INTRODUCTION
The rapid advance in high-tech digital processing creates new demands for microprocessor-compatible circuits
that can sense, amplify, and convert analog signals or provide regulated power to a system. In this volume,
Texas Instruments presents specifications and technical information on our broad line of integrated circuits
designed for applications that involve analog Signal conditioning. That product line includes:
Operational amplifiers
Voltage comparators
Regulators
Power supply monitors
Switching-mode power supply circuits
Hall-effect circuits
Current mirrors
Floppy-disk circuits for control, reading, or writing
Timers
AID converters
Video amplifiers
Analog switches
These circuits span the recent rapid development of integrated circuit technology from classical bipolar through
BIFET'" and BIDFET'" to TI's new LinCMOS" processing that provides a step-function improvement in input
impedance, power dissipation, and threshold stability. New surface-mount packages include both plastic and
ceramic chip carriers and the small-outline packages that increase board density with little impact on power
handling capability.
Ordering information and mechanical data are in the Appendix. Section 1 contains an alphanumeric index that
lists page numbers for all the device types included, and each data sheet section provides a functional selection
guide to the devices in that section.
While this volume offers design and specification data only for Linear components, complete technical data
for any TI semiconductor product is available from:

description
The LM101A, LM201A, and LM301A are highperformance operational amplifiers featuring very low
input bias current and input offset voltage and current
to improve the accuracy of high-impedance circuits
using these devices. The high common-mode input
voltage range and the absence of latch-up make these
amplifiers ideal for voltage-follower applications. The
devices are protected to withstand short-circuits at
the output. The external compensation of these
amplifiers allows the changing of the frequency
response (when the closed-loop gain is greater than
unity) for applications requiring wider bandwidth or
higher slew rate. A potentiometer may be connected
between the offset-null inputs (N 1 and N2), as shown
in Figure 7, to null out the offset voltage.
The LM1 01 A is characterized for operation OVer the
full military temperature range of - 55°C to 125°C,
the LM201 A is characterized for operation from
- 25°C to 85 °C, and the LM301 A is characterized
for operation from ooC to 70°C.

description
The LM110 series are monolithic operational
amplifiers internally connected as unity-gain noninverting amplifiers. They use transistors in the
input stage to get low bias current without
sacrificing speed and they have internal
frequency compensation and provision for offset
balancing. Increased output swing under load
can be obtained by connecting an external
resistor between the Booster terminal and the
VCC - terminal.

These devices consist of two independent. high-gain,
frequency-compensated operational amplifiers that
were designed specifically to operate from a single
supply over a wide range of voltages. Operation from
split supplies is also possible so long as the difference
between the two supplies is 3 volts to 30 volts (3 volts
to 26 volts for the LM2904), and the VCC pin is at
least 1 .5 volts more positive than the input commonmode voltage. The low supply current drain is
independent of the magnitude of the supply voltage.
Applications include transducer amplifiers, doc
amplification blocks, and all the conventional
operational amplifier circuits that now can be more
easily implemented in single-supply-voltage systems.
For example, these devices can be operated directly
off of the standard five-volt supply that is used in
digital systems and will easily provide the required
interface electronics without requiring additional
± 15-volt supplies.

description

BAL/COMP 1

The LM218 and LM318 are precision, high-speed
operational amplifiers designed for applications
requiring wide bandwidth and high slew rate. They
feature a factor-of-ten increase in speed over general
purpose devices without sacrificing de performance.

These operational amplifiers have internal unity-gain
>--OUTPUT
frequency compensation. This considerably simplifies
INVERTING (2)
their application since no external components are
INPUT INnecessary for operation. However, unlike most
internally compensated amplifiers, external frequency compensation may be added for optimum performance, For
inverting applications, feed-forward compensation will boost the slew rate to over 150 V/p.s and almost double the
bandwidth. Overcompensation may be used with the amplifier for greater stability when maximum bandwidth is not
needed. Further, a single capacitor may be added to reduce the settling time for 0.1 % error band to under 1 p.s.
The high speed and fast settling time of these operational amplifiers make them useful in A/D converters, oscillators,
active filters, sample and hold circuits, and general purpose amplifiers.
The LM218 is characterized for operation from - 25°C to 85 °C, and the LM318 is characterized for operation from

NOTES: 1. All voltage "alues, unless otherwise noted, are with respect to the midpoint between VCC+ and VCC-'
2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.
3. The inputs are shunted with two opposite·facing base·emitter diodes for over voltage protection. Therefore, excessive current will flow if a differential
input voltage in excess of approximately 1 V is applied between the inputs unless some limiting resistance is used.
4. The output may be shorted to ground or either power supply. For the LM218 only, the unlimited duration of the short·circuit applies at (or below)
85°C case temperature or 75 °C free-air temperature.
5. For operation above 25°C free-air temperature, refer to Dissipation Derating Curves, Section 2. In the JG package, LM218 and LM318 chips
are glass-mounted.

that were designed specifically to operate from a
single supply over a wide range of voltages. Operation
from split supplies is also possible. The low supply

Clamp transistors are included that prevent the Input voltages from swinging below ground more than approximately - 0.3 volt. The negative input
currents that may result from large signal overdrive with capacitive input coupling must be limited externally to values of approximately -1 rnA.
Negative input currents in excess of -4 mA will cause the output voltage to drop to a low voltage. These values apply for anyone of the Input
terminals. If more than one of the input terminals are aimultaneously driven negative. maximum currents are reduced. Common-mode current biasing
can be used to prevent negative input voltages.

TYPES LM2900, LM3900
QUADRUPLE OPERATIONAL AMPLIFIERS
TYPICAL APPLICATION DATA
Norton (or current-differencing) amplifiers can be used in most standard general-purpose op-amp applications.
Performance as a dc amplifier in a single-power-supplymode is not as precise as a standard integrated-circuit operational
amplifier operating from dual supplies. Operation of the amplifier can best be understood by noting that input currents
are differenced at the inverting input terminal and this current then flows through the external feedback resistor to
produce the output voltage. Common-mode current biasing is generally useful to allow operating with signal levels
near (or even below) ground.
Internal transistors clamp negative input voltages at pproximately - 0.3 volt but the magnitude of current flow has
to be limited by the external input network. For operation at high temperature, this limit should be approximately
-100 microamperes.

•

Noise immunity of a Norton amplifier is less than that of standard bipolar amplifiers. Circuit layout is more critical
since coupling from the output to the non inverting input can cause oscillations. Care must also be exercised when
driving either input from a low-impedance source. A limiting resistor should be placed in series with the input lead
to limit the peak input current. Current up to 20 milliamperes will not damage the device but the current mirror on
the noninverting input will saturate and cause a loss of mirror gain at higher current levels, especially at high operating
temperatures.

description
The NE5532 and NE5532A are monolithic high-performance operational amplifiers combining excellent dc and ac
characteristics. They feature very low noise. high output drive capability, high unity-gain and maximum-output-swing
bandwidths, low distortion, high slew rate, input-protection diodes, and output short-circuit protection. These operational
amplifiers are internally compensated for unity gain operation. The NE5532A has guaranteed maximum limits for
equivalent input noise voltage.
The NE5532 and NE5532A are characterized for operation from OoC to 70°C.

description

~

These devices represent a breakthrough in operational amplifier performance, Low offset and long-term stability are
achieved by means of a low-noise, chopperless, bipolar-in put-transistor amplifier circuit. For most applications, no
external components are required for offset nulling and frequency compensation, The true differential input, with a
wide input voltage range and outstanding common-mode rejection, provides maximum flexibility and performance
in high-noise environments and in non inverting applications. Low bias currents and extremely high input impedances
are maintained over the entire temperature range. The OP-07 is unsurpassed for low-noise, high-accuracy amplification
of very-)ow-Ievel signals.

description
The OP·12 devices are precision low-input·
current internally compensated operational
amplifiers. The devices are improved versions of
the LM 1OS series. The OP·12 amplifiers exhibit
low input bias current and input offset voltage
and current to improve the accuracy of high·
impedance circuits using these devices. The
devices feature short·circuit protection and
internal frequency compensation.

NOTES: 1. All voltage values. except otherwise noted, Bf8 with respect to the midpoint between VCC+ and VCC-'
2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.
3. The inputs are shunted with back-to-back diodes for input overvoltage protection. Therefore, excessive current will flow if 8 differential voltage
in excess of 1 volt is applied between the inputs unless some limiting resistance is provided •
4. The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating
'
is not exceeded.
5. For operation above 25°C free-air temperature. refer to Dissipation Derating Curves. Section 2.ln the JG packages, OP-12A, OP-12B, and OP-12C
chips are allov-mounted; OP-12E. OP-12F. and OP-12G chips are glass-mounted.

NOTES: 1. All voltage values. except differential input voltage, are with respect to the midpoint between VCC+ and VCC-'
2. Because of the back-ta-back diodes protecting the differential inputs, input current can become excessive if differential input voltage reaches

approximately 0.7 volts.
3. For operation above 25°C free-air temperature, refer to Dissipation Derating Curves, Section 2. In the J package, OP-227 chips are glass mounted.

description
The RC4559 is a dual high-performance operational amplifier. The high common-mode input voltage and
the absence of latch-up make this amplifier ideal for low-noise signal applications such as audio preamplifiers
and signal conditioners. This amplifier features a guaranteed dynamic performance and output drive
capability that far exceeds that of the general-purpose type amplifiers.

description
The SE5534, SE5534A, NE5534, and NE5534A are monolithic high-performance operational amplifiers combining
excellent dc and ac characteristics. Some of the features include very low noise; high output drive capability, high
unity·gain and maximum-output-swing bandwidths, low distortion, and high slew rate.
These operational amplifiers are internally compensated for a gain equal to or greater than three. Optimization of the
frequency response for various applications can be obtained by use of an external compensation capacitor between
COMP and COMP/BAL The devices feature input-protection diodes, output short-circuit protection, and offset-voltage
nulling capability.
The SE5534A and NE5534A have guaranteed maximums on equivalent input noise voltage.
The SE5534 and SE5534A are characterized for operation over the full military temperature range of - 55°C to 125°C;
the NE5534 and NE5534A are characterized for operation from ooC to 70°C.

NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between
+ and
2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage.
3. Excessive current will flow if a differential input voltage in excess of approximately 0.6 V is applied between the inputs unless some limiting
resistance Is used.
4. The output may be shorted to ground or either power suppiy. Temperature and/or supply voltages must be limited to ensure the maximum dissipation
rating is not exceeded.
5. For operation above 25 °C free~air temperature, refer to the Dissipation Derating Curves, Section 2. In the JG package, SE5534 and SE5534A
chips .are alloy~mounted; NE5534 and NE5534A chips are glass~mounted.
6. For FH and FK packages, power rating and derating factor will vary with actual mounting technique used. The values stated here are believed

to be conservative.

The TL022 is a dual low-power operational amplifier
designed to replace higher power devices in many
applications without sacrificing system performance,
High input impedance, low supply currents, and low
equivalent input noise voltage over a wide range of
operating supply voltages result in an extremely,
versatile operational amplifier for use in a variety of
analog applications including battery-operated circuits,
Internal frequency compensation, absence of latchup, high slew rate, and output short-circuit protection
assure ease of use,

NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between VCC+ and VCC-2. Differential voltages are at the noninverting input terminal with respect to the inverting input terminal.
3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 1 5 volts, whichever is less.
4. The output may be shorted to ground or to either supply. Temperature and/or supply voltages ":lust be limited to ensure that the dissipation rating
is not exceeded.
5. For operation above 25°C free..air temperature. refer to Dissipation Derating Curves in Section 2. In the JG package, the TL06SI, Tl066C. Tl066AC,

description
The JFET-input operational amplifiers on the TL07 _ series are designed as low-noise versions of the TL08_ series
amplifiers with low input bias and offset currents and fast slew rate. The low harmonic distortion and low noise make
the TL07 _ series ideally suited as amplifiers for high-fidelity and audio preamplifier applications. Each amplifier features
JFET-inputs (for high input impedance) coupled with bipolar output stages all integrated on a single monolithic chip.
Device types with an "M" suffix are characterized for operation over the full military temperature range of - 55°C
to 125°C. those with an "1" suffix are characterized for operation from - 25°C to 85 °C. and those with a "c" suffix
are characterized for operation from 0 °C to 70°C.

All voltage values, except differential vott~ges. are with respect to the midpoint between Vee + and VCC-'
Differential voltages are at the noninverting input terminal with respect to the inverting input terminal.
The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.
The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating

is not exceeded.
5. For operation above 25°C free-air temperature, refer to Dissipation Derating Curves, Section 2. In the J and JG packages. TL07 _M chips are
alloy-mounted; TL07 _I. TL07 _C, TL07 _AC. and TL07 _Be chips are glass mounted.

JFET-INPUT OPERATIONAL AMPLIFIERS
description
The TL08_ JFET-input operational amplifier family is designed to offer a wider selection than any previously developed
operational amplifier family. Each of these JFET-input operational amplifiers incorporates well-matched, high-voltage
JFET and bipolar transistors in a monolithic integrated circuit. The devices feature high slew rates, low input bias
and offset currents, and low offset voltage temperature coefficient. Offset adjustment and external compensation
options are available within the TL08_ family.
Device types with an "M" suffix are characterized for operation over the full military temperature range of - 55°C
to 125°C, those with an "I" suffix are characterized for operation from - 25°C to 85 °C, and those with a "C" suffix
are characterized for operation from 0 °C to 70°C.

description
These JFET-input operational amplifiers incorporate well-matched high-voltage JFET and bipolar transistors in a
monolithic integrated circuit. They feature low input offset voltage, high slew rate, low input bias and offset current,
and low temperature coefficient of input offset voltage. Offset-voltage adjustment is provided for the TL087 and TL088.
Device types with an "M" suffix are characterized for operation over the full military temperature range of - 55°C
to 125°C, those with an "I" suffix are characterized for operation from - 25°C to 85 °C, and those with a "c" suffix
are characterized for operation from 0 °C to 70°C.

