistors R X and Ry must be chosen large enough so that nonlinear base-emitter voltage variation can be ignored. Figures 17
and 18 show the error expected from this source as a function
of the values of RX and Ry with an operating current of 1.0 mA
in each sideofthe differential amplifiers O.e.,13 = 113 = 1.0 mAl.

n.

Therefore, with AX = Ry = 10 kfl the above assumption is valid.
Reference to Figure 19 will indicate limitations of VX(max) or
VY(maxl due to VI and V7' Exceeding these limits will cause
saturation or "cutoff" of the input transistors. See Step 4 of
Section 3 (General DeSign Procedure) for further details.
2.1.4 Maximum Output Voltage Swing
The maximum output voltage swing is dependent upon the
factors mentioned below and upon the particular circuit being
considered.
For Figure 20 the maximum output swing is dependent
upon V+ for positive swing and upon the voltage at pin 1 for
negative swing. The potential at pin 1 determines the quiescent level for transistors 05, aS, 07, and aS. This potential

If an operational amplifier is used for level shift, as shown
in Figure 21, the output swing (of the multiplier) is greatly
reduced. See Section 3 for further details.

should be related so that negative swing at pins 2 or 14 does
not saturate those transistors. See Section 3 for further information regarding selection of these potentials.

3. General Design Procedure
Selection of component values is best demonstrated by the

following example: assume resistive dividers are used at the X and

For dc applications, such as the multiply, divide and squareroot functions, it is usually desirable to convert the differential
output to a single-ended output voltage referenced to ground.
The circuit shown in Figure 22 performs this function. It can be
shown that the output voltage of this circuit is given by:

is sufficient.

4. Offset and Scale Factor Adjustment

Offset Voltages
Within the monolithic multiplier (Figure 3) transistor baseemitter junctions are typically matched within 1 mV and resistors

are typically matched within 2%. Even with this careful matching. an output error can occur. This output error is comprised
of X-input offset voltage, V-input offset voltage, and outputoffset voltage_ These errors can be adjusted to zero with the techniques shown in Figure 21. Offset terms can be shown analytically by the transfer function:

If well regulated supply voltages are available, the offset ad·
just circuit of Figure 13 is recommended. Otherwise, the circuit

4.2 Scale Factor
The scale factor, K, is set by P3(F igure 21). P3 varies 13 which

5.3 Divide Circuit
Consider the circuit shown in Figure 24 in which the multiplier is placed in the feedback path of an operational amplifier.
For this configuration, the operational amplifier will maintain
a "virtual ground" at the inverting (-I input. Assuming that the

5.1 Multiply
The circuit shown in Figure 21 may be used to multiply
signals from dc to 100 kHz. Input levels to the actual multiplier are 5.0 V (maxI. With resistive voltage dividers the maximum could be very large - however, for this application twoto-one dividers have been used so that the maximum input
level is 10V. The maximum output level has also been designed

Hence, the output voltage is the ratio of Vz to Vx and provides
adivide function. This analysis is, of course, the ideal condition.
If the multiplier error is taken into account, the output voltage
is found to be

From equation 7. the percentage error is inversely related to
voltage Vz (i.e., for increasing values of Vz. the percentage
error decreases).

Two things should be emphasized concerning Figure 25.
(S)

1. The input voltage (V'X) must be greater than zero and
must be positive. This insures that the current out of
pin 2 of the multiplier will always be in a direction com-

where ll.E is the error voltage at the output of the multiplier.

1. Set Vz = 0 volts and adjust the output offset potentiometer (P 4) until the output voltage (Va) remains at some

error voltage of the divide circuit as low as the error of the
multiply circuit. For example. when Vx is small. (0.1 volt)

A potted multiplier can be used to obtain the double frequency component, but frequency would be limited by its
internal level-shift amplifier. I n the monolithic units, the amplifier is om"itted"
I n a typical doubler circuit, conventional ± 15-volt supplies
are used. An input dynamic range of 5.0 volts peak-to-peak is
allowed. The circuit generates wave-forms that are double frequency; less than 1% distortion is encountered without filtering.
The configuration has been successfully used in excess of 200
kHz; reducing the scale factor by decreaSing the load resistors
can further expand the bandwidth.
A slightly modified version of the MC1595 (MC14951 the MC1596 (MC1496) - has been successfully used as a doubler
to obtain 400 MHz. (See Figure 28.1

1. Set Vz to - 0.01 volts and adjust P4 (output offset) for

6.4 Linear Gain Control
To obtain linear gain control, the deSigner can feed to one
of the two MC1595 (MCI495) inputs. Signal that will vary the
unit's gain. The following example demonstrates the feasibility
of this application. Suppose a 200 kHz sine wave, 1.0 volt
peak-to-peak, is the signal to which a gain control will be added.
The dynamic range of the control voltage Vc is 0 to +1.0 volt.
These must be ascertained and the proper values of AX and Ay
can be selected for optimum performance. For the 200-kHz
operating frequency, load resistors of 100 ohms were chosen to
broaden the operating bandwidth of the multiplier, but gain was
sacrificed. It may be made up with an amplifier operating at the
appropriate frequency. (See Figure 31,)

OPERATION AND APPLICATIONS INFORMATION (continued)

The signal is applied to the unit's Y input. Since the total
input range is limited to 1.0 volt pop, a 2.O-volt swing, a current
source of 2.0 mA and an Ry value of 1.0 kilohm Is chosen.
This takes best advantage of the dynamic range and insures
linear operation in the Y-channel.
Sin"" the X input varies between and +1.0 volt, the current
source selected was 1.0 mA and the RX value chosen was 2.0
kilohms. This also insures linear operation over the X input

GENERAL OPERATING INFORMATION *
Note 1 - Carrier Feodthrough

Carrier feedthrough is defined as the output voltage at carrier
frequency with only the carrier applied (signal voltage = 01.

Note 6 - Design Equations
The following is a partial list of design equations. needed to
operate the circuit with other supply voltages and input condi·
tions. See Note 3 for Ae equation.

A. Operating Current

Carrier suppression is defined as the ratio of each sideband output to carrier output for the carrier and signal voltage levels speci-

The internal bias currents are set by the conditions at pin 5.
Assume:

fied.
Carrier suppression is very dependent on carrier input level, as
shown in Figure 24. A low value of the carrier does not fully

15=16=19

switch the upper switching devices, and results in 1000er signal
gain, hence lower carrier suppression. A higher than optimum carrier level results in unnecessary device and circuit carrier feedthrough, which again degenerates the suppression figure. The
MC1596 has been characterized with a 60 mV(rmsl sinewave
carrier input signal. This level provides optimum carrier suppression at carrier frequencies in the vicinity of 500 kHz, and is
generally recommended for balanced modulator applications.
Carrier feedthrough is independent of signal level, VS. Thus
carrier suppression can be maximized by operating with large signal levels. However. a linear operating mode must be maintained
in the signal-input transistor pair - or harmonics of the mooulating
signal will be generated and appear in the device output as spurious
sidebands of the suppressed carrier. This requirement places an
upper limit on input-signal amplitude (see Note 3 and Figure 22).
Note also that an optimum carrier level is recommended in F igure 24 for good carrier suppression and minimum spurious sideband generation.
At higher frequencies circuit layout is very important in order
to minimize carrier feedthrough. Shielding may be necessary in
order to prevent capacitive coupling between the carrier input
leads and the output leads.

OPERATIONS INFORMATION

The MC1596/MC1496. a monolithic balanced modulator cir·
cuit, is shown in Figure 5.
This circuit consists of an upper quad differential amplifier
driven by a standard differential amplifier with dual current

sources. The output collectors are

cross~coupled

The linear signal handling capabilities of a differential amplifier
are well defined. With no emitter degeneration, the maximum
input voltage for linear operation is approximately 25 mV peak.
Since the upper differential amplifier has its emitters internally
connected, this voltage applies to the carrier input port for all
cond it io ns.
Since the lower differential amplifier has provisions for an
external emitter resistance, its linear Signal handling range may be
adjusted by the user. The maximum input voltage for linear operation may be approximated from the following expression:

so that full-wave

balanced multiplication of the two input voltages occurs. That is,

the output signal is a constant times the product of the two input
signals.
Mathematical analysis of linear ae signal multiplication indi-

cates that the output spectrum will consist of only the sum and
difference of the two input frequencies. Thus, the device may be
used as a balanced modulator, doubly balanced mixer, product
detector, frequency doubler, and other applications requiring
these particular output signal characteristics.
The lower differential amplifier has its emitters connected to
the package pins so that an external emitter resistance may be
used. Also, external load resistors are employed at the device
output.

V

=(15) (RE)VOItS peak.

This expression may be used to compute the minimum value of
RE for a given input voltage amplitude.

The upper quad differential amplifier may be operated either
in a linear or a saturated mode. The lower differential amplifier
is operated in a linear mode for most applications.
For low-level operation at both input ports, the output signal
will contain sum and difference frequency components and have
an amplitude which is a function of the product of the input signal
amplitudes.
For high-level operation at the carrier input port and linear
operation at the modulating signal port, the output signal will
contain sum and difference frequency components of the modulating Signal frequency and the fundamental and odd harmonics of
the carrier frequency. The output amplitude will be a constant
times the modulating signal amplitude. Any amplitude variations
in the carrier signal will not appear in the output.

The gain from the modulating signal input port to the output is
the MC1596/MC1496 gain parameter which is most often of interest
to the designer. This gain has significance only when the lower
differential amplifier is operated in a linear mode, but this includes
most applications of the device.
As previously mentioned, the upper quad differential amplifier
may be operated either in a linear or a saturated mode. Approximate gain expressions have been developed for the MC15961
MC1496 for a low-level modulating Signal input and the following
carrier input conditions:
1)
2)
3)
4)

Low·level dc
High-level dc
Low-level ac

These gains are summarized in Table 1, along with the frequency components contained in the output signal.

package'd device refer to the PIN CONNECTION CHART on the first page.of this specification.

APPLICATION INFORMATION

Double sideband suppressed carrier modulation is the basic
application of the MC1596/MC1496. The suggested circuit for
this application is shown on the front page of this data sheet.
In some applications, it may be necessary to operate the
MC1596/MC1496 with a single dc supply voltage instead of dual
supplies. Figure 26 shows a balanced modulator designed for
operation with a single +12 Vdc supply. Performance of this circuit is similar to that of the dual supply modulator.

carrier Signal at the carrier input and an AM signal at the SSB
input.
The carrier signal may be derived from the intermediate frequency Signal or generated locally. The carrier signa I may be introduced with or without modulation, provided its level is
sufficiently high to saturate the upper quad differential amplifier.
If the carrier signal is modulated, a 300 mV(rms) input level is
recommended.

AM Modulator

Doubly Balanced Mixer

The circuit shcwvn in Figure 27 may be used as an amplitude
modulator with a minor modification.
All that is required to shift from suppressed carrier to AM
operation is to adjust the carrier null potentiometer for the proper
amount of carrier insertion in the output signal.
However, the suppressed carrier null circuitry as shown in
Figure 27 does not have sufficient adjustment range. Therefore,
the modulator may be modified for AM operation by changing
two I1!sistor values in the null circuit as shown in Figure 28.

The MC1596/MC1496 may be used as a doubly balanced
mixer with either broadband or tuned narrow band input and
output networks.
The local oscillator signal is introduced at the carrier input
port with a recommended amplitude of 100 mV(rrns}.
Figure 30 shows a mixer with a broadband input and a tuned
output.

Product Detector
The MC1596/MC1496 makes an excellent SSB product detector (see Figure 291.
This product detector has a sensitivity of 3.0 microvolts and a
dynamic range of 90 dB when operating at an intermediate frequency of 9 MHz.
The detector is broadband for the entire high frequency range.
For operation at very low intermediate frequencies down to 50
kHz the 0.1 pF capacitors on pins 7 and 8 should be increased to
1.0 JJF. Also, the output filter at pin 9 can be tailored to a
specific intermediate frequency and audio amplifier input impedance.
As in all applications of the MC 1596/MC1496, the emitter
resistance between pins 2 and 3 may be increased or decreased to
adjust circuit gain, sensitivity, and dynamic range.
This circuit may also be used as an AM detector by introducing

Frequency Doubler
The MC1596/MC1496 will operate as a frequency doubler by
introducing the same frequency at both input ports.
Figures 31 and 32 show a broadband frequency doubler and a
tuned output .very high frequency (VHFI doubler, respectively.
Phase Detection and FM Detection
The MC1596/MC1496 will function as a phase detector. Highlevel input signals are introduced at both inputs. When both inputs
are at the same frequency the MC1596/MC1496 will deliver an
output which is a function of the phase difference between the
two input signals.
An FM detector may be constructed by using the phase detector principle. A tuned circuit is added at one of the inputs to
cause the two input signals to vary in phase as a function of frequency. The MC1596/MC1496 will then provide an output which
is a function of the input Signal frequency.

SETTLING TIM!: MEASUREMENT
In order to accurately measure the settling time of an
operational amplifier, it is suggested that the "false"
summing junction approach be taken as shown, in
Figure 11. This is necessary since it is difficult to determine when the waveform at the output of the operational amplifier settles to within 0.1 % of it's final
value. Because the output and input voltages are effectively subtracted from each other at the amplifier
inverting input, this seems like an ideal node for the
measurement. However, the probe capacitance at this
critical node can greatly affect the accuracy of the
actual measurement.
The solution to these problems is the creation of a
second or "false" summing node. The addition of two
diodes at this node clamps the error voltage to limit the
voltage excursion to the oscilloscope. Because of the
voltage divider effect, only one-half of the actual error
appears at this node. For extremely critical measurements, the capacitance of the diodes and the oscilloscope,
and the settling time of the oscilloscope must be considered. The expression

can be used to determine the actual amplifier settling

It should be remembered that to settle within ±0.1 %
requires 7RC time constants.
The ±O.l% factor yvas chosen for the MC1741S

accuracy of the MC150BL-B digital-to-analog converter.