TL294

These devices are high-speed operational amplifiers
designed for applications requiring wide bandwidth
and a fast slew rate. These monolithic circuits
incorporate new high-frequency P-N-P transistors that
eliminate the need for large feed-forward capacitors
required in previous moderately high-frequency
designs to pass the signal around slow lateral P-N-P
stages.
These operational amplifiers have a typical full-power
bandwidth of 400 kilohertz for a 20-volt peak-to-peak
output swing. because of the higher 20-megahertz
unity-gain bandwidth, the typical open-loop gain at the
400-kilohertz full-power bandwidth is a very
respectable 34 decibels.

The TLC251 and TLC271 series are low-cost, lowpower programmable operational amplifiers designed
to operate with single or dual supplies. Unlike
traditional metal-gate CMOS op amps, these devices
utilize Texas Instruments silicon-gate LinCMOSTM
process, giving them stable input offset voltages
without sacrificing the advantages of metal-gate
CMOS. This series of parts is available in salected
grades of input offset voltage and can be nulled with
one external potentiometer. Because the input
common-mode range extends to the negative rail and
the power consumption is extremely low, this family
is ideally suited for battery-powered or energyconserving applications. A bias-select pin can be used
to program one of three ac performance and powerdissipation levels to suit the application. The TLC251
offers the same operation sd the TLC271. but also
features guaranteed operation down to a 1 V supply.
Both devices are stable at unity gain.

description (continued)
These devices have internal electrostatic discharge (ESDI protection circuits that will prevent catastrophic failures
at voltages up to 2000 volts as tested under MIL-STD-SS3B, Method 3015.1. However, care should be exercised
in handling these devices as exposure to ESD may result in a degradation of the device parametric performance.
Because of the extremely high input impedance and low input bias and offset currents, applications for the TLC251
and TLC271 series inClude many areas that have previously been limited to BIFET and NFET product types. Any circuit
using high-impedance elements and requiring small offset errors is a good candidate for cost-effective use of these
devices. Many features associated with bipolar technology are available with LinCMOS operational amplifiers without
the power penalties of traditional bipolar dlh/ices. General applications such as transducer interfacing, analog calculations,
amplifier blocks, active filters, and signal buffering are all easily designed with the TLC271. Remote and inaccessible
equipment applications are possible using the low-voltage and low-power capabilities of the TLC2 51 . In addition, by
driving the bias-select input with a logic signal from a microprocessor, these operational amplifiers can have software. controlled performance and power consumption. The TLC251 is well suited to solve the difficult problems associated
with single-battery and solar-cell-powered applications .

TYPICAL APPLICATION INFORMATION
latchup avoidance
Junction-isolated CMOS circuits have an inherent parasitic PNPN structure that can function as an SCR. Under certain
conditions, this SCR may be triggered into a low-impedance state, resulting in excessive supply current. To avoid such
conditions, no voltage greater than 0.3 V beyond the supply rails should be applied to any pin. In general, the op amp supplies
should be applied simultaneously with, or before, application of any input signals.
using the bias select pin
The TLC251 and TLC271 have a bias select pin that allows the selection of one of three 100 conditions (10, 150, and
1000 p.A typical). This allows the user to trade-off power and ac performance. As shown in the typical supply current (1001
versus supply voltage (VOO) curves (Figure 4), the 100 varies only slightly from 4 to 16 V. Below 4 V, the 100 varies more
significantly. Note that the 100 values in the medium and low-bias modes at VOO = 1 V are typically 2 p.A, and in the
high mode are typically 12p.A. The following table shows the recommended bias select pin connections at VOO = 10 V:

description
The TLC252 and TLC272 series are low-cost. lowpower dual operational amplifiers designed to operate
with single or dual supplies. These devices utilize the
Texas Instruments silicon gate LinCMOSTM process.
giving them stable input offset voltages that are
available in selected grades of 2, 5 or 10 mV
maximum, very high input impedances, and extremely
low input offset and bias currents. Because the input
common-mode range extends to the negative rail and
the power consumption is extremely low, this series
is ideally suited for battery-powered or energyconserving applications. The TLC252 types offer
guaranteed operation down to a 1-V supply. All
devices are unity-gain stable and have excellent noise
characteristics.

description (continued)
These devices have internal electrostatic discharge (ESD) protection circuits that will prevent catastrophic failures
at voltages up to 2000 volts as tested under MIL-STD-8838, Method 3015.1. However, care should be exercised
in handling these devices as exposure to ESD may result in a degradation of the device parametric performance.

II
....

Because of the extremely high input impedance and low input bias and offset currents, applications for the TLC252
and TLC272 series include many areas that have previously been limited to BIFET and NFET product types. Any circuit
using high-impedance elements and requiring small offset errors is a good candidate for cost-effective use of these
devices. Many features associated with bipolar technology are available with LinCMOSTM operational amplifiers without
the power penalties of traditional bipolar devices. General applications such as transducer interfacing, analog calculations,
amplifier blocks, active filters, and signal buffering are all easily designed with the TLC252 and TLC272 series. Remote
and inaccessible equipment applications are possible using the low-voltage and low-power capabilities of the TLC252.
The TLC252 types are well suited to solve the difficult problems associated with single-battery and solar-i:ell-powered
applications. This series includes devices that are characterized for commercial, industrial, and military temperature
ranges and are available in 8-pin plastic and ceramic dual-in-line (DIP) packages, small outline (D) package, and chip
carrier (FH, FK) packages.

linCMOSTM DUAL OPERATIONAL AMPLIFIERS
TYPICAL APPLICATION INFORMATION
latchup avoidance
Junction-isolated CMOS circuits have an inherent parasitic PNPN structure that can function as an SCR. Under certain
conditions, this SCR may be triggered into a low-impedance state, resulting in excessive supply current. To avoid such
conditions, no voltage greater than 0.3 V beyond the supply rails should be applied to any pin. In general, the op amp supplies
should be established simultaneously with, or before, any input signals are applied.

output stage considerations
The amplifier's output stage consists of a source follower connected pullup transistor and an open drain pulldown transistor.
The high-level output voltage (VOH) is virtually independent of the 100 selection, and increases with higher values of VOO
and reduced output loading. The low-level output voltage (VOL) decreases with reduced output current and higher input
common-mode voltage. With no load, VOL is essentially equal to the GNO pin potential.

supply configurations
Even though the TLC252 and TLC272 are characterized for single-supply operation, they can be used effectively in a split
supply configuration if the input common-mode voltage (VICR), output swing (VOL and VOHI. and supply voltage limits
are not exceeded.

II

circuit layout precautions
The user is cautioned that whenever extremely high circuit impedances are used, care must be exercised in layout, construction,
board cleanliness, and supply filtering to avoid hum and noise pickup, as well as excessive OC leakages.

The TLC254 and TLC274 series are low-cost, lowpower quad operational amplifiers designed to operate
with single or dual supplies. These devices utilize the
Texas Instruments silicon-gate LinCMOSTM process,
giving them stable input offset voltages that are
available in selected grades of 2, 5 or 10 mV
maximum, very high input impedances, and extremely
low input offset and bias currents. Because the input
common-mode range extends to the negative rail and
the power consumption is extremely low, this series
is ideally suited for battery-powered or energyconserving applications. The TLC254 types offer
guaranteed operation down to a l-V supply. All
devices are unity-gain stable and have excellent noise
characteristics.

description (continued)
These devices have internal electrostatic discharge (ESDI protection circuits that will prevent catastrophic failures
at voltages up to 2000 volts as tested under MIL-STD-883B, Method 3015.1. However, care should be exercised
in handling these devices as exposure to ESD may result in a degradation of the device parametric performance.
Because of the extremely high input impedance and low input bias and offset currents, applications for the TLC254
and TLC274 series include many areas that have previously been limited to BIFET and NFET product types. Any circuit
using high-impedance elements and requiring small offset errors is a good candidate for cost-effective use of these
devices. Many features associated with bipolar technology are available with LinCMOSTM operational amplifiers without
the power penalties of tradjtional bipolar devices. General applications such as transdl,J£er interfacing, analog calculations,
amplifier blocks, active filters, and signal buffering are all easily designed with the TLC254 and TLC274 series. Remote
and inaccessible equipment applications are possible using the low-voltage and low-power capabilities of the TLC254.
The TLC254 types are well suited to solve the difficult problems associated with single-battery and solar-cell-powered
applicatioQs. This series includes devices that are characterized for commercial, industrial, and military temperature
ranges and are available in 14-pin plastic and ceramic dual-in-line (DIP) packages, small outline (D) package, and chip
carrier (FH, FK) packages .

NOTES: 1. All voltage values. except differential voltages, are with respect to network ground terminal.
2. Differentlsl voltages are at the noninverting Input terminal With respect to the Inverting Input terminal.
3. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure the maximum dissipation rating is

not exceeded.
4. For operation above 25 DC free-air temperature, refer to the Dissipation Derating Table.
5. For FH and FK packages, power rating and derating factor will vary with the actual mounting technique used. The values stated hee are belived
to be conservative.

o

The members of the TLC277 family are low-offsetvoltage, low-power, dual operational amplifiers
designed to operate with single or dual supplies. These
devices utilize the Texas Instruments silicon-gate
LinCMOS™ process, providing stable input offset
voltages, very high input impedances, and extremely
low input offset and bias currents. This series is ideally
suited for battery-powered or energy-saving
applications because the input common-mode range
includes the negative rail and the power comsumption
is extremely low.

These devices have internal electrostatic discharge
(ESDI protection circuits that will prevent catastrophic
failures at voltages up to 2000 volts as tested under
MIL-STD-8838, Method 3015.1. However, care
should be exercised in handling these devices as
exposure to ESD may result in a degradation of the
device parametric performance.

LinCMOSTM DUAL OPERATIONAL AMPLIFIERS
description (continued)
Because of the extremely high input impedance and low input bias and offset currents, applications for the TLC277
series include many areas that have previously been limited to BIFET and NFET product types. Any circuit using highimpedance elements and requiring small offset errors is a good candidate for cost-effective use of these devices. Many
features associated with bipolar technology are available with LinCMOS™ operational amplifiers without the power
penalties of traditional bipolar devices. General applications such as transducer interfacing, analog calculations, amplifier
blocks, active filters, and signal buffering are all easily designed with the TLC277 series. This series includes devices
that will be characterized for commercial, industrial, and military temperature ranges and will be available in B-pin
plastic and ceramic dual-in-line (P, JG) packages, small-outline (0) package, and chip carrier (FH, FK) packages.

LinCMOSTM DUAL OPERATIONAL AMPLIFIERS
TYPICAL APPLICATION INFORMATION
latchup avoidance
Junction-isolated CMOS circuits have an inherent parasitic PNPN structure that can function as an SCR. Under certain
conditions, this SCR may be triggered into a low-impedance state, resulting in excessive supply current. To avoid such
conditions, no voltage greater than 0.3 V beyond the supply rails should be applied to any pin. In general, the op amp supplies
should be established simultaneously with, or before, any input signals are applied.

output stage considerations
The amplifier's output stage consists of a source follower connected pullup transistor and an open drain pulldown transistor.
The high-level output voltaga (VOH) is virtually independent of the 100 selection. and increases with higher values of VOO
and reduced outl'lut loading. The low-Iavel output voltage (VoLl decreases with reduced output current and higher input
common-mode voltage. With no load. VOL is essentially equal to the GNO pin potential.

supply configurations
Even though the TLC277 is characterized for single-supply operation, it can be used effectively in a split-supply configuration
if the input common-mode voltage (VICR), output swing (VOL and VOH), and supply voltage limits are not exceeded.

circuit layout precautions

o

The user is cautioned that whenever extremely high circuit impedances are used, care must be exercised in layout, construction,
board cleanliness, and supply filtering to avoid hum and noise pickup, as well as excessive OC leakages.

U FLAT PACKAGE
(TOPVIEWl

The uA 702 is a high-gain, wideband operational
amplifier having differential inputs and single-ended
emitter-follower outputs. Provisions are incorporated
within the circuit whereby external components may
be used to compensate the amplifier for stable
operation under various feedback or load conditions.
Component matching, inherent in silicQn monolithic
circuit-fabrication techniques, produces an amplifier
with low-drift and low-offset characteristics. The
uA 702 is particularly useful for applications requiring
transfer or generation of linear and nonlinear functions
up to a frequency of 30 MHz.
The uA 702 is characterized for operation over the full
military temperature range of -55°C to 125°C.

description
These devices represent a breakthrough in operational amplifier performance. Low offset and long-term stability are
achieved by means of a low-noise. chopperless. bipolar-input-transistor amplifier circuit. For most applications. no
external components are required for offset nulling and frequency compensation. The true differential input. with a
wide input voltage range and outstanding common-mode rejection. provides maximum flexibility and performance
in high-noise environments and in non inverting applications. Low bias currents and extremely high input impedances
are maintained over the entire temperature range. The uA 714 is unsurpassed for low-noise. high-accuracy amplification
of very-low-level signals.

description
The uA 741 is a general-purpose operational amplifier
featuring offset-voltage null capability.
The high common-mode input voltage range and the
absence of latch-up make the amplifier ideal for
voltage-follower applications. The device is shortcircuit protected and the internal frequency
compensation ensures stability without external
components. A low potentiometer may be connected
between the offset null inputs to null out the offset
voltage as shown in Figure 2.
The uA 741 M is characterized for operation over the
full military temperature range of - 55 DC to 125 DC;
the uA 7 41 C is characterized for operation from 0 DC
to 70 D C.

The uA 7 48 is a general-purpose operational amplifier
that offers the same advantages and attractive
features as the uA 741 except for internal
compensation. External compensation can be as
simple as a 30-pF capacitor for unity-gain conditions
and. when the closed-loop gain is greater than one.
can be changed to obtain wider bandwidth or higher
slew rate. This circuit features high gain. large
differential and common-mode input voltage range.
and output short-circuit protection. Input offset
voltage adjustment can be provided by connecting a
variable resistor between the offset null pins as shown
in Figure 12.

GLOSSARY

Response Time

The interval between the application of an input step function and the instant at when the output crosses the logic
threshold voltage.
NOTE: The input step drives the comparator from some initial condition sufficient to saturate the output (or in the
case of high-to-Iow-Ievel response time, to turn the output off) to an input level just barely in excess of that required
to bring the output back to the logic threshold voltage. This excess is referred to as the voltage overdrive.

Strobe Release Time
The time required for the output to rise to the logic threshold voltage after the strobe terminal has been driven from
its active logic level to its inactive logic level.

description
The LM106, LM206, and LM306 are high-speed
voltage comparators with differential inputs, a lowimpedance high-sink-current 1100 mAl output, and
two strobe inputs, These devices detect low-level
analog or digital signals and can drive digital logic or
lamps and relays directly, Short-circuit protection and
surge-current limiting is provided,
The circuit is similar to a TL81 0 with gated output,
A low-level input at either strobe causes the output
to remain high regardless of the differential input,
When both strobe inputs are either open or at a high
logic level, the output voltage is controlled by the
differential input voltage, The circuit will operate with
any negative supply voltage between - 3 volts and
- 1 2 volts with little difference in performance,

description'
The LM111, LM211, and LM311 are single high-speed
voltage comparators. These devices are designed to
operate from a wide range of power supply voltage,
including ± 1 5-volt supplies for operational amplifiers
and 5-volt supplies for logic systems. The output
levels are compatible with most TTL and MOS circuits.
These comparators are capable of driving lamps or
relays and switching voltages up to 50 volts at
50 milliamperes. All inputs and outputs can be isolated
from system ground. The outputs can drive loads
referenced to ground, VCC + or VCC _. Offset
balancing and strobe capability are available and the
outputs can be wire-OR connected. If the strobe is
low, the output will be in the off state regardless of
the differential input. Although slower than the TL506
and TL514, these devices are not as sensitive to
spurious oscillations.

21N+

These devices consist of four independent voltage
comparators that are designed to operate from a single
power supply over a wide range of voltages. Operation
from dual supplies is also possible so long as the
difference between the two supplies is 2 volts to
36 volts and pin 3 is at least 1 .5 volts more positive
than the input common-mode voltage. Current drain
is independent of the supply voltage. The outputs can
be connected to other open-collector outputs to
achieve wired-AND relationships.

description
These devices consist of two independent voltage
comparators that are designed to operate from a single
power supply over a wide range of voltages. Operation
from dual supplies is also possible so long as the
difference between the two supplies is 2 volts to
36 volts and pin 8 is at least 1.5 volts more positive
than the input common-mode voltage. Current drain
is independent of the supply voltage. The outputs can
be connected to other open-collector outputs to
achieve wired-AND relationships.

description
The LM219 and LM319 each consists of two
high-speed precision comparators that operate
over a wide range of supply voltages. These
comparators are fully specified for power
supplies up to ± 1 5 volts, but are specifically
designed to operate from a single 5-volt digital
logic supply. Due to the uncommitted collector
at the outputs, the LM219 and LM319 are
compatible with TTL circuits. These comparators
are also well-suited for driving lamps and relays
at currents up to 25 milliamperes. The LM219
series features faster response times but greater
power dissipation than the LM111 series.

All voltage values, except differential voltages, are with respect to the appropriate comparator ground terminal unless otherwise specified.
Differential voltages are at the noninverting input terminal with respect to the inverting input terminal.
The magnitude of the input voltage must never exceed the magnttude of the supply voltage or 15 volts, whichever is less.
The output may be shorted to ground or to either power supply.
For operation above 25°C free-air temperature, refer to Dissipation Derating Curves, Section 2.

description
This device consists of four independent voltage
comparators that are designed to operate from a single
power supply over a wide range of voltages, Operation
from dual supplies Ls also possible so long as the
difference between the two supplies is 2 volts to
28 volts and pin 3 is at least 1.5 volts more positive
than the input common-mode voltage. Current drain
is independent of the supply voltage. The outputs can
be connected to other open-collector outputs to
achieve wired-AND relationships.

description
The TL506 is a dual high-speed comparator, with each
half having differential inputs, a low-impedance output
with high-sink-current capability (100 mAl, and two
strobe inputs. This device detects low-level analog or
digital signals and can drive digital logic or lamps and
relays directly. Short-circuit protection and surgecurrent limiting is provided,
The circuit is similar to a TL81 0 with gated output.
A low-level input at either strobe causes the output
to remain high regardless of the differential input.
When both strobe inputs are either open or at a high
logic level. the output voltage is controlled by the
differential input voltage. The circuit will operate with
any negative supply voltage between - 3 V and
- 12 V with little difference in performance.

tUnless otherwise noted, all characteristics are measured with the strobe open. Full range (MIN to MAX) for TL506M is -55°C to 125°e and for the TL506C
is ooe to 70 oe.
*These typical values are at VCC+ = 12 V, VCC- = -6 V, TA = 25°C.
NOTES: 6. The offset voltages and offset currents given are the maximum values required to drive the output down to the low range (VOL) or up to the
high range (VOH). Thus these parameters actually define an error band and take into account the worst-case effects of voltage gain and input
impedance.
7. Power supply currents are measured with the respective noninverting inputs and inverting inputs of both comparators connected in parallel. The
outputs are open.

description
The TL510 monolithic high-speed voltage
comparator is an improved version of the TL710
with an extra stage added to increase voltage
amplification and accuracy, and a strobe input
for greater flexibility_Typical voltage
amplification is 33,000_ Since the ouput cannot
be more positive than the strobe, a low-level
input at the strobe will cause the output to go
low regardless of the differential input_
Component matching, inherent in integrated
circuit fabrication techniques, produces a
comparator with low-drift and low-offset
characteristics. These circuits are particularly
useful for applications requiring an amplitude
discriminator, memory sense amplifier, or a highspeed limit detector.
The TL51 OM is characterized for operation over
the full military temperature range of - 55°C to
125°C; the TL510C is characterized for
operation from OOC to 70 o C_

tUnless otherwise noted, all characteristics are measured with the strobe open. Full range (MIN to MAX) for TL510M is - 55°C to 125°C and for the TL51 oe
is OOC to 700C.
J
+These typical values are at T A = 25°C.
§The algebraic convention, where the most-positive (least negative) limit is designated as maximum, is used in this data sheet for logic levels only, e.g., when
o V is the maximum, the minimum limit is a more-negative voltage.
NOTE 4: These characteristics are verified by measurements at the following temperatures and output voltage levels: for TL510M, Vo = 1.8 V at
TA = -55°C, Vo = 1.4 V at TA = 25°C, and Vo = 1 Vat TA = 125°C; for TL510e, Vo = 1.5 V at TA = ooe, Vo = 1.4 V at 25°C.
and Vo = 1.2 V at T A = 70°C. These output voltage levels where selected to approximate the logic threshold voltages of the types of digital
logic circuits these comparators are intended to drive.

NOTES: 6. The response time specified is for a 10Q·mV input step with 5-mV overdrive.
6. For testing purposes, the input bias conditions are selected to produce an output voltage of 1.4 V. A 6-mV overdrive is then added to the input
bi.8S voltage to produce an output voltage that rises above 1.4 V. The time interval is measured from the 50% point of the strobe voltage curve
to the point where the overdriven output voltage crosses the 1.4 V level.

description
The TL514 is an improved version of the TL 7 20
dual high-speed voltage comparator. When
compared with the TL 720, these circuits feature
higher amplification (typically 33,000) due to an
extra amplification stage, increased accuracy
because of lower offset characteristics, and
greater flexibility with the addition of a strobe
to each comparator. Since the output cannot be
more positive than the strobe, a low-level input
at the strobe will cause the output to go low
regardless of the differential input.

operation over the full military temperature range
of -55°C to 125°C, the TL514C is
characterized for operation from ooC to 70°C.

t Unless otherwise noted, all characteristics are measured with the strobe open. Full range (MIN to MAX) forTL514M is - 55°C to 125°C and for the TL514C
is COC to 70°C.

:t: The algebraic convention where the most-positive (least-negative) limit is designated as maximum, is used in this data sheet for logic levels only, e.g., when

o V is the maximum, the minimum limit is a more-negative voltage.
§These typical values are at TA = 25°C.
'SUpply current and power dissipation limits apply for each comparator.
NOTE 4: These characteristics are verified by measurements at the following temperatures and output voltage levels: for TL514M, Va = 1.8 V at
TA = -55°C, Va = 1.4 V at TA = 25°C, and Va = 1 Vat TA = 125°C; for TL514C, Va = 1.5 V at TA = COC, Va = 1.4 V at 25°C,
and Va = 1.2 V at TA = 7CoC. These output voltage levels were selected to approximate the logic threshold voltages of the types of digital
logic circuits these comparators are intended to drive.

6. For testing purposes, the input bias conditions are selected to produce an output voltage of 1.4 V. A

5~mV

overdrive is then added to the input

bias voltage to produce an output voltage that rises above 1.4 V. The time interval is measured from the- 50% point of the strobe voltage curve
to the point where the overdriven output voltage crosses the 1.4 V level.

description
The TL710 is a monolithic high-speed comparator
having differential inputs and a low-impedance output,
Component matching, inherent in silicon integrated
Circuit fabrication techniques, produces a comparator
with a low-drift and low-offset characteristics, These
circuits are especially useful for applications requiring
an amplitude discriminator, memory sense amplifier,
or a high-speed voltage comparator, The TL710M is
characterized for operation over the full military
temperature range of - 55°C to 125°C; the TL710C
is characterized for operation from OoC to 70°C,

The TL81 0 is an improved version of the TL 710 highspeed voltage comparator with an extra stage added
to increase voltage amplification and accuracy. Typical
amplification is 33,000. Component matching,
inherent in monolithic integrated circuit fabrication
techniques, produces a comparator with low-drift and
row-offset characteristics. These circuits are
particularly useful for applications requiring an
amplitude discriminator, memory sense amplifier, or

description
The TL811 is an improved version of the TL 711 highspeed dual-channel voltage comparator, Voltage
amplification is higher (typically 17,500) due to an
extra stage, increasing the temperature accuracy. The
output pulse width may be "stretched" by varying the
capacitive loading,

TL811M. , , U FLAT PACKAGE

Each channel has differential inputs, a strobe input,
and an output in common with the other channel.
When either strobe is taken low, it inhibits the
associated channel. If both strobes are simultaneously
low, the output will be low regardless of the conditions
applied to the differential inputs,
These dual-channel voltage comparators are
particularly attractive for applications requiring an
amplitude-discriminating sense amplifier with an
adjustable threshold voltage.

when 0 V is the maximum, the minimum limit is a more~negative voltage.
NOTES: 4. These characteristics are verified by measurements at the following temperatures and output voltage levels: for TL811M, Vo == 1.8 V at
TA == -55°C, Va == 1.4 VatTA = 25°C. and Va = 1 Vat TA = 125°C; forTL811C, Vo = 1.5 V atTA = OOC, Va = 1.4V atTA = 25°C,
and Vo = 1.2 V at 70°C. These output voltage levels were selected to approximate the logic threshold voltages of the types of digital logic
circuits these comparators are intended to drive.

NOTES: 6. The response time specified is for a 100-mV input step with 5-mV overdrive and is the interval between the input step function and the instant
when the output crosses 1.4 V.
7. For testing purposes, the input bias conditions are selected to produce an output vottage of 1.4 V. A 5-mV overdrive is then added to the input
bias voltage to produce an output voltage that rises above 1 .4 V. The time interval is measured from the 50% point on the strobe voltage waveform
to the instant when the overdriven output voltage crosses the 1.4-V level.