SETTLING TIME
In order to properly utilize the high slew rate and fast
settling time of an operational amplifier, a number of
system considerations must be observed. Capacitance at
the summing node and at the amplifier output must be
minimal and circuit board layout should be consistent
with common high-frequency considerations. Both power
supply connections should be adequately bypassed as
close as possible to the device pins. In bypassing, both
low and high-frequency components should be considered to avoid the possibility of excessive ringing. In
order to achieve optimum damping, the selection of a
capacitor in parallel with the feedback resistor may be
necessary. A value too small could result in excessive
ringing while a value too large will degrade slew rate and
settling time.

Specifications and Applications InforIllation
MONOLITHIC MICROPOWER
PROGRAMMABLE OPERATIONAL AMPLIFIER
This extremely versatile operational amplifier features low-power
consumption, high input impedance and low input noise levels_ In
addition, the quiescent currents within the device may be programmed by the choice of an external resistor value or current source
applied to the Iset input_ This allows the amplifier's characteristics
to be optimized for input current, power consumption and input
voltage,and current noise despite wide variations in operating power
supply voltages_

NOTES:
1. The quiescent current drain will increase approximately 0.3
rnA for each inverting or non inverting input that is grounded.
2. Input bias current can be defined only fQr the inverting input.
The noninverting input is not a true "differential input" - as
with a conventional IC operational amplifier. As such this

PSSR

-

input does not have a requirement for input bias current.
3. Current mirror gain is defined as the current demanded at the
inverting input divided by the current into the non inverting
input.
4. Bandwidth and phase margin are defined with respect to the
voltage gain from the inverting input to the output.

linear operation at the output. The sink current of the device can
be forced to exceed the specified level by keeping the output de
voltage above:::::::: 1.0 volt resulting in an increase in the distortion

The basic ampl ifier is the common emitter stage shown in Figures
15 and 16. The active load '1 is buffered from the input transistor
by a PNP transistor, Q4, and from the output by an NPN transistor,
Q2. Q2 is biased class A by the current source '2. The magnitude
of '2 (specified 'sink) is a limiting factor in capacitively coupled

appearing at the output. Closed loop stability is maintained by an
on-the-chip 3-pF capacitor shown in Figure 18 on the following
page. No external compensation is required.

current gain of 03 ~ 1, 'its collector current is approximately equal
to Ir also. In operation this current flows through an external
feedback resistor which generates the output voltage signal. For
inverting applications, the non inverting input is often used to set
the de quiescent level at the output. Techniques for doing this are
discussed in the "NOrmal Design Procedure" section.

A noninverting input is obtained by adding a current mirror as
shown in Figure 17. Essentially all current which enters the noninverting input. I r • flows through the diode CRI. The voltage
drop across CRl corresponds to this input current magnitude and
this same voltage is applied to a matched device, 03. Thus 03 is
biased to conduct an emitter current equal to I r . -Since the alpha

Biasing Circuitry
The circuitry common to all four amplifiers is shown in Figure 19,
see next page. The purpose of this circuitry is to provide biasing
voltage for the PNP and NPN current sources used in the amplifiers.

06. Transistor Q7 reduces base current loading. The voltage
across resistor R2 is the sum of the voltage drops across CR2. CR3
and CR4. minus the VBE drops of transistor Q9 and diode CR5.
The current thus set is established by CR5 in ali the NPN current
sources (Q1 0, etc.). This technique results in current source magnitudes which are relatively independent of the supply voltage. Q11
(Figure 15) provides circuit protection from Signals that are negative
with respect to ground.

The voltage drops across diodes CR2. CR3 and CR4 are used as
references. The voltage across resistor R 1 is the sum of the drops
across CR4 and CR3 minus the VBE of Q8. The PNP current
sources IQ5. etc.1 are set to the magnitude VBE/RI by transistor

NORMAL DESIGN PROCEDURE
1. Output O-Point Biasing

C. Reference Voltage other than Vce Isee Figure 20)

A. A number of techniques may be devised to bias the quiescent

The biasing resistor Rr may be returned to a voltage (V r )
other than VCC. By setting Rf ; R r • Istill keeping Ir between 10 /lA and 200 /lA) the output de level will be equal
to V r . The expression for determining VOde is:

output voltage to an acceptable level. However, in terms of
loop gain considerations it is usually desirable to use the
non inverting input to effect the biasing as shown in Figures
3 and 4 (see the first page of this specification). The high
impedance of the collector of the non inverting "current
mirror" transistor helps to achieve the maximum loop gain
for any particular configuration. It is desirable that the noninverting input current be in the 10 IJA to 200 ~A range.

V

M

The noninverting input is normally returned to the Vee
voltage (which should be well filtered) through a resistor.
R r , allowing the input current, If. to be within the range of
10 /lA to 200 /lA. Choosing the feedback resislor. Rf. to be
equal to % R r will now bias the ampl ifier output de I evel to

V~C.

2. Gain Determination
A. Inverting Amplifier
The amplifier is normally used in the inverting mode. The
input may be eapacitively coupled to avoid upsetting the
dc bias and the output is normally capacitively coupled to
eliminate the dc voltage across the load. Note that when
the output is capacitively coupled to the load, the value of

This allows the maximum dynamic

range of the output voltage.

NORMAL DESIGN PROCEDURElcontinuedl
Isink becomes a limitation with respect to the load driving
capabilities of the device. The limitation is less severe if the
device is direct coupled. In this configuration, the ae gain
is determined by the ratio of Rf to Ri, in the same manner
as for a conventional operational amplifier;

B. Noninverting Amplifier
The MC3301 P may be used in the noninverting mode {see
Figure 4, first pagel. The amplifier gain in this configuration
is subject to the current mirror gain. In addition, the resistance of the input diode must be included in the value of

where 'r is input current in milliamperes. The noninverting
ac gain expression is given by:

The lower corner frequency is determined by the coupling
capacitors to the input and load resistors. The upper corner
frequency will usually be determined by the ampl ifier internal compensation. The amplifier unity gain bandwidth

is typically 4.0 MHz and with the gain roll-off at 20 dB per
decade, bandwidth will typically be 400 kHz with 20 dB of
closed loop gain or 40 kHz with 40 dB of closed loop gain.
The exception to this occurs at low gains where the input
resistor selected is large. The pole formed by the amplifier
input capacitance, stray capacitance and the input resistor
may occur before the closed loop gain intercepts the open
loop response curve. The inverting input capacity is typi-

The bandwidth of the noninverting configuration for a given
Rf value is essentially independent of the gain chosen. For
Rf = 510 kn the bandwidth will be in excess of 200 kHz
for noninverting gains of 1, 10, or 100. This is a result of
the loop gain remaining constant for these gains since the
input resistor is effectively isolated from the feedback loop.