COMP 2 {
The TLB20 is an improved version of the TL720 dual
high-speed voltage comparator. Each comparator has
differential inputs and a low-impedance output. When
compared with the TL 720, these circuits feature high
amplification (typically 33,000) due to an extra
amplification stage and increased accuracy because
of lower offset characteristics. They are particularly
useful in applications requiring an amplitude
discriminator, memory sense amplifier, or a high-speed
limit detector,

description
This device is fabricated using LinCMOSTM technology and consists of two independent voltage comparators designed
to operate from a single power supply, Operation from dual supplies is also possible so long as the difference between
the two supplies is 2 to 18 volts, Each of these devices features extremely high input impedance (typically greater
than 10 12 ohms) allowing direct interfacing with high-impedance sources, The outputs are n-channel open-drain
configurations, and can be connected to achieve positive-logic wired-AND relationships,
These devices have, internal electrostatic discharge (ESD) protection circuits that will prevent catastrophic failures
at voltages up to 2000 volts as tested under MIL-STD-8838, Method 3015,1, However, care should be exercised
in handling these devices as exposure to ESD may result in a degradation of the device parametric performance,

description
The uA711 is a high-speed dual-channel
comparator with differential inputs and a lowimpedance output. Component matching,
inherent with silicon monolithic circuit fabrication
techniques, produces a comparator circuit with
low-drift and low-offset characteristics. An
independent strobe input is provided for each of
the two channels, which when taken low,
inhibits the associated channel. If both strobes
are simultaneously low, the output will be low
regardless of the conditions applied to the
differential inputs. The comparator output pulse
duration can be "stretched" by varying the
capacitive loading. These dual comparators are
particularly useful for applications requiring an
amplitude-discriminating sense amplifier with an
adjustable threshold voltage.
The uA 711 M is characterized for operation over
the full military temperature range of - 55°C
to 125°C; the uA711C is characterized for
operation from O°C to 70°C.

t Unless otherwise noted, all characteristics are measured with the strobe of the channel under test open. The strobe of the other channel is grounded. Full
range for uA711 M is - 55 DC to 125 DC and for the uA711 C is ODC to 70 DC.
~The algebraic convention, where the most~positive (least~negativel limit is designated as maximum, is used in this data sheet for logic levels only, e.g.,
when 0 V is the maximum, the minimum limit is a more~negative voltage.
NOTE 4: These characteristics are verified by measurements at the following temperatures and output voltage levels: for uA711 M, Va = 1.8 V at TA = - 55°C,
Va = 1.4 VatTA = 25°C, and Va = 1 V atTA = 125°C; for uA71 lC, Va= 1,5 Vat TA = O°C, Va = 1.4 V atTA = 25°C, and Va = 1.2 V
at 70°C. These output voltage levels were selected to approximate the logic threshold voltages of the types of digital logic circuits these comparators
are intended to drive.

NOTES: 5, The response time specified is for a 1OO~mV input step with 5~mV overdrive and is the interval between the input step func.don and the instant
when the output crosses 1.4 V.
6. For testing purposes, the input bias conditions are selected to produce an output voltage of 1.4 V. A 5~mV overdrive is then added to the input
bias voltage to produce an output voltage that rises above 1.4 V. The time interval is measured from the 50% point on the strobe voltage waveform
to the instant when the overdriven output voltage crosses the 1 .4·V level.

The MC1545 and MC1445 are general-purpose,
gated, dual-channel wideband amplifiers
designed for use in video-signal mixing and
switching. Channel selection is accomplished by
control of the voltage level at the gate. A high
logic level selects channel A; a low logic level
selects channel B. The un selected channel will
have a gain of one or less.

description
The MC3469 is a write-current controller designed to provide the entire interface for straddle-erase floppydisk heads. The write current can be varied over a wide range by varying the value of an external resistor
in series with a laser-trimmed internal resistor, and inner-track compensation is provided through the
WR CUR SEL pin. A constant write current of 3 mA is provided by a 10-kO resistor between Vref and
Iref when WR CUR SEL is low and 4 mA (an increase of 33%) when WR CUR SEL is high. Provisions are
also made for adjusting the duration of the degaussing cycle that occurs at the end of each write operation.

II

The MC3469 will be characterized for operation from OOC to 70°C.

U)

The MC3471 is a monolithic integrated write controller/head driver designed to provide the entire interface
between the write data and head-control inputs and the heads (write and erase) for either tunnel-erase
or straddle-erase floppy disk systems.
Provisions are made for selecting a range of accurately controlled write currents by varying the value of
an external resistor connected between pins 1 and 2. Provisions for head selection during both read and
write operations are also made. Degaussing the read/write head can be accomplished at the end of each
write operation by a capacitor attached from pin 1 to ground; the degaussing period is controlled by the
value of this capacitor. There are additional provisions for adjusting inner/outer track compensation, and
the delay from write gate to erase turn-on and turn-off.
Erase delays are controlled by driving the delay inputs D1 and D2 with standard TTL open-collector logic
(microprocessor compatible), or by using the external RC mode in which the delay is one time constant.
In addition, the
or erase.

iNHiBiT output is provided to

description
These devices are monolithic timing circuits
capable of producing accurate time· delays or
oscillation. In the time-delay or monostable mode
of operation, the timed interval is controlled by
a single external resistor and capacitor network.
In the astable mode of operation. the frequency
and duty cycle may be independently controlled
with two external resistors and a single external
capacitor.
The threshold and trigger levels are normally
two-thirds and one-third, respectively, of Vee.
These levels can be altered by use of the control
voltage terminal. When the trigger input falls
below the trigger level, the flip-flop is set and the
output goes high. If the trigger input is above the
trigger level and the threshold input is above the
threshold level, the flip-flop is reset and the
output is low. The reset input can override all
other inputs and can be used to initiate a new
timing cycle. When the reset input goes low, the
flip-flop is reset and the output goes low.
Whenever the output is low. a low-impedance
path is provided between the discharge terminal
and ground.

is low, application of a negative-going pulse to the trigger input sets the flip-flop (Q goes low), drives the
output high, and turns off 1 . Capacitor C is then charged through RA until the voltage across the capacitor
reaches the threshold voltage of the threshold input. If the trigger input has returned to a high level, the
output of the threshold comparator will reset the flip-flop (Q goes high), drive the output low, and discharge
C through 1 .

Monostable operation is initiated when the
trigger input voltage falls below the trigger
threshold. Once initiated, the sequence will
complete only if the trigger input is high at the
end of the timing interval. Because of the
threshold level and saturation voltage of 1, the
output pulse duration is approximately
tw = 1.1 RAC. Figure 12 is a plot of the time
constant for various values of RA and C. The
threshold levels and charge rates are both
directly proportional to the supply voltage, VCC.
The timing interval is therefore independent of
the supply voltage, so long as the supply voltage
is constant during the time interval.

a

Applying a negative-going trigger pulse
simultaneously to the reset and trigger terminals
during the timing interval will discharge C and
re-initiate the cycle, commencing on the positive
edge of the reset pulse. The output is held low
as long as the reset pulse is low. When the reset
input is not used, it should be connected to VCC
to prevent false triggering.

This astable connection results in capacitor
charging and discharging between the threshold-voltage
level (",a.67.Vee) and the trigger-voltage level (",a.33.Vee). As in the monostable circuit. charge and
discharge times (and therefore the frequency and duty cycle) are independent of the supply voltage.

The circuit shown in Figure 16 may be utilized to detect a missing pulse or abnormally long spacing between
consecutive pulses in a train of pulses. The timing interval of the monostable circuit is continuously
retriggered by the input pulse train as long as the pulse spacing is less than the timing interval. A longer
pulse spacing, missing pulse, or terminated pulse train will permit the timing interval to be completed,
thereby generating an output pulse as illustrated in Figure 17.

The operation of the timer may be modified by modulating the internal threshold and trigger voltages. This
is accomplished by applying an external voltage (or current) to the control,voltage pin. Figure 19 is a circuit
for pulse-width modulation. The monostable circuit is triggered by a continuous input pulse train and the
threshold voltage is modulated by a control signal. The resultant effect is a modulation of the output pulse
width, as shown in Figure 20. A sine-wave modulation signal is illustrated, but any wave-shape could be
used.

Many applications, such as computers, require signals for initializing conditions during start-up. Other
applications such as test equipment require activation of test signals in sequence. These timing circuits
may be connected to provide such sequential control. The timers may be used in various combinations
of astable or monostable circuit connections, with or without modulation, for extremely flexible waveform
control. Figure 23 illustrates a sequencer circuit with possible applications in many systems and Figure 24

The threshold and trigger levels are normally
two-thirds and one-third respectively of Vee.
These levels can be altered by use of the control
voltage terminal. When the trigger input falls
below trigger level. the flip-flop is set and the
output goes high, If the trigger input is above the
trigger level and the threshold input is above the
threshold level. the flip-flop is reset and the
output is low. The reset input can override all
other inputs and can be used to initiate a new
timing cycle, When the reset input goes low. the
flip-flop is reset and the output goes low.
Whenever the output is low. a low-impedance
path is provided between the discharge terminal
and ground.

35 feet away. Although gain can be increased by varying R1 (Figure 4), there is a limit to which the gain
can be increased for reliable module operation. This will vary from application to application. The modules
are "kitted" prior to their final test during manufacture. This is necessary because the desired gain
distribution is much narrower than the module gain distribution if all were kitted with one value resistor.
As kitted, these modules will perform satisfactorily in most applications. As a rule of thumb, the gain can
be increased by up to a factor of 4, if required, by increasing R1 correspondingly. Gain is directly proportional
to R1.

description
The TLOl 0 is a Wilson current mirror that provides output current in a selectable fixed ratio to the input current. The
ratio is substantially independent of changes in load, voltages, and temperature. Selecting the ratio consists of connecting
appropriate input emitter pins and output emitter pins to ground as shown in Figure 1.
The TL010 is designed to operate with up to 3 milliamperes input current if all three input emitter pins are used. It
will also operate at voltages up to 35 volts.
The TL0101 is characterized for operation from -40°C to 85°C, The TL010C is characterized for operation from
OOG to 70°C.

In this application of the Tl010, the problem is to measure a precise volume of liquid flowing through a line and shut off the flow with a relay when the
limit is reached. For the particular volume to be measured and the pressure detector used, a current gain of 11.9 is required. By setting the TL010 for a gain
of 10 with the emitter selection, the exact gain of 11.9 may be obtained by adjusting the pressure-time product control.

description
The TL011, TL012, TL014, and TL021 are Wilson current mirrors with output currents in fixed proportion to the input
currents and substantially independent of changes in voltage, load, and temperature, These devices make use of the
tight matching properties of identical bipolar transistors on a monolithic integrated circuit chip to achieve current-ratio
accuracy typically better than 98%.
Current mirrors are used extensively in linear integrated circuit designs as active loads for operational-amplifier stages
and as current sources for other stages. The TLO 11 family gives the designer this same capability with no sacrifice
in accuracy or stability.
The TL011, TL012, and TL014 are designed to .operate with input currents up to 1 milliampere and output voltage
up to 35 volts. The TL021 is designed for 2 milliamperes and 35 volts.

AGC¥

This device is a monolithic two-stage video
amplifier with differential inputs and outputs.

IN+

+

OUT+

Internal feedback provides wide bandwidth, low
INOUTphase distortion, and excellent gain stability.
Variable gain based on signal summation
REF
provides large AGe control over a wide
bandwidth with low harmonic distortion.
Emitter-follower outputs enable the device to drive capacitive loads. All stages are current-source biased
to obtain high common-mode and supply-voltage rejection ratios. The gain of 100 may "be electronically
attenuated as much as 50 dB at 60 MHz by applying a control voltage to the AGe pins. No external frequency
compensation components are required.

AGC

This device is particularly useful in TV and Radio IF and RF AGe circuits, as well as magnetic-tape and
disc-file systems where AGC is needed. Other applications include video and pulse amplifiers where a large
AGC range, wide bandwidth, low phase shift, and excellent gain stability are required.

The TL030 is a monolithic high-speed disk-memory
read amplifier fabricated with bipolar Schottky process
technology. The device consists of a diode selection
matrix comprised of write, read, and head diodes
preceding a video amplifier. The head read diode array
may be externally biased to select one of four-disk
memory heads. The resultant analog signal is then
amplified by the read amplifier and presented as
differential emitter-follower output voltages. The
TL030 is characterized for operation from ooC to
70°C.

The TL 172C is a low-cost magnetically operated
normally off electronic switch that utilizes the Hall
Effect to sense the presence of a magnetic field. Each
circuit consists of a Hall-Effect sensor, signal
conditioning and hysteresis functions, and an output
transistor integrated into a monolithic chip. A
magnetic field of sufficient strength in the positive
direction will cause the TL 1 72C output to be in a lowimpedance state. Otherwise the output will present
a high impedance. The output of this circuitry
can be connected to many different types of electronic
components.

The device is particularly useful in magnetic-tape
or disc-file systems using phase or NRZ encoding
and in high-speed thin-film or plated-wire
memories. Other applications include generalpurpose video and pulse amplifiers where wide
bandwidth, low phase shift, and excellent gain
stability are required.

description
The TL852 is an economical sonar ranging receiver integrated circuit for use with the TL851 control
integrated circuit. A minimum of external components is required for operation, and this amplifier easily
interfaces to Polaroid's 50-kilohertz electrostatic transducer. An external 68-kilohm ± 5% resistor from
pin 8 (Bias) to pin 16 (GND) provides the internal biasing reference. Amplifier gain can be set with a resistor
from pin 1 (GlIN) to pin 3 (GADJ). Required amplifier gain will vary for different applications. Using the
detect-level measurement circuit of Figure 1, a nominal peak-to-peak value of 230 millivolts input during
gain step 2 is recommended for most applications. For reliable operation, a level no lower than 50 millivolts
should be used. The recommended detect level of 230 millivolts can be obtained for most amplifiers with
an Rl value between 5 kilohms and 20 kilohms.
Digital control of amplifier gain is provided with gain control inputs on pins 12 through 15. These inputs
must be driven synchronously (all inputs stable within 0.1 microsecond) to avoid false receive output signals
due to invalid logic counts. This can be done easily with the TL851 control IC. A plot showing relative
gain for the various gain steps versus time can be seen in Figure 2. To dampen ringing of the 50-kilohertz
electrostatic transducer, a 5-kilohm resistor from pin 1 (GAIN) to pin 2 (XIN) is recommended.
An external parallel combination of inductance and capacitance between pin 4 (LC) and pin 5 (VCC) provides
an amplifier with an externally controlled gain and Q. This not only allows control of gain to compensate
for attenuation of signal with distance, but also maximizes noise and sidelobe rejection, Care must be taken
to accurately tune the L-C combination at operating frequency or gain and Q will be greatly reduced at
higher gain steps.