OPERATION AND APPLICATIONS
Basic Ampl ifier
The basic amplifier is the common emitter stage shown in Figures
15 and 16. The active load '1 is buffered from the input transistor
by a PNP transistor, Q4, and from the output by an NPN transistor,
02. Q2 is biased class A by the current source '2. The magnitude
of '2 (specified 'sink) is a limiting factor in capacitively coupled

linear operation at the output. The sink current of the device can
be forced to exceed the specified level with an increase in the
distortion appearing at the output. Closed loop stability is maintained by an on-the-chip 3-pF capacitor shown in Figure 18. No
external compensation is required.

A noninverting input is obtained by adding a current mirror as

Neglecting error terms, the expression for determining VOdc

1. Output Q-Point Biasing
A. A number of techniques may be devised to bias the quiescent
output voltage to an acceptable level. However, in terms of
loop gain considerations it is usually desirable to use the
noninverting input to effect the biasing as shown in Figures
3 and 4. The high impedance of the collector of the noninverting "current mirror" transistor helps to achieve the
maximum loop gain for any. particular configuration. It is
desirable that the noninverting input current be in the 5 jJ.A

B. VCC Reference Voltage (see Figures 3 and 41

The error terms not" appearing in the above equation can
cause the dc operating point to vary up to 20% from the
expected value. Error terms are minimized by setting the
input current within the range of 5 J.1.A to 100 J.1.A.

The non inverting input is normally returned to the Vee
voltage (which should be well filtered) through a resistor,
R r , allowing the input current, Ir , to be within the range of
5 IJ.A to 100 IJ.A. Choosing the feedback .resistor, Rf, to be

3401P may be used in the noninverting mode (see Figure 4).
The amplifier gain in this configuration is subject to the
same error terms that affect the output

the gain may deviate as much as ±.20% from that expected.
In addition, the resistance of the input diode must be included in the value of the input resistor. This resistance is

The lower corner frequency is determined by the coupling

capacitors to the input and load resistors. The upper corner
frequency will usually be determined by the amplifier internal compensation. The amplifier unity gain bandwidth
is typically 5.0 MHz and with the gain roll·off at 20 dB per
decade, bandwidth will typically be 500 kHz with 20 dB of
closed loop gain or 50 kHz with 40 dB of closed loop gain.

The bandwidth of the noninverting configuration for a given
Rf value is essentially independent of the gain chosen. For
Rf = 510 kn the bandwidth will be in excess of 200 kHz
for noninverting gains of 1, 10, or 100. This is a result of
the loop gain remaining constant for these gains since the
input resistor is effectively isolated from the feedback loop.

The exception to this occurs at low gains where the input
resistor selected is large. The pole formed by the amplifier
input capacitance, stray capacitance and the input resistor
may occur before the closed loop gain intercepts the open
loop response curve. The inverting input capacity is typically 3.0 pF.

The MC3450 features four MC75107 type active pullup line
receivers with the addition of a common three-state strobe input.
When the strobe input is at a logic zero, each receiver output state is
determined by the differential voltage across its respective inputs.
With the strobe high, the receiver outputs are in the high impedance
state.
The MC3452 is the same as the MC3450 except that the outputs
are open collector which permits the implied "AND" function.
The strobe input on both devices is buffered to present a strobe
loading factor of only one for all four receivers and inverted to
provide best compatability with standard decoder devices.

TO ADDITIONAL
RECEIVERS

The MC3450/3452 can be used for single-ended as well as
differential line receiving. For single-ended line receiver applications, such as are encountered in minicomputers, the configuration shown in Figure 15 can be used. The voltage source,
which generates Vref, should be deSigned so that the Vref
voltage is halfway between VOH(min) and VOL(max). The
maximum input overdrive required to guarantee a given logic
state is extremely small, 25 mV maximum. This low-input overdrive enhances differential noise immunity. Also the high-input
impedance of the line receiver permits many receivers to be
placed on a single line with minimum load effects.

QUAD LINE DRIVER WITH
COMMON INHIBIT INPUT

MONOLITHIC MTTL COMPATIBLE
QUAD LINE DRIVER

MONOLITHIC SILICON
INTEGRATED CIRCUIT

The MC3453 features four MC75110 type line drivers with a
common inhibit input. When the inhibit input is high, a constant
output current is switched between each pair of output terminals in
response to the logic level at that channel's input. When the inhibit
is low, all channel outputs are nonconductive (transistors biased to
cut-off). This minimizes loading in party·line systems where a large
number of drivers share the same line.

The MC7700CP Series positive voltage regulators are identical to
the popular MC7800CP Series devices, except that they are specified
for only half the output current. Like the MC7800CP devices, the
MC7700CP three·terminal regulators are intended for local, on·card

Internal current limiting, thermal shutdown circuitry and safe·
area compensation for the internal pass transistor combine to make
these devices remarkably rugged under most operating conditions.

to the power supply filter with long wire lengths, or if the output
load capacitance is large. An input bypass capacitor should be
selected to provide good high-frequency characteristics to insure
stable operation under all lpad conditions. A 0.33 J.JF or larger
tantalum, mylar, or other capacitor having low internal impedance
at high frequencies should be chosen. If an aluminum electrolytic capacitor is U'Sed, its value should be 10 J.JF or larger. The
bypass capacitor should be mounted with the shortest possible
leads directly across the regulators input terminals. Normally good
construction techniques should be used to minimize ground loops
and lead resistance drops since the regulator has no external
sense lead.

The MC7800C Series of fixed voltage regulators are designed
with Thermal Overload Protection that shuts down the circuit
when subjected to an excessive power overload condition, Internal

Short-Circuit Protection that limits the maximum current the cir-

cuit will pass, and Output Transistor Safe-Area Compensation that
reduces the output short-circuit current as the voltage across the
pass transistor is increased.
In many low current applications, compensation capacitors are
not required.
However, it is recommended that the regulator
input be bypassed with a capacitor if the regulator is connected

The MC7800C series can be current boosted with a PNP transistor. The MJ2955 provides current to 5.0 amperes. Resistor R
in conjunction with the VSE of the PNP determines when the
pass transistor begins conducting; this circuit is not short-circuit
proof. Input-output differential voltage minimum is increased by
VSE of the pass transistor.