AC coupling between stages of the amplifier is accomplished with a O.Ol-microfarad capacitor for proper
biasing.
The receive output is normally held at a low level by an internal l-microampere current source. When an
input of sufficient amplitude is received, the output is driven alternately by the l-microampere discharge
current and a 50-microampere charging current. A 1OOO-picofarad capacitor is required from the receive
output (pin 9) to ground (pin 16) to integrate the received signal so that one or two noise pulses will not
be recognized.
Pin 2 (XIN) provides clamping for the transformer secondary when used for transducer transmit drive as
shown in Figure 4 of the SN28827 data sheet,

detect level vs gain step
Detect level is measured by applying a 15-cycle burst of 49.4 kilohertz square wave just after the beginning
of the gain step to be tested. The least burst amplitude that makes the REC pin reach the trip level is defined
to be the detect level. System gain is then inversely proportional to detect level. See the test circuit in
Figure 1.

description
The TLC551 is a monolithic timing circuit fabricated
using Tl's LinCMOSTM process. Due to its highimpedance inputs (typically 10 12 m, it is capable of
producing accurate time delays and oscillations while
using less-expensive, smaller timing capacitors than
the NE555. Like the NE555 , the TLC551 achieves
both monostable (using one resistor and one capacitor)
and astable (using two resistors and one capacitor)
operation, In addition, 50% duty cycle astable
operation is possible using only a single resistor and
one capacitor. The LinCMOSTM process allows the
TLC551 to operate at frequencies up to 2 MHz and
be fully compatible with CMOS, TTL, and MOS logic.
It also provides very low power consumption (typically
1 mW at VDD = 5 V) over a wide range of supply
voltages ranging from 1 volt to 18 volts,

Reset can override Trigger, which can override Threshold.

II

The threshold and trigger levels are normally two-thirds and one-third respectively of VDD, These levels can be altered
by use of the control voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set and the
output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level,
the flip-flop is reset and the output is low. The reset input can override all other inputs and can be used to initiate
a new timing cycle. When the reset input goes low, the flip-flop is reset and the output goes low. Whenever the output
is low, a low-impedance path is provided between the discharge terminal and ground.
While the CMOS output is capable of sinking over 100 mA and sourcing over 10 mA, the TLC551 exhibits greatly
reduced supply current spikes during output transitions. This minimizes the need for the large decoupling capacitors
required by the NE555.
The TLC551C is characterized for operation from OOC to 70°C.

Trigger can override Threshold.
the TLC552 and TLC556 achieve both monostable
(using one resistor and one capacitor) and astable
(using two resistors and one capacitor) operation. In
addition, 50% duty cycle astable operation is possible
using only a single resistor and one capacitor. The
LinCMOSTM process allows the TLC552 and TLC556
to operate at frequencies up to 2 MHz and be fully compatible with CMOS, TTL, and MOS logic. It also provides very
low power consumption (typically 2 mW at VDD = 5 V) over a wide range of supply voltages ranging from 1 volt
to 18 volts for the TLC552 and 2 volts to 18 volts for the TLC556.

The threshold and trigger levels are normally two-thirds and one-third respectively of VDD. These (evels can be altered
by use of the control voltage terminal. When the trigger input falls below trigger level, the flip-flop is set and the output
goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop
is reset and the output is low. The reset input can override all other inputs and can be used to initiate a new timing
cycle. When the reset input goes low, the flip-flop is reset and the output goes low. Whenever the output is low,
a low impedance path is provided between the discharge terminal and ground.
While the CMOS output is capable of sinking over 100 mA and sourcing over 10 mA, the TLC552 and TLC556 exhibit
greatly reduced supply current spikes during output transitions. This minimizes the need for the large decoupling
capacitors required by the NE556.
The TLC556M will be characterized for operation over the full military temperature range of - 55°C to 125°C. The
TLC552CM and TLC556C are characterized for operation from OOC to 70°C.

These devices have internal electrostatic discharge (ESD) protection circuits that will prevent catastrophic failures
at voltage up to 2000 volts as tested under MIL-STD-8838, Method 3015.1. However, care should be exercised in
handling these devices as exposure to ESD may result in a degradation of the device parametric performance.
All unused inputs should be tied to an appropriate logic level to prevent false triggering.
The TLC555M is characterized for operation over the full military temperature range of - 55°C to 125°C; the TLC555C
is characterized for operation from OOC to 70°C.

Internal series-shunt feedback provides wide bandwidth, low phase distortion, and excellent gain
stability. Emitter-follower outputs enable the device
to drive capacitive loads and all stages are currentsource biased to obtain high common-mode and
supply-voltage rejection ratios.
Fixed differential amplification of 10, 100, or 400
may be selected without external components, or
amplification may be adjusted from 10 to 400 by the
use of a single external resistor connected between

description
These circuits consist of a time-base oscillator, an eight-bit counter, a control flip-flop, and a voltage regulator. The
frequency of the time-base oscillator is set by the time constant of an external resistor and capacitor at pin 13 and
can be synchronized or modulatd by signals applied to the modulation input. The output of the time-base section is
applied directly to the input of the counter section and also appears at pin 14 (time base). The time-base pin may
be used to monitor the frequency of the oscillator, to provide an output pulse to other Circuitry, or (with the time-base
section disabled) to drive the counter input from an external source. The counter input is activated on a negativegoing transition. The reset input stops the time-base oscillator and sets each binary output, 00 through 07, and the
time-base output to a TTL high level. After resetting, the trigger input starts the oscillator and all 0 outputs go low.
Once triggered, the uA2240e will ignore any signals at the trigger input until it is reset.
The uA2240e timer/counter may be operated in the free-running mode or with output-signal feeedback to the reset
input for automatic reset. Two or more binary outputs may be connected together to generate complex pulse patterns,
or each output may be used separately to provide eight output frequencies. Using two circuits in cascade can provide
precise time delays of up to three years.

TYPICAL APPLICATION INFORMATION

Figure 5 shows voltage waveforms for typical
operation of the uA2240C. If both reset and trigger
inputs are low during power-up, the tim~r/counter will
be in a reset state with all binary (a) outputs high and
the oscillator stopped. In this state, a high level on the
trigger input starts the time-base oscillator. The initial
negative-going pulse from the oscillator sets the
outputs to low logic levels at the beginning of the first
time-base period. The uA2240C will ignore any further
signals at the trigger input until after a reset signal is
applied to the reset input. With the trigger input low,
a high level at the reset input will set a outputs high
and stop the time-base oscillator. If the reset signal
occurs while the trigger input is high, the reset is
ignored. If the reset input remains high when the
trigger input goes low, the uA2240C will reset.

TYPE uA2240C
PROGRAMMABLE TIMER/COUNTER

TYPICAL APPLICATION INFORMATION
In monostable applications of the uA2240C one or more of the binary outputs will be connected to the reset terminal
as shown in Figure 6. The binary outputs are open-collector stages that can be connected together to a common pullup resistor to provide a "wired-OR" function. The combined output will be low as long as anyone of the outputs
is low. This type of arrangemeht can be used for time delays that are· integer multiples of the time-base period. For
example, if 05 (2 5 = 321 only is connected to the reset input, every trigger pulse will generate a 32-period active-low
output. Similarly, if 00, 04, and 05 are connected to reset, each trigger pulse creates a 49-period delay.
In astable operation, the uA2240C will free-run from the time it is triggered until it receives an external reset signal.
The period of the time-base oscillator is equal to the RC time constant of an external resistor and capacitor connected
as shown in Figure 6 when the modulation input is open (approximately 3.5 volts internal, see Figure 4). Under conditions
of high supply voltage (VCC > 7 V) and low value of timing capacitor (C < d.1 I'F), the pulse duration of the timebase oscillator may be too short to properly trigger the counters. This situation can be corrected by adding a
300-picofarad capacitor between the time-base output and ground. The time-base output (TBO) is an open-collector
output that requires a 20-kll pull-up resistor to Pin 15 for proper operation. The time-base pin may also be used as
an input to the counters for an external time-base or as an active-low inhibit input to interrupt counting without resetting.

en
"C
~

(')

Ai"

-n
c

::::J

The modulation input varies the ratio of the time-base period to the RC time constant as a function of the dc bias
voltage (see Figure 4). It can also be used to synchronize the timer/counter to an external clock or sync signal.
The regulator output is used internally to drive the binary counters and the control logic. This terminal can also be
used to supply voltage to additional uA2240C devices to minimize power dissipation when several timer circuits are
cascaded. For circuit operation with an external clock, the regulator output can be used as the VCC input terminal
to power down the internal time base and reduce power dissipation. When supply voltages less than 4.5 volts are
used with the internal time base, Pin 15 should be shorted to Pin 16.

description

'3
C)

The LM217, and LM317 are adjustable 3-terminal positive-voltage regulators capable of supplying 1.5 amperes over
a differential voltage range of 3 volts to 40 volts. They are exceptionally easy to use and require only two external
resistors to set the output voltage. Both input and output regulation are better than standard fixed regulators. The
devices are packaged in a standard transistor package that is easily mounted and handled.

Go)
C)

...
CO

In addition to higher performance than fixed regulators, these regulators offer full overload protection available only
in integrated circuits. Included on the chip are current limit, thermal overload protection, and safe-area protection.
All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected. Normally,
no capacitors are needed unless the device is situated far from the input filter capacitors in which case an input bypass
is needed. An optional output capacitor can be added to improve transient response, The adjustment terminal can
be bypassed to achieve very high ripple rejection, which is difficult to achieve with standard 3-terminal regulators,

>

•

Besides replacing fixed regulators, these regulators are useful in a wide variety of other applications, The primary
applications of each of these regulators is that of a programmable output regulator, but by connecting a fixed resistor
between the adjustment terminal and the output terminal, each device can be used as a precision current regulator.
Even though the regulator is floating and sees only the input-to-output differential voltage, use of these devices to
regulate output voltages that would cause the maximum-rated differential voltage to be exceeded if the output became
shorted to ground is not recommended. The TL783 or TL783A is recommended for output voltages exceeding 37
volts. Supplies with electronic shutdown can be achieved by clamping the adjustment terminal to ground, which
programs the output to 1.2 volts where most loads draw little current.
The LM217 and LM317 are characterized for operation from - 25°C to 150°C and from

aoc to 125°C, respectively.

description
The LM237 and LM337 are adjustable 3-terminal negative-voltage regulators capable of supplying in excess of -1.5 A
over an output voltage range of -1.2 V to -37 V. They are exceptionally easy to use, requiring only two external
resistors to set the output voltage and one output capacitor for frequency compensation. The current design has been
optimized for excellent regulation and low thermal transients. In addition the LM237.and LM337 feature internal
current limiting, thermal shutdown, and safe-area compensation, making them virtually immune to blowout by
overloads.
The LM237 and LM337 serve a wide variety of applications including local on-card regulation, programmable output
voltage regulation, or precision current regulation. They are ideal complements to the LM217 and LM317 adjustable
positive-voltage regulators.

REGULATOR

description
The LM320 series of three-terminal, fixed-negative-voltage monolithic integrated circuit voltage regulators are designed
to provide a fixed output voltage of - 5 volts, - 12 volts, and - 1 5 volts with up to 1.5 amperes of output current.
Each is designed for a wide range of applications which includes on-card regulation for elimination of noise and distribution
problems associated with single-point regulation.
The internal current limiting and thermal shutdown features of these regulators make them essentially immune to
overload. The LM320, when used as a fixed-voltage regulator, needs only one external component: a compensation
capacitor at the output terminal. In addition, these devices can be used with external components to obtain adjustable
output voltages and currents or as the power-pass element in precision regulators.

description
The LM330 3·terminal positive regulator features an ability to source 150 milliamperes of output current with an inputoutput differential of 0.6 volt or less. Familar regulator features such as current limit and thermal overload protection
are also provided.
The LM330 has low dropout voltage making it useful for certain battery applications. For example. since the low dropout
voltage allows a longer battery discharge before the output falls out of regulation. a battery supplying the regulator
input voltage may discharge to 5.6 volts and still properly regulate the system and load voltage. The LM330 protects
both itself and the regulated system from reverse installation of batteries:

.....oca
rn

Other protection features include line transient protection above 40 volts, where the output actually shuts down to
avoid damaging internal and external circuits. The LM330 regulator cannot be harmed by temporary mirror-image
insertion.

NOTES: A. Use of C1 is required if the regulator is not locsted in close proximity to the supply filter.

B. Capacitor C2 must be located as close as possible to the regulator and may be an aluminum or tantalum type capacitor. The
minimum capacitance that will provide stabilitY is 10 ",F. The capacitor must be rated for operation at _40°C to guarantee
stability to that extreme.

description
This series of fixed-voltage monolithic integratedcircuit voltage regulators is designed for a wide range
of applications. These applications include on-card
regulation for elimination of noise and distribution
problems associated with single-point regulation. Any
of these regulators can deliver up to 1.5 amperes of
output current. The internal current limiting and
thermal shutdown features of these regulators make
them essentially immune to overload. In addition to
use as fixed-voltage regulators, these devices can be
used with external components to obtain adjustable
output voltages and currents and also as the powerpass element in precision regulators.

THE COMMON TERMINAL IS IN
ELECTRICAL CONTACT WITH
THE MOUNTING BASE

description
The LM350 is an adjustable 3-terminal positivevoltage regulator capable of supplying 3 amperes over
an output voltage range of 1.2 volts to 33 volts. The
device is easy to use and requires only two external
resistors to set the output voltage. Both input and
output regulation are better than standard fixed
regulators.

In addition to higher performance than fixed regulators. the LM350 offers full overload protection available only in
integrated circuits. Included on the chip current limit. thermal overload protection. and safe-area protection. All
overload protection circuitry remains fully functional even if the adjustment terminal is disconnected. Normally. no
capacitors are needed unless the device is situated far from the input filter capacitors in which case an input bypass
is needed. An optional output capacitor can be added to improve transient response. The adjustment terminal can
be bypassed to achieve very high ripple rejection. which is difficult to achieve with standard 3-terminal regulators.
Besides replacing fixed regulators. the LM350 is useful in a wide variety of other applications. Even though the regulator
is floating and sees only the input-to-output differential voltage. use of these devices to regulate voltages that would
cause the maximum-rated differential voltage to be exceeded if the output became shorted to ground is not
recommended. The TL783 or TL783A is recommended for output voltages exceeding 33 volts. The primary application
of the LM350 is that of a programmable output regulator. but by connecting a fixed resistor between the adjustment
terminal and the output terminal. this device can be used as a precision current regulator. Supplies with electronic
shutdown can be achieve by clamping the adjustment terminal to ground. which programs the output to 1.2 volts
where most loads draw little current.
The LM350 is characterized for operation from O°C to 125°C.

NOTES: 2. Input regulation is expressed as the percentage change in output voltage per 1 ~volt change at the input.
3. Input regulation and output regulation are measured using pulse techniques (t w s 10 pS, duty cycle :s 5%) to limit changes in average internal
dissipation. Output voltage changes due to large changes in internal dissipation must be taken into account separately.
4. Since long~term drift cannot be measured on the individual devices prior to shipment, this specification is not intended to be a guarantee or warranty.
It is an engineering estimate of the average drift to be expected from lot to lot.

description
The LM2930-5 and LM2930-8 are 3-terminal positive regulators that provide fixed 5-volt and 8-volt regulated outputs.
Each features the ability to source 150 milliamperes of output current with an input-output differential of 0.6 volt
or less. Familiar regulator fea,tures such as current limit and thermal overload protection are also provided.
The LM2930 series has low voltage dropout making it useful for certain battery applications. For example, the low
voltage dropout feature allows a longer battery discharge before the output falls out of regulation; the battery supplying
the regulator input voltage may discharge to 5.6 volts and still properly regulate the system and load voltage. Supporting
this feature, the LM2930 series protects both itself and the regulated system from reverse battery installation or twobattery jumps.

en
to..

...o

Other protection features include line transient protection for load-dump of up to 40 volts. In this case the regulator
shuts down to avoid damaging internal and external circuits. The LM2930 series regulator cannot be harmed by
temporary mirror-image insertion.

NOTES: A. Use of C1 is required if the regulator is not located in close proximity to the supply filter.
B. Capacitor C2 must be located as close as possible to the regulator and may be an aluminum or tantalum type capacitor. The minimum value

required for stability is 10 p.F. The capacitor must be rated for operation at -40°C to guarantee stability to that extreme.

description
The LM2931-5 is a 3-terminal positive voltage
regulator that provides a 5-volt regulated output.
It features the ability to source 1 50 milliamperes
of output current with an input-output
differential of 0.6 volt or less. Familiar regulator
features such as current limit and thermal
overload protection are also provided.

U
OUTPUT
The LM2931·5 has low voltage dropout making
it useful for certain battery applications. For
OCI
example, the low-voltage-dropout feature allows
TO·226AA
a longer battery discharge before the output falls
out of regulation; the battery supplying the
regulator input voltage may discharge to
5.6 volts and still properly regulate the system
and load voltage. Supporting this feature, the
LM2931-5 protects both itself and the regulated system from reverse battery installation or two-battery
jumps. The very low quiescent current feature is especially useful in battery powered applications.

Other protection features include line transient protection for load-dump of up to 60 volts. In this case
the regulator shuts down to avoid damaging internal and external circuits. The LM2931-5 regulator is virtually
immune to temporary mirror-image insertion.
The LM2931-5 is characterized for operation from -40°C to 150°C.

description
The MC3423 overvoltage-sensing circuit is designed to protect sensitive electronic circuitry by monitoring the supply
rail and triggering an external "crowbar" SCR in the event of a voltage transient or loss of regulation, The protective
mechanism may be activated by an overvoltage condition at the Sense 2 input or by application of a TTL high level
to the Remote Activate terminal. Separate outputs are available to trigger-the crowbar circuit and to provide a logic
pulse to indicator or power supply control circuitry _The Sense 2 input provides a direct control of the output circuitry.
The Sense 1 input controls an internal current source that may be utilized to implement a delayed trigger by connecting
its output to an external capacitor and the Sense 2 input_ This protects against false triggering due to noise at the
Sense 1 input_
The MC3423 is characterized for operation from O°C to 70 oC_

description
This series of fixed-voltage monolithic integratedcircuit voltage regulators is designed for a wide range
of applications. These include on·card regulation for
elimination of noise and distribution problems
associated with single'point regulation. In addition,
they can be used to control series pass elements to
make high-current voltage-regulator circuits. One of
these regulators can deliver up to 100 mA of output
current. The internal current-limiting and thermalshutdown features make them essentially immune to
overload. When used as a replacement for a Zenerdiode and resistor combination, these devices can
provide an effective improvement in output impedance
of two orders of magnitude and lower bias current.

description
The MC35060 and MC34060 incorporate on a single monolithic chip all the functions required in the construction
of a pulse-width-modulation control circuit. Designed primarily for power supply control, each of the devices contains
an on-chip 5-volt regulator, two error amplifiers, an adjustable oscillator, and a dead-time control comparator, The
uncommitted output transistor provides either common-emitter or emitter-follower output capability. The internal
amplifiers exhibit a common-mode voltage range from - 0.3 volt to VCC - 2 volts. The dead-time control comparator
has a fixed offset that provides approximately 5% dead time unless externally altered. The on-chip oscillator may
be bypassed by terminating RT (pin 6) to the reference output and providing a sawtooth input to CT (pin 5), or it
may be used to drive the common MC35060 or MC34060 circuitry and provide a sawtooth input for associated control
circuitry in multiple rail power supplies.

.
...
fI)

o

The MC35060 is characterized for operation over the full military temperature range of - 55 DC to 125 DC. The MC34060
is characterized for operation from 0 DC to 70 DC.

description
The SG 1524, SG2524, and SG3524 incorporate on
single monolithic chips all the functions required
in the construction of a regulating power supply,
inverter, or switching regulator. They can also be
used as the control element for high·power-output
applications. The SG 1524 family was designed for
switching regulators of either polarity, transformercoupled dc-to-dc converters, transformerless voltage
doublers, and polarity converter applications employing fixed-frequency, pulse-width-modulation techniques. The complementary output allows either
single-ended or push-pull application. Each device
includes an on-chip regulator, error amplifier, programmable oscillator, pulse-steering flip-flop, two
uncommitted pass transistors, a high-gain comparator,
and current-limiting and shut-down circuitry.

REGULATING PULSE WIDTH MODULATORS
PRINCIPLES OF OPERATION
The SG1524 t is a fixed-frequency pulse-width-modulation voltage-regulator control circuit. The regulator operates at a
fixed frequency that is programmed by one timing resistor RT and one timing capacitor CT. RT establishes a constant
charging current for CT. This results in a linear voltage ramp at CT, which is fed to the comparator providing linear
control of the output pulse width by the error amplifier. The SG 1524 contains an on-board 5·volt regulator that serves
as a reference as well as supplying the SG1524's internal regulator control circuitry. The internal reference voltage is
divided externally by a resistor ladder network to provide a reference within the common-mode range of the error amp·
lifier as shown in Figure 6, or an external reference may be used. The output is sensed by a second resistor divider net·
work and the error signal is amplified. This voltage is then compared to the linear voltage ramp at CT. The resulting
modulated pulse out of the high-gain comparator is then steered to the appropriate output pass transistor (01 or 02)
by the pulse-steering flip-flop, which is synchronously toggled by the oscillator output. The oscillator output pulse also
serves as a blanking pulse to assure both outputs are never on simultaneously during the transition times. The width of
the blanking pulse is controlled by the value of CT. The outputs may be applied in a push-pull configuration in which
their frequency is half that of the base oscillator, or paralleled for single-ended applications in which the frequency is
equal to that of the oscillator. The output of the error amplifier shares a common input to the comparator with the
current-limiting and shut-down circuitry and can be overridden by signals from either of these inputs. This common
point is also available externally and may be employed to control the gain of, or to compensate, the error amplifier, or
to provide additional control to the regulator.

Practical values of CT fall between 0.001 and 0.1 microfarad. Practical values of RT fall between 1.8 and 100 kilohms.
This results in a frequency range typically from 140 hertz to 500 kilohertz.

blanking

C/I

The output pulse of the oscillator is used as a blanking pulse at the output. This pulse width is controlled by the value
of CT as shown in Figure 5. If small values of CT are required, the oscillator output pulse width may still be maintained
by applying a shunt capacitance from pin 3 to ground.

synchronous operation
When an external clock is desired, a clock pulse of approximately 3 volts can be applied directly to the oscillator output
terminal. The impedance to ground at this point is approximately 2 kilohms. In this configuration RT CT must be
selected for a clock period slightly greater than that of the external clock.
If two or more SG1524 regulators are to be operated synchronously, all oscillator output terminals should be tied
together. The oscillator programmed for the minimum clock period will be the master from which all the other
SG 1524's operate. In this application, the CT RT values of the slaved regulators must be set for a period approximately
10% longer than that of the master regulator. In addition, CT (master) = 2 CT (slave) to ensure that the master output
pulse, which occurs first, has a wider pulse width and will subsequently reset the slave regulators.

The 5-volt internal reference may be employed by use of an external resistor divider network to establish a reference

error amplifier

C»
Q)

The error amplifier is a differential-input transconductance amplifier. The output is available for de gain control or ac
phase compensation. The compensation node (pin 9) is a high-impedance node (R L = 5 megohms). The gain of the
amplifier is AV = (0.002 n -1) RL and can easily be reduced from a nominal 10,000 by an external shunt resistance
from pin 9 to ground. Refer to Figure 3 for data.

Q)
C)

...
IV

'0

>

Pin 9, as discussed above, is made available for compensation. Since most output filters will introduce one or more
additional poles at frequencies below 200 hertz, which is the pole of the uncompensated amplifier, introduction of
a zero to cancel one of the output filter poles is desirable. This can best be accomplished with a series RC
circuit from pin 9 to ground in the range of 50 kilohms and 0.001 microfarads. Other frequencies can be canceled by
use of the formula f '" l/RC.

6

shut down circuitry
Pin 9 can also be employed to introduce external control of the SG1524. Any circuit that can sink 200 microamperes
can pull the compensation terminal to ground and thus disable the SG 1524.
In addition to constant-current limiting, pins 4 and 5 may also be used in transformer-coupled circuits to sense primary
current and shorten an output pulse should transformer saturation· occur. Pin 5 may also be grounded to convert pin 4
into an additional shutdown terminal.

description
The SG 1 525A/SG 1 527 A series of pulse-width modulation integrated circuits are designed to offer improved performance
and lower external parts count when used to implement various types of switching power supplies. Each device includes
an on-chip 5.1-volt reference, error amplifier, programmable oscillator, pulse-steering flip-flop, a latched comparator
under-voltage lockout, shutdown circuitry, and complementary source or sink outputs. The on-chip 5.l-volt reference
is trimmed to ± 1 % initial accuracy, serves as a reference output, and supplies the internal regulator control circuitry.
The input common-mode range of the error amplifier includes the reference voltage, which eliminates the need for
external divider resistors.

The oscillator operates at a fixed frequency determined by one timing resistor RT and one timing capacitor CT. The
timing resistor establishes the constant charging current for CT, resulting in a linear voltage ramp at CT. which is
fed to the PWM comparator providing linear control of the output pulse duration by the error amplifier. A Sync input
to the oscillator allows for external synchronization or for multiple units to be slaved together. A single external resistor
between the CT pin and the Discharge pin provides a wide range of dead-time adjustment. These devices also feature
built-in soft-start circuitry that requires only an external timing capacitor. The Shutdown pin controls both the softstart and the output drivers, and provides instantaneous turn-Ooff with soft-start recycle for slow turn-on. The softstart and output driver circuitry are also controlled by the under-voltage lockout circuit, which, during low-input supply
voltage of less than that required for normal operation, keeps the soft-start capacitor discharged and the output drivers
off.