The circuit of Figure 12 can be modified to provide supply protec·
tion against short circuits by adding a short-circuit sense resistor,
Rsc/and an additional PNP transistor. The current sensing PNP
must be able to handle the short-circuit current of the threeterminal regulator. Therefore, a four-ampere plastic power tran·
sistor is specified.

MC7900C SERIES THREE-TERMINAL
NEGATIVE VOLTAGE REGULATORS

THREE-TERMINAL
NEGATIVE FIXED

The MC7900C Series of fixed output negative voltage regulators
are intended as complements to the popular MC7800C Series devices.
These negative regulators are available in the same seven·voltage
options as the MC7800C devices. In addition, two extra voltage
options commonly employed in MECL systems are also available
in the negative MC7900C Series.
Available in fixed output voltage options from -2.0 to -24 VOlts,
these regulators employ current limiting, thermal shutdown, and
safe·area compensation - mak ing them remarkably rugged under
most operating conditions. With adequate heat·sinking they can
deliver output currents in excess of 1.0 ampere.

When a boost transistor is used, short~ircuit currents are equal
to the sum of the series pass and regulator limits. which are
measured at 3.2 A and 1.8 A respectively in this case. Series pass
limiting is approximately equal to 0.6 V/RSC. Operation beyond
this point to the peak current capability of the MC7905C is pos-

sible if the regulator is mounted on a heat sink; otherwise thermal
shutdown will occur when the additional load current is picked up
by the regulator.

DUAL MEMORY DRIVER
The MC55325175325 is a monolithic integrated circuit memory
driver with logic inputs, and is designed for use with magnetic
memories.
The device contains two 600-mA source-switch pairs and two
600·mA sink-switch pairs. Source selection is determined by one of
two logic inputs, and source turn-on is determined by the source
strobe. Likewise, sink selection is determined by one of two logic
inputs, and sink turn-on is determined by the sink strobe. With this
arrangement selection of one of the four switches provides turn-on
with minimum time skew of the output current rise.

MONOLITHIC DUAL LINE DRIVERS
DUAL LINE DRIVERS

The MC75109 and MC7511 0 dual line drivers feature independent
channels with common voltage supply and ground terminals. Each
driver circuit provides a constant output current that switches to
either of two output terminals subject to the appropriate logic levels
at the input terminals. Output current can be switched "off"
(inhibited) by appropriate logic levels at the inhibit inputs. Output
current is nominally six milliamperes for the MC75109 and twelve
millamperes for the MC7511 O.
The inhibit feature permits use in party·line or data-bus applications. A strobe or inhibitor, common to both drivers, is included to
increase driver-logic versatility. With output current in the inhibited
mode,IO(off), is specified so that minimum line loading occurs when
the driver is used in a party·line system with other drivers. Output
impedance of the driver in inhibited mode is very high (the output
impedance of a transistor biased to cutoff).
All driver outputs have a common-mode voltage range of -3.0 volts
to +10 volts, allowing common·mode voltage on the line without
affecting driver performance.

DIFFERENTIAL PARTY-LINE OPERATION
Often in large computer systems it is desirable to attach
several drivers and receivers at different points along a
transmission line. Figure 16 shows an example of such a
Party-Line or Data Bus System. Only one driver may be
active at a time but all receivers may be active simultaneously. Such sharing or multiplexing of transmission
lines results in considerable savings and flexibility in systems interconnections. Isolation of inactive drivers from
the active driver is essential in party-I ine operation_ The
MC75113L guarantees this isolation even when power
supplies of some of the drivers in the system are "off"_
This important feature makes it unnecessary to simultaneously power-up all system components when the use

of only a few is required. As noted previously, all types of
differential driver systems have the advantage of differential noise cancellation not available with single-ended
driver systems. However, in multiple driver or party-line
systems the MC75113L, with "Push-Pull" outputs, has
the additional advantage of eliminating the uncancelled
common-mode noise spike which occurs during the
"enable" and "inhibit" cycles (required for party-line
operation in "Pull-Only" differential line drivers).
LINE TERMINATION
In any high-speed data transmission system proper
termination to prevent reflections is necessary_ Transmission line pairs in close proximity to ground such as

FIGURE 17A - CIRCUIT FOR zdm MEASUREMENT
Transmission L.ine Pair

microstrip, stripline, ribbon cable, and shielded twistedpair, exhibit two distinct characteristics impedances_ The
common-mode characteristic impedance (zcm) is due to
the two lines being at the same potential and carrying
equal currents in the same direction_ The differential-mode
characteristic impedance (Zdm) is due to the lines being at
equal but opposite potentials and carrying equal currents
in opposite directions_ Since both common-mode noise
and differential-mode data signals will be present on the
transmission lines, the lines must be terminated so that
both types of signals will be absorbed rather than reflected
at the termination points_ The differential-mode characteristic impedance of a particular line may be measured
from the circuit in Figure 17A_ The pulse transformer is
used to assure equal and opposite voltage and current
excursions on the pair of lines_ The value of zdm for each
line is equal to the value of the resistor needed to prevent
differential-mode reflections from appearing on the lines.
The circuit of Figure 17B may be used to measure the
value of common-mode characteristic impedance, Zcm. The

APPLICATIONS INFORMA nON (continued)
The value of R6 is equal to Zcm. The value of R2 may be
calculated from Equation 1. The value of R 1 and R3 may
be calculated from Equation 2 and 3 using the desired
value of offset voltage, VIO, and supply voltages, VCC
and VEE.

value of resistors which prevent common-mode reflections
is zcm. When measuring zcm and zdm for lines which are
part of a cable contain ing many lines, it is important to
terminate the remaining lines in approximately the same
way as they will eventually be terminated. This is because
the number of grounded conductors and terminated conductors in the cable will affect the value of zcm and zdm
measured.
Since 2 zcm
zdm, it is always possible to choose a
delta bridge of resistors which will correctly terminate
both the common-mode and differential-mode signals. The
common-mode signal is correctly terminated by a resistor
of value zcm to ground from each line. The differentialmode signal is correctly terminated by a resistor whose
value may be calculated from Equation 1.

The resistor values R4 and R5 are chosen so that the
parallel combinations of R 1 and R4 and also R3 with R5

Additional information regarding common-mode and differential-mode characteristic impedance may be found in
References 1 and 2. (In the References zcm = zoe, the

The choice of offset voltage, VIO, depends upon the differential mode characteristic impedance. Since the minimum total differential signal produced by the MC75113L
onto a properly terminated transmission path is:

USE WITH POPULAR DIFFERENTIAL RECEIVERS
The differential·output signal of the MC75113L is zero
when the output is "off". However, popular differential
line receivers such as the MC75107, which have thresholds
of approximately ±25 mV, require a positive differential
signal to turn "on" and a negative differential signal to
turn "off." Therefore, when using the MC75113L (which
has no negative output signal) with th is type of line receiver the line must be offset in voltage to provide the
required negative differential signal. This is easily accomplished using the termination scheme shown in
Figure 18.

both sides of the receiver's zero volt threshold should be:

EXAMPLE OF CALCULATION OF TERMINATION
RESISTOR VALUES
Suppose the MC75113L is to be used with VCC = +5.0
volts and VEE = -6.0 volts to drive a transmission line
with zcm = 85 .12 and zdm = 112 n. The offset vo Itage
required for equal noise margin on both sides of the
receiver'szero·volt threshold isfound by Equation 7 to be:
VIO = 4.5 mA x (112) = 0.504 volts

(8)

From Figure 17 it may be seen that R6 = zcm = 85.12.
R2 is found from Equation 1:
R2

2 (112) (85) = 328.12
2 (85) -112

(9)

R 1 and R3 are found from Equations 2 and 3 to be:
R 1 = ~ x _5_ - 556 .12
2
0.504

(10)

R3=-112 -6.0 V =667.12
2 x 0.504

(11)

R3 and R5 are found from Equation 4 and 5:
R4 = 85 (556) = 100.12
556-85

(12)

R5 = 85 (667)= 97 .12
667-85

(13)

The resulting structure is shown in Figure 19.

DUAL LINE RECEIVER

_ _ _ _ _ _ _-----'

MONOLITHIC DUAL LINE RECEIVER
The MC75140Pl is a dual line receiver with common Strobe and
Reference inputs. The Reference voltage is externally applied. This
voltage may range from 1.5 to 3.5 volts, thus allowing for adjustment of maximum noise immunity in a given system design. The
MC75140Pl is intended for use as a single-ended receiver in MTTL
systems. Use in a party-line (bus-organized) system is aided by the
low input current of the receiver.

PACKAGING AND HANDLING
The MCBC1109 beam-lead 58aled-junction linear integrated circuit is available ,in chip form (non-encapsulated)
as shown in the outline dimensional drawing. The shipping
carrier for chips is a 2" square glass plate on which the
chips .re placed. A thin layer of polymer film covers the
plate and retains the chips in place. The chips do not adhere
to the film when it Is lifted to remove them from the
carrier. Care must be exercised when removing the chips
from the carrier to ensure that the beams are not bent.
A vacuum pickup is useful for this ouroose.

The MCBCI723/MCBI723F is a positive or negative voltage
regulator designed to deliver load current to 150 mAdc. Output
current capability can be increased to several amperes through use of
one or more external pass transistors. Beam-lead products employ a
silicon-nitride dielectric that hermetically seals the chip, eliminating
the need for a hermetic package. The beam leads are gold cantilevered structures extending from the chip. These beams bond readily
to a gold metalized substrate providing one of the most reliable
interconnection systems known for semiconductor devices.

PACKAGING AND HANDLING

MCC1558/MCC1458 BONDING DIAGRAM

The MCC1558/MCC1458 dual operational amplifiers are now
available as a single monolithic die or encapsulated in a variety of

hermetic and plastic packages. The phosphorsilicate passivation
protects the metalization and active area of the die but care must
be exercised when removing the dice from the shipping carrier to
avoid scratching the bonding pads. A vacuum pickup is useful for
the handling of dice. Tweezers are not recommended for this

purpose.
The non-spill type shipping carrier consists of a compart~
mentalized tray and fitted cover. Die are placed in the carrier
with geometry side up.

All dimensions are nominal and
in mils (10-3 inches).

Note:
The record/playback characteristics shown in Figures 8 and 9
were taken with the preamplifier driven by a 50 ohm source. The
curves are typical of a desired response for the preamplifier; however, every type of tape recording and playback head is different
and this circuit will not necessarily satisfy all requirements. No particular tape head was used as a basis for circuit design. The circuit
is only an example showing the equalization network configuration.
The ideal preamplifier will have an input impedance approx·
imately 10 times the highest impedance of the tape head and every
preamplifier circuit must be designed uSi.ng a test tape to verify
the response of the design.

APPLICATIONS INFORMATION

chosen to ensure that current limiting occurs before the collector
voltage drops to a value low enough to forward bias the collectorbase junction. In a transformer coupled circuit, the maximum
allowable load can be derived from

Because of the low reverse transfer admittance of the MFC6010.
stability will be dependent mainly upon circuit layout.

With

careful design, very high gain (in the order of 40 dB) may be

achieved at 10.7 MHz. The bias and supply currents may be varied
from their normal values (shown in Figure 4) by shunting addi~
tional resistance from pin 6 to ground or to the supply line.

Although less gain may be realized when using the MFC6010
as a limiter, it is recommended that it be operated in a non-saturated

'0

mode. This mode of operation results in a high output impedance
at limiting. Therefore the operation of the demodulator circuit is
not subject to variable loading of the limiter output.
In order to avoid driving the amplifier transistor components
of the MFC6010 into saturation, the load resistance must be

where values for
may be determined from Figure 4 (providing
the bias currents have not been altered from their normal values).
I n order to avoid degradation of AM rejection, the input signal
should not exceed one volt (rms).

THERMAL CHARACTERISTICS
Characteristic
Thermal Resistance, Junction to Ambient
*Thermal resistance is measured in still air with fine wires connected to the leads, representing

the "worst case" situation.
For a larger power requirement, pin 1 must be soldered to at least one sq. in. of copper

e

foil on the printed circuit board. The JA will be no greater than +90 0 C/W. Thus, 1.39
Watts could be dissipated at +25 0 C, which must be linearty derated at 11.1 mW/oC from
+25 0 C to +150 0 C.

Ratio

Note 1. For supply voltages less than ±. 15 volts, the absolute
maximum input voltage is equal to the slJpply voltage.
Nota 2. A continuous short-circuit duration capability is specified
for M LM 11 OG and M LM21 OG as follOWS:

case tempe,a-

tures upto +1250 Cand ambient temperatures up to +70o C;
for the MLM310G up to +70o C case temperature and
+5SoC ambient temperature apply. A resistor "(greater than
2.0 kilohms) must be inserted in series with the input when
the amplifier is driven from a low impedance source, thus
preventing damage when the output is shorted.

Note 3. The maximum junction temperature of the MLM110 is
+150o C. for the MLM210G - + 100°C, and for the
M LM31 OG - +85 0 c. For operating at elevated temperatures, the package must be derated based on a thermal
resistance of 1500 C/W - junction to ambient, or 45°C junction t'O case.
Note 4. All listed specifications apply for ±. 5.0 V ~ VS:S:; ±.18 V
and T A::::; +2So c unless otherwise noted.
Note 5. Increased output swing under load'can be obtained by
connecting an external resistor between the booster and
VEE terminals (pins 4 and 51.