Another unique feature is the S-R latch following the PWM compa.rator. This feature enables the output drivers to
be turned off any time the PWM pulse is terminated. The latch is reset with each clock pulse. However, the PWM
outputs will remain turned off for the duration of the period if the PWM comparator output is in a low-level state.
The SG1525A, SG2525A. and SG3525A output stages feature NOR logic, resulting in a low output for an off-state.
The SG1527A, SG2527A, and SG3527A output stages feature OR logic, resulting in a high-level output for an offstate. The output stages are totem-pole designs capable of sourcing or sinking 200 milliamperes of output current.
The SG l525A and SG 1527A are characterized for operation over the full military temperature range of - 55°C to
125°C. The SG2525A and SG2527A are characterized for operation from -25°C to 85°C. The SG3525A and
SG3527 A are characterized for operation for ooC to 70°C.

TYPICAL APPLICATION DATA
shutdown options
1.

Use an external transistor or open-collector comparator to pull down on the Compensation terminal (Pin 9). This
will set the PWM latch and turn off both driver outputs. If the shutdown signal is momentary. pulse-by-pulse protection
will be accomplished as the PWM latch is reset with each clock pulse.

2.

The same results may be accomplished by pulling down on the Soft-Start terminal (Pin 8) with the only difference
being that on this pin shutdown will not affect the amplifier compensation network, but must discharge any softstart capacitance.

3.

Application of a positive-going signal to the Shutdown terminal (Pin 10) will provide the most rapid shutdown of
the driver outputs but will not immediately set the PWM latch if there is a capacitor at the Soft-Start terminal. The
capacitor will discharge but at a current twice the charging current, The PWM latch can be set on a pulse-by-pulse
basis by the shutdown terminal if there is no external capacitance on the Soft-start terminal (Pin 8). Slow turn-on
may still be accomplished by connecting an external capacitor, blocking diode, and charging resistor to the
Compensation terminal (Pin 9).

description

a:

The TL317 is an adjustable 3·terminal positive·voltage regulator capable of supplying 100 milliamperes over an
output·voltage range of 1.2 volts to 32 volts. It is exceptionally easy to use and requires only two external resistors to
set the output voltage. Both input and output regulation are better than standard fixed regulators. The device is pack·
aged in standard packages that are easily mounted and handled.
In addition to higher performance than fixed regulators, this regulator offers full overload protection available only in
integrated circuits. Included on the chip are current limit and thermal overload protection. All overload protection
circuitry remains fully functional even if the adjustment terminal is disconnected. Normally, no capacitors are needed
unless the device is situated far from the input filter capacitors in which case an input bypass is needed. An optional
output capacitor can be added to improve transient response. The adjustment terminal can be bypassed to achieve very
high ripple rejection, which is difficult to achieve with standard 3·terminal regulators.

•

Besides replacing fixed regulators, the regulator is useful in a wide variety of other applications. Since the regulator
is floating and sees only the input·to·output differential voltage, supplies of several hundred volts can be regulated as
long as the maximum input·to·output differential is not exceeded. Its primary application is that of a programmable
output regulator, but by connecting a fixed resistor between the adjustment terminal and the output terminal, this
device can be used as a precision current regulator. Supplies with electronic shutdown can be achieved by clamping the
adjustment terminal to ground, which programs the output to 1.2 volts where most loads draw little current.
The TL317M is characterized for operation over the full military temperature range from -55°C to 125°C. The
TL317C is characterized for operation from O°C to 125°C.

description
The TL431 is a three-terminal adjustable regulator series with guaranteed thermal stability over applicable temperature
ranges. The output voltage may be set to any value between Vref (approximately 2.5 volts) and 36 volts with two
external resistors (see Figure 16). These devices have a typical dynamic output impedance of 0.2 n. Active output
circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for zener diodes in
many applications.
The TL431 M is characterized for operation over the full military temperature range of _55°C to 125°C. The TL431 I is
characterized for operation from _40°C to 85°C. and the TL431 C from O°C to 70°C.

description
The. TL493, TL494, and TL495 each incorporate on
a single monolithic chip all the functions required in
the construction of a pulse-width-modulation control
circuit. Designed primarily for power supply control,
these devices offer the systems engineer the flexibility
to tailor the power supply control circuitry to his
application,
The TL493 contains an error amplifier, current-limiting
amplifier, an on-chip adjustable oscillator, a dead-time
control comparator, pulse-steering control flip-flop, a
5-volt, 1 %-precision regulator, and output-control
circuits.
The error amplifier exhibits a common-mode voltage
range from -0,3 volts to VCC - 2 volts. The currentlimit amplifier exhibits a common-mode voltage range
from - 0.3 volts to 3 volts with an offset voltage of
approximately 80 millivolts in series with the inverting
input to ease circuit design requirements. The deadtime control comparator has a fixed offset that
provides approximately 5% dead time when externally
altered, The on-chip oscillator may be bypassed by
terminating RT (pin 6) to the reference output and
providing a sawtooth input to CT (pin 5), or it may
be used to drive the common circuits in synchronous
multiple-rail power supplies,

PULSE·WIDTH·MODULATION CONTROL CIRCUITS
description (continued)
The uncommitted output transistors provide either common-emitter or emitter-follower output capability. Each device
provides for push-pull or single-ended output operation, which may be selected through the output-control function.
The architecture of these devices prohibits the possibility of either output being pulsed twice during push-pull operation.
The TL493 and TL494 are similar except that an additional error amplifier is included in the TL494 instead of a currentlimiting amplifier. The TL495 provides the identical functions found in the TL494. In addition, it contains an on-chip
39-volt zener diode for high-voltage applications where VCC is greater than 40 volts, and an output-steering control
that overrides the internal control of the pulse-steering flip-flop.
The TL494M is characterized for operation over the full military temperature range from - 55°C to 125°C. The TL4941
is oharacterized for operation from - 25°C to 85 °C. The TL493C, TL494C, and TL495C are characterized for operation
from ooC to 70°C.

description
The TL496 power supply control" circuit is designed to provide a 9-volt regulated supply from a variety of input
sources. Operable from a 1- or 2-cell-battery input, the TL496 performs as a switching regulator with the addition of a
single inductor and filter capacitor. When ac coupled with a step-down transformer, the TL496 operates as a series
regulator to maintain the regulated output voltage and, with the addition of a single catch diode, time shares to
recharge the input batteries.
The design of the TL496 allows minimal supply current drain during stand-by operation (125 IJ.A typical). With most
battery sources this allows a constant bias to be maintained on the power supply. This makes power instantly available
to the system thus eliminating power-up sequencing problems.

9·VOLT POWER·SUPPLY CONTROLLER
functional description
'The iL496 is designed to operate from either a single-cell or two-cell source. To operate the device from a single cell
(1.1 V to 1.5 V) the source must be connected to both inputs lC and 2C as shown in Figure 1. For two-cell operation
(2.3 V to 3.0 Vl, the input is applied to the 2C input only and the lC input is left open (see Figure 2).
battery operation
The TL496 operates as a switching regulator from a battery input. The cycle is initiated when a low voltage condition is
sensed by the internal feedback (the thresholds at pin 1 and pin 8 are approximately 7.2 and 8.6 volts respectively). An
internal latch is set and the output transistor is turned "on." This causes the current in the external inductor (L) to
increase linearly until it reaches a peak value of approximately 1 ampere. When the peak current is sensed the internal
latch is reset and the output transistor ,is turned "off." The energy developed in the inductor is then delivered to the
output storage capacitor through the blocking diode. The latch remains in the off state until the feedback signal
indicates the output voltage is again deficient.
transformer-coupled operation

<
o
::+
Q)

The TL496 operates on alternate half cycles of the ac input during transformer-coupled operation to, first, sustain the
output voltage and, second, recharge the batteries. The TL496 performs like a series regulator to supply charge to the
output filter/storage capacitor during the first half cycle. The output voltage of the series regulator is slightly higher
voltage than that created by the switching circuit; this maintains the feedback voltage above the switching regulator
control circuit threshold. This effectively inhibits the switching control circuitry. During the second half cycle an
external diode (1 N4001) is used to clamp the negative going end of the transformer secondary to ground thus allowing
the positive-going end (end connected to V+ side of battery) to pump charge into the stand-by batteries.

description
The TLC497 A incorporates on a single monolithic chip all the active functions required in the construction of a switching
voltage regulator. It can also be used as the control element to drive external components for high-power-output
applications. The TL497 A was designed for ease of use in step-up, step-down, or voltage inversion applications requiring
high efficiency.
The TL497 A is a fixed-on·time variable-frequency switching voltage regulator control circuit, The on-time is
programmed by a single external capacitor connected between the frequency control pin and ground. This capacitor,
CT, is charged by an internal constant-current generator to a predetermined threshold. The charging current and the
threshold vary proportionally with VCC, thus the one time remains constant over the specified range of input voltage
(5 to 12 volts). Typical on-times for various values of CT are as follows:

...oen

c:

TIMING CAPACITOR, CT (pF)

II
01
CO

The output voltage is controlled by an external resistor ladder network (Rl and R2 in Figures 1, 2, and 3) that provides
a feedback voltage to the comparator input. This feedback voltage is compared to the reference voltage of 1.2 volts
(relative to the substrate pin) by the high·gain comparator. When the output voltage decays below the value required to
maintain 1,2 V at the comparator input, the comparator enables the oscillator circuit, which charges and discharges CT
as described above, The internal pass transistor is driven on during the charging of CT. The internal transistor may be
used directly for switching currents up to 500 milliamperes. Its collector and emitter are uncommitted and it is current
driven to allow operation from the positive supply voltage or ground. An internal Schottky diode matched to the
current characteristics of the internal transistor is also available for blocking or commutating purposes. The TL497A
also has on-chip current-limit circuitry that senses the peak currents in the switching regulator and protects the inductor
against saturation and the pass transistor against overstress. The current limit is adjustable and is programmed by a
single sense resistor, RCL, connected between pin 14 and pin 13, The current-limit circuitry is activated when 0.7 volt
is developed across RCL. External gating is provided by the inhibit input. When the inhibit input is high, the output is
turned off.

"0

>

Simplicity of design is a primary feature of the TL497 A. With only six external components (three resistors, two
capacitors, and one inductor), the TL497A will operate in numerous voltage conversion applications (step-up, step·
down, invert) with as much as 85% of the source power delivered to the load. The TL497 A replaces the TL497 in all
applications.
The TL497AM is characterized for operation over the full military temperature range of _55°C to 125°C, the TL497AI
is characterized for operation from _25°C to 85°C, and the TL497AC from O°C to 70°C.

description
The TL499C is a monolithic integrated circuit designed to provide regulated supply voltages. The regulated
voltage can be set to any value between 2.9 volts and 30 volts by adjusting two external resistors.
When the TL499C is ac coupled to line power through a step-down transformer. it operates as a series
dc voltage regulator to maintain the regulated output voltage. With the addition of a backup battery of
from 1.1 volts to 25 volts. an inductor. a filter capacitor. and two resistors. the TL499C will operate as
a step-up switching regulator during an ac line failure.
The adjustable regulated output voltage makes the TL499C useful for a wide range of applications. Providing
backup power during an ac line failure makes the TL499 extremely useful as backup power in microprocessor
memory applications.

description
The TL5BO is a monolithic, micro power, dual-switching regulator designed for use in battery applications. The output
voltage of each channel is adjustable. Floating the special pin, SYNC B, causes Channel B to be synchronized to the
oscillator in the same manner as Channel A. Shorting SYNC B to ground blocks the oscillator from Channel B, then
Channel B becomes a single-input comparator for low-battery indicator detection.
Both Channel A and Channel B are referenced to a band-gap generator. An external capacitor on the CT input (Pin 2)
sets the oscillator frequency between 100 hertz and 160 kilohertz.
The TL5BOC can attain up to BO-percent efficiency while operating over a supply voltage range of 2.4 volts to 30 volts
at an ultra low bias current of 140 microamperes.
The TL5BOC is characterized for operation from OoC to 70°C.

description
The TL593. TL594. and TL595 devices. each
incorporate on a single monolithic chip all the functions
required in the construction of a pulse-widthmodulation control circuit. Designed primarily for
power supply control. these devices offer the systems
engineer the flexibility to tailor the power supply
control circuitry to his application. The TL593. TL594.
and TL595 are improved direct replacements for the
TL493. TL494. and TL495.
The TL593 contains an error amplifier. current-limiting
amplifier. an on-chip adjustable oscillator. a dead-time
control comparator. pulse-steering control flip-flop.
5-volt regulator with a precision of 1 %. an undervoltage lockout control circuit. and output control
circuitry.
The error amplifier exhibits a common-mode voltage
range from - 0.3 volts to Vee - 2 volts. The currentlimit amplifier exhibits a common-mode voltage range
from -0.3 volts to Vee -6 volts with an offset
voltage of approximately 80 millivolts in series with
the inverting input to ease circuit design requirements.
The dead-time control comparator has a fixed offset
that provides approximately 5% dead time when
externally altered. The on-chip oscillator may be
bypassed by terminating RT (pin 6) to_the reference
output and providing a sawtooth input to eT
(pin 5). or it may be used to drive the common circuitry
in synchronous multiple-rail power supplies.