HIGH PERFORMANCE
VOLTAGE COMPARATORS

HIGHLY FLEXIBLE VOLTAGE COMPARATORS
The ability to operate from a single power supply of 5.0 to 30
volts Dr ± 15·volt split supplies, as commonly used with operational
amplifiers, makes the MLM111/MLM211/MLM311 a truly versatile
comparator. Moreover, the inputs of the device can be isolated from
system ground while the output can drive loads referenced either to
ground, the Vee Dr the VEE supply. This flexibility makes it
possible to drive MDTL, MRTL, MTTL, or MOSlogic. The output
can also switch voltages to 50 volts at currents to 50 mAo Thus the
MLM111/MLM211/MLM311 can be used to drive relays, lamps Dr
solenoids.

This rating applies for ±15-volt supplies. The positive input voltage limit is 30 volts above the negative supply. The negative input
voltage limit is equal to the negative supply voltage or 30 volts below the positive supply, whichever is less.

The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply
with a 1.0-mA load. Thus, these parameters define an error band and take into account the "worst case" effects of voltage gain and
input impedance.

The response time specified is for a 100-mV input step with 5.0-mV overdrive.

APPLICATIONS INFORMATION
OPERATION OF THE MMH0026
The simplified schematic diagram of MMH0026, shown
in Figure 17, is useful in explaining the operation of the
device. Figure 17 illustrates that as the input voltage level
goes high, diode 01 provides an 0.7·volt "dead zone"
thus ensuring that 02 is turned "on" and 04 is turned
"off" before 07 is turned "on". This prevents undesirable
"current spiking" from the power supply, which would
occur if 07 and 04 were allowed to be "on" simul·
taneously for an instant of time. Diode 02 prevents
"zenering" of 04 and provides an initial discharge path
for the output capacitive load by way of 02.

The complete circuit, Figure 1, basically creates Dar·
lington devices of transistors 07, 04 and 02 in the
simplified circuit of Figure 17. Note in Figure.1 that
when the input goes negative with respect to V EE, diodes
07 through 010 turn "on" assuring faster turn "off" of
transi$tors 01, 02, 06 and 07. Resistor R6 insures that
the output will charge to within one VBE voltage drop
of the Vee supply.

As the input voltage level goes low, the stored charge in
02 is used advantageously to keep 02 "on" and 04 "off"
until 07 is "off". Again undesirable "current spiking" is
prevented. Due to the external capacitor, the input side
of Cin goes negative with respect to VEE causing 09 to
conduct momentarily thus assuring rapid turn "off"
of 07.

SYSTEM CONSIDERATIONS
Overshoot:
In most system applications the output waveform of the
MMH0026 will "overshoot" to some degree. However,
"overshoot" can be eliminated or reduced by placing a
damping resistor in series with the output. The amount
of resistance required is given by: RS = 2.j L/CL where
L is the inductance of the line and eL is the load capac'
itance. In most cases a series of damping resistor in the
range of 1().to-50 ohms will be sufficient. The damping
resistor also affects the transition times of the outputs.
The speed reduction is given by the formula:
tTHL '" tTLH = 2.2 RS CL (RS is the damping resistor).
Crosstalk:
The MMH0026 is sensitive to crosstalk when the output
voltage level is high (VO '" Vee). With the output in· the
high voltage level state, 03 and 04 are essentially turned
"off". Therefore, negative'going crosstalk will pull the
output down until 04 turns "on" sufficiently to pull the
output back towards Vce. This problem can be min·
imized by placing a "bleeding" resistor from the output
to ground. The "bleeding" resistor should be of suf·
ficient size so that 04 conducts only a few milliamperes.
Thus, when noise is coupled, 04 is already "on" and the
line is quickly clamped by 04. Also note that in Figure 1
06 clamps the output one diode·voltage drop above Vec
for positive·going crosstalk.

Power Supply oecoupling:
The decoupling of Vee and VEE is essential in most
systems. Sufficient capacitive decoupling is required to
supply the peak surge currents during switching. At least
a O.l·j.lF to 1.().j.lF low inductive capacitor should be
placed as close to each driver package as the layout will
permit.

Input Driving:
For those applications requIring split power supplies
(VEE < GNo), ac coupling, as illustrated in Figure 3,
should be employed. Selection of the input capacitor
size is determined by the desired output pulse width.
Maximum performance is attained when the voltage at

MMH0026, MMH0026C (continued)

APPLICATIONS INFORMATION (continued)

the input of the MMH0026 discharges to just above the
device's threshold voltage (about 1.5 V). Figure 7 shows
optimum values for Cin versus the desired output pulse
width. The value for Cin may be roughly predicted by:
Cin = (2 x 10- 3 ) (PWo).
(1)
For an output pulse width of 500 ns, the optimum value
for Cin is:
Cin = (2 x 10- 3 ) (500 x 10- 9 ) = 1000 pF.
If single supply operation is required (VEE = GNO), then
dc coupling as illustrated in Figure 4 can be employed.
For maximum switching performance, a speed·up capac·
itor should be employed with dc coupling. Figures 13
and 14 show typical switching characteristics for various
values of input resistance and capacitance.

POWER CONSIOERATIONS
Circuit performance and long·term circuit reliability are
affected by die temperature. Normally, both are improved
by keeping the integrated circuit junction temperatures
low. Electrical power dissipated in the integrated circu it
is the source of heat. This heat source increases the
temperature of the die relative to some reference point,
normally the ambient temperature. The temperature in·
crease depends on the amount of power dissipated in the
circuit and on the net thermal resistance between the
heat source and the reference point. The basic formula
for converting power dissipation into junction temper·
ature is:

With these maximum junction temperature values, the
maximum permissible power dissipation at a given
ambient temperature may be determined. This can be
done with equations (2) or (3) and the maximum thermal
resistance values given in Table 1 or alternately, by using
the curves plotted in Figure 18. If, however, the power
dissipation determined by a given system produces a
calculated junction temperature in excess of the recom·
mended maximum rating for a given package type, something must be done to reduce the junction temperature.

Power Dissipation for the MMH0026 MOS Clock Driver:
The power dissipation of the device (PO) is dependent
on the following system requirements: frequency of op·
eration, capacitive loading, output voltage swing, and
duty cycle. This power dissipation, when substituted into
equation (3), should not yield a junction temperature,
TJ, greater than TJ(max) at the maximum encountered
ambient temperature. T J(max) is specified for three
integrated circuit packages in the maximum ratings
section of this data sheet.

There are two methods of lowering the junction tem·
perature without changing the system requirements.
First, the ambient temperature may be reduced sufficiently to bring TJ to an acceptable value. Secondly,
the8CA term can be reduced. L,oweringthe 8CA term can
be accomplished by increasing the surface area of the
package with the addition of a heat sink or by blowing
air across the package to promote improved heat
dissipation.

(continued)

APPLICATIONS INFORMATION (continued)

The following examples illustrate the thermal considerations necessary to increase the power capability of the
MMH0026.

using the previous formulas and constants, a new safe
operating area can be generated for any output voltage
swing and duty cycle desired.

Assume that the ceramic package is to be used at a
maximum ambient temperature (TA) of +70 0 C. From
Table 1: IIJA(max) ~ 1500 C/watt, and from the maximum rating section of the data sheet: T J(max) ~ +175 0 C.
Substituting the above values into equation (3) yields a
maximum allowable power dissipation of 0.7 watts. Note
that this same value may be read from Figure 18. Also
note that this power dissipation value is for the device
mounted in a socket.

Note from Figure 19, that with highly capacitive loads,
the maximum switching frequency is very low. The
switching frequency can be increased by varying the
following factors:
(a) decrease T A
(b) decrease the duty cycle
(c) lower package thermal resistance II JA.
In most cases conditions (a) and (b) are fixed due to
system requirements. This leaves only the thermal resistance II JA that can be varied.

Next, the maximum power consumed for a given system
application must be determined. The power dissipation
of the MaS clock driver is conveniently divided into
dc and ac components. The dc power dissipation is
given by:
Pdc

~

(VCC - VEE) x (lccU x (Duty Cycle)

Note from equation (2) that the thermal resistance is
comprised of two parts. One is the junction-to-case
thermal resistance (II JC) and the other is the case-toambient thermal resistance (IICA). Since the factor Ii JC
is a function of the die size and type of bonding employed,
it cannot be varied. However, the IICA term can be
changed as previously discussed, see Page 7.

Note that Figure 15 is a plot of equation (4) for three
values of (VCC-VEE). For this example, suppose that
the MOS clock driver is to be operated with V CC ~ + 16 V
and VEE ~ GND and with a 50% duty cycle. From
equation (4) or Figure 15, the dc power dissipation (per
driver) may be found to be 256 mW. If both drivers
withtn the package are used in an identical way, the total
dc power is 512 mW. Since the maximum total allowable
power dissipation is 700 mW, the maximum ac power
that can be dissipated for this example becomes:

Figure 16 gives the maximum ac power dissipation versus
switching frequency for various capacitive loads with
VCC ~ 16 V and VEE ~ GND. Under the above conditions, and with the aid of Figure 16, the safe operating
area beneath Curve A of Figure 19 can be generated.

Heat Sink Considerations:
Heat sinks come in a wide variety of sizes and shapes that
will accomodate almost any IC package made. Some of
these heat sinks are illustrated in Figure 20. In the
previous example, with the ceramic package, no heat sink
and in a still air environment, liJA(max) was 1500 CIW.

Since both drivers have a maximum ac power dissipation of 188 mW, the maximum ac power per driver
becomes 94 mW. A horizontal line intersecting all the
capacitance load lines at the 94 mW level of Figure 16
will yield the maximum frequency of operation for each
of the capacitive loads at the specified power level. By

For the following example the Thermalloy 6012Btype
heat sink, or equivalent, is chosen. With this heat sink, the
IICA for natural convection from Figure 21 is 44 0 C/W.
From Table 1 liJc(max) ~ 500 CIW for the ceramic

package. Therefore, the new 0JA(max) with the 60128
heat sink added becomes:
0JA(max) = 50 0C/W + 44 0 CIW = 94 0 C/W.

As illustrated in Figure 22, forced air can be employed to
reduce the JA term. Note, however, that this curve is
expressed in terms of typical JA rather than maximum
0JA. Maximum 0JA can be determined in the following

°

Thus the addition of the heat sink has reduced JA(max"l
from 1500 C/W down to 94 0 CIW. With the heat sink, the
maximum power dissipation by equation (3) at T A =

Since:

This gives approximately a 58% increase in maximum
power dissipation. The safe operating area under Curve C
of Figure 19 can now be generated as before with the aid
of Figure 16 and equation (5).

Then:
(7)

Therefore, in still air
0CA(tyP) = 1000 CIW - 27 0 CIW = 7JOC/W

Thus 0CA(tyP) has changed from 73 0 CIW (still air) to

As with the previous examples, the dc power at 50% duty
cycle is subtracted from the maximum allowable device
dissipation (PD) to obtain a maximum Pac. The safe
operating area under Curve D of Figure 19 can now be
generated from Figure 16 and equation (5).
Heat Sink and Forced Air Combined:
Some heat sink manufacturers provide data and curves of
IJCA for still air and forced air such as illustrated in
Figure 23. For example the 60128 heat sink has an
IJCA = 17 oC/W at 500 LFPM as noted in Figure 23.
From equation (6):
Max IJJA = 500 C/W + 17 oC/W = 67 0 C/W
From equation (3) at T A = +700 C

With maximum (}JA known, the maximum power dissipation can be found and the safe operating area determined as before. See Curve 8 in Figure 19.

Note from Table 1 and Figure 22 that if the 14-pin
ceramic package is mounted directly to the PC board
(2 oz. cu. underneath), that typicallJJA is considerably
less than for socket mount with still air and no heat sink.
The following procedure can be employed to determine a
safe operating area for this condition.
Given data from Table 1:
typical () JA = 1000 C/w
typical () JC = 27 0 C/W
From Curve 2 of Figure 22,IJJA(tyP) is 75 0 C/W for a
PC mount and no air flow. Then the typical IJCA is
75 0 C/W - 27 0 C/W = 48 0 C/W_ From Table 1 the typical
value of IJCA for socket mount is 1000 C/w - 27 0 C/W =
73 oC/W. This shows that the PC board mount results in
a decrease in typicallJCA by a ratio of 1 :1.5 below the
typical value of (}CA in a socket mount. Therefore, the
maximum value of socket mount ()CA of 100 0 C/W
should also decrease by a ratio of 1: 1.5 when the device
is mounted in a PC board. The maximum (}CA becomes:
1000 C/W
IJCA = - - - = 66 0 C/W for PC board mount
1.5
Therefore the maximum () JA for a PC mount is from
equation (6).
IJ JA = 50 0 C/W + 66 0 e/W = 1160 C/W.

CONCLUSION
In most cases, heat sink manufacturer's publish only
IJCA socket mount data. Although IJCA data for PC
mounting is generally not available, this should present
no problem. Note in Figure 22 that an air flow greater
than 250 LFPM yields a socket mount IJ JA approximately
6% greater than for a PC mount. Therefore, the socket
mount data can be used for a PC mount with a· slightly
greater safety factor. Also it should be noted that thermal
resistance measurements can vary widely. These measurement variations are due to the dependency of IJ CA on the
type environment and measurement techniques employed_ For example, IJCA would be greater for an
integrated circuit mounted on a PC board with little or
no ground plane versus one with a substantial ground
plane. Therefore, if the maximum calculated junction
temperature is on the border line of being too high for a
given system application, then thermal resistance measurements should be done on the system to be absolutely
certain that the maximum junction temperature is not
exceeded.