PULSE·WIDTH·MODULATION CONTROL CIRCUITS
description (continued)
The uncommitted output transistors provide either common-emitter or emitter-follower output capability. Each device
provides for push-pull or single-ended output operation with selection by means of the output-control function. The
architecture of these devices prohibits the possibility of either output being pulsed twice during push-pull operation.
The under-voltage lockout control circuit locks the outputs off until the internal circuitry is operational.
The TL593 and TL594 are similar except that an additional error amplifier is included in the TL594 instead of a currentlimiting amplifier. The TL595 provides the identical functions found in the TL594. In addition, the TL595 also contains
an on-chip 39-volt zener diode for high-voltage applications where Vce is greater than 40 volts, and an output steering
control that overrides the internal control of the pulse-steering flip-flop.
The TL593M and TL594M are ch'aracterized for operation over the full military temperature range from - 55 DC to
125 DC. The TL5941 is characterized for operation from - 25 DC to 85 DC. The TL593C, TL594C, and TL595C are
characterized for operation from 0 DC to 70 DC.

description
Each fixed-voltage precIsIon regulator in this series
is capable of supplying 1_5 amperes of load current_
A unique temperature-compensation technique
coupled with an internally trimmed bandgap reference
has resulted in improved accuracy when compared
to other three-terminal regulators_ Advanced layout
techniques provide excellent line, load, and thermal
regulation. The internal current limiting and thermal
shutdown features make the de~ices essentially
immune to overload.

description
The TL783 is an adjustable 3-terminal positive-voltage regulator with an output range of 1.25 volts to 125 volts and a
DMOS output transistor capable of sourcing more than 700 milliamperes, It is designed for use in high-voltage applications where standard bipolar regulators cannot be used. Excellent performance specifications , .. superior to those
of most bipolar regulators ... are achieved through circuit design and advanced layout techniques.
As a state-of-the-art regulator, the TL783 combines standard bipolar circuitry with high·voltage double-diffused MOS
transistors on one chip to yield a device capable of withstanding voltages far higher than standard bipolar integrated
circuits. Because of its lack of secondary breakdown and thermal runaway characteristics usually associated with bipolar
outputs, the TL7B3 maintains full overload protection while operating at up to 125 volts from input to output. Other
features of the device include current limiting, safe·operating-area (SOA) protection, and thermal shutdown. Even if
the adjustment pin is inadvertently disconnected, the protection circuitry remains functional.

Only two external resistors are required to program the output voltage, An input bypass capacitor is necessary only
when the regulator is situated far from the input filter. An output capacitor, although not required, will improve
transient response and protection from instantaneous output short-circuits. Excellent ripple rejection can be achieved
without a bypass capacitor at the adjustment terminal.

TYPE TL783C
HIGH·VOLTAGE ADJUSTABLE REGULATOR
DESIGN CONSIDERATIONS
The internal reference (see functional block diagram) is used to generate 1.25 volts nominal (Vref) between the output
and adjustment terminals. This voltage is developed across R1 and causes a constant current to flow through R1 and
the programming resistor R2, giving an output voltage of:
Vo = Vref (1 + R2/Rl) + ladj (R2)
or
Vo '" Vref (1 + R2/Rl).
The TL783 was designed to minimize ladj and maintain consistency over line and load variations, thereby minimizing
the ladj (R2) error term.
To maiiltain ladj at a low level, all quiescent operating current is returned to the output terminal. This quiescent
current must be sunk by the external load and is the minimum load current necessary to prevent the output from
rising. The recommended R1 value of 82 ohms will provide a minimum load current of 15 milliamperes. Larger values
may be used if the input·to·output differential voltage is less than 125 volts (see minimum operating current curve)
or if the load will sink some portion of the minimum current.
Bypass capacitors
The TL783 regulator is stable without bypass capacitors; however, any regulator will become unstable with certain
values of output capacitance if an input capacitor is not used. Therefore, the use of input bypassing. is recommended
whenever the regulator is located more than four inches from the power-supply filter capacitor. A l·microfarad tantalum
or electrolytic capacitor is usually sufficient.

<
o
::+

Adjustment·terminal capacitors are not recommended for use on the TL783 because they can seriously degrade load
transient response as well as create a need for extra protection circuitry. Excellent ripple rejection is presently achieved
without this added capacitor.

:2l

Due to the relatively low gain of the MOS output stage, output voltage drop·out may occur under large load transient
conditions. Addition of an output bypass capacitor will greatly enhance load transient response as well as prevent
drop-out. For most applications it is recommended that an output bypass capacitor be used with a minimum value of:

r:::

= 15NO

Larger values will provide proportionally better transient response characteristics.
Protection circu itry

II

The TL783 regulator includes built-in protection circuitry capable of guarding the device against most overload con·
ditions encountered in normal operation. These protective features are current limiting, safe-operating-area protection,
and thermal shutdown. These circuits are meant to protect the device under occasional fault conditions only. Continuous operation in the current limit or thermal shutdown mode is not recommended.
The internal protection circuits of the TL783 will protect the device up to maximum rated VI as long as certain precautions are taken. If VI is instantaneously switched on, transients exceeding maximum input ratings may occur, which
can destroy the regulator. These are usually caused by lead inductance and bypass capacitors causing a ringing voltage
on the input. In addition, if rise times in excess of 10 VIns are applied to the input, a parasitic n-p-n transistor in parallel
with the DMOS output can be turned on causing the device to fail. If the device is operated over 50 volts and the input
is switched on rather than ramped on, a low-Q capacitor, such as a tantalum or electrolytic should be used rather than
ceramic, paper, or plastic bypass capacitors. A dissipation factor of 0.015 or greater will usually provide adequate
damping to suppress ringing. Normally, no problems will occur if the input voltage is allowed to ramp upward through
the action of an ac line rectifier and filter network.

TYPE TL783C
HIGH·VOLTAGE ADJUSTABLE REGULATOR
Similarly, if an instantaneous short circuit is applied to the outputs, both ringing and excessive ·fall times can result. A
tantalum or electrolytic bypass capacitor is recommended to eliminate this problem. However, if a large output capacitor
is used and the input is shorted, addition of a protection <;iiode may be necessary to prevent capacitor discharge through
the regulator. The amount of discharge current delivered is dependent on output voltage, size of capacitor, and fall
time of VI. A protective diode (see Figure 17) is required only for capacitance values greater than

Care should always be taken to prevent insertion of regulators into a socket with power on. Power should be turned off
before removing or inserting regulators.

Load regulation

The current set resistor (R1) should be located close to the regulator output terminal rather than near the load. This
eliminates long line drops from being amplified through the action of R1 and R2 to degrade load regulation. To provide
remote ground sensing, R2 should be near the load ground.

description
The TL 1451 incorporates on a single monolithic chip all the functions required in the construction of two pulse-widthmodulation control circuits, Designed primarily for power supply control, the TL 1451 contains an on-chip 2.5-volt
regulator, two error amplifiers, an adjustable oscillator, two dead-time comparators, under-voltage lockout circuitry,
and dual common-emitter output transistor circuits.
The uncommitted output transistors provide common-emitter output capability for each controller. The internal amplifiers
exhibit a common-mode voltage range from 0,4 volts to 1,5 volts. The dead-time control comparator has no offset
unless externally altered and may be used to provide 0% to 100% dead time, The on-chip oscillator may be operated
by terminating RT (pin 2) and CT (pin 1). During low VCC conditions, the under-voltage lockout control circuit feature
locks the outputs off until the internal circuitry is operational.
The TL1451 is characterized for operation from -20°C to 85°C,

description
The TL 1525A/TL1527A series of pUlse-width modulation integrated circuits are designed to offer improved performance
and lower external parts count when used to implement various types of switching power supplies. Each device includes
an on-chip 5.1-volt reference. error amplifier. programmable oscillator, pulse-steering flip-flop. a latched comparator
under-voltage lockout, shutdown circuitry, and complementary source or sink outputs. The on-chip 5.1-volt reference
is trimmed to ± 1 % initial accuracy, serves as a reference output. and supplies the internal regulator control circuitry.
The input common-mode range of the error amplifier includes the reference voltage. which eliminates the need for
external divider resistors.
The oscillator operates at a fixed frequency determined by one timing resistor RT and one timing capacitor CT. The
timing resistor establishes the constant charging current for CT. resulting in a linear voltage ramp at CT, which is
fed to the PWM comparator providing linear control of the output pulse duration by the error amplifier. A Sync input
to the oscillator allows for external synchronization or for multiple units to be slaved together. A single external resistor
between the CT pin and the Discharge pin provides a wide range of dead-time adjustment. These devices also feature
built-in soft-start circuitry that requires only an external timing capacitor. The Shutdown pin controls both the softstart and the output drivers. and provides instantaneous turn-off with soft-start recycle for slow turn-on. The softstart and output driver circuitry are also controlled by the under-voltage lockout circuit. which. during low-input supply
voltage of less than that required for normal operation. keeps the soft-start capacitor discharged and the output drivers
off.
Another unique feature is the S-R latch following the PWM comparator. This feature enables the output drivers to
be turned off any time the PWM pulse is terminated. The latch is reset with each clock pulse. However. the PWM
outputs will remain turned off for the duration of the period if the PWM comparator output is in a low-level state.
The TL 1525A. TL2525A, and TL3525A output stages feature NOR logic resulting in a low output for an off-state.
The TL1527A. TL2527A. and.TL3527A output stages feature OR logic resulting in a high-level output for an offstate. The output stages are totem-pole designs capable of sourcing or sinking 200 milliamperes of output current.

F/F

shutdown options
1.

Use an external transistor or open-collector comparator to pull down on the Compensation terminal (Pin 9). This
will set the PWM latch and turn off both driver outputs, If the shutdown signal is momentary, pulse-by-pulse protection
will be accomplished as the PWM latch is reset with each clock pulse.

2.

The same results may be accomplished by pulling down on the Soft-Start terminal (Pin 8) with the only difference
being that on this pin shutdown will not affect the amplifier compensation network, but must discharge any softstart capacitance.

3.

Application of a positive-going signal to the Shutdown terminal (Pin 10) will provide the most rapid shutdown of
the driver outputs but will not immediately set the PWM latch if there is a capacitor at the Soft-Start terminal. The
capacitor will discharge but at a current twice the charging current. The PWM latch can be set on a pulse-by-pulse
basis by the shutdown terminal if there is no external capacitance on the Soft-start terminal (Pin a). Slow turn-on
may still be accomplished by connecting an external capacitor, blocking diode, and charging resistor to the
Compensation terminal (Pin 9).

description
The TL7702A series are monolithic integrated circuit supply voltage supervisors specifically designed for
use as reset controllers in microcomputer and microprocessor systems. During power-up the device tests
the supply voltage and keeps the RESET and RESET outputs active (high and low, respectively) as long
as the supply voltage has not reached its nominal voltage value. Taking RESIN low has the same effect.
To ensure that the microcomputer system has reset, the TL7702A then initiates an internal time delay
that delays the return of the reset outputs to their inactive states. Since the time delay for most
microcomputers and microprocessors is in the order of several machine cycles, the device internal time
delay is determined by an external capacitor connected to the CT input (pin 3).
td = 1.3- x 104 x CT
Where: CT is in farads (F) and td is in seconds(s)

In

...o
~

In addition, when the supply voltage drops below the nominal value, the outputs will be active until the
supply voltage returns to the nominal value. An external capacitor (typically 0.1 /LF) must be connected
to the REF output (pin 1) to reduce the influence of fast transients in the supply voltage.
The TL7702AI series is characterized for operation from -25°C to 85°C; the TL7702AC series is
characterized from OOC to 70 o C.

(TOP VIEW)

This series of fixed-voltage monolithic integrated·
circuit voltage regulators is designed for a wide range
of applications. These applications include on-<:ard
regulation for elimination of noise and distribution
problems associated with single-point regulation. Each
of these regulators can deliver up to 1.5 amperes of
output current. The internal current limiting and
thermal shutdown features of these regulators make
them essentially immune to overload. In addition to
use as fixed-voltage regulators. these devices can be
used with external components to obtain adjustable
output voltages and currents and also as the powerpass element in precision regulators.

THE COMMON TERMINAL IS IN
ELECTRICAL CONTACT WITH
THE MOUNTING 8ASE

NOTE 1: For operation above 25°C free-air or case temperature, refer to Figures 1 and 2. To avoid exceeding the design maximum virtual junction temperature,
these ratings should not be exceeded. Due to variations in individual device electrical characteristic"S and thermal resistance, the built-in thermal overload
protection may be activated at power levels slightly above or below the rated dissipation.

JG

This series of fixed-voltage monolithic integratedcircuit voltage regulators is designed for a wide range
of applications. These applications include on-card
regulation for elimination of noise and distribution
problems associated with single-point regulation. In
addition, they can be used with power-pass elements
to make high-current voltage regulators. One of these
regulators can deliver up to 100 mA of output current.
The internal current limiting and thermal shutdown
features of these regulators make them essentially
immune to overload. When used as a replacement for
a Zener-diode-resistor combination, an effective
improvement in output impedance of typically two
orders of magnitude can be obtained together with
lower-bias current.

For operation aboye 25°C free-air temperature, refer to Figures 1 and 2. To avoid exceeding the design maximum virtual junction temperature,
these ratings should not be exceeded. Due to variations in individual device electrical characteristics and thermal resistance, the built-in thermal
overload protection may be activated at power levels slightly above o~ below the rated dissipation.

description

140

This series of fixed-voltage monolithic integratedcircuit voltage regulators is designed for a wide range
of applications, These applications include on-card
regulation for elimination of noise and distribution
problems associated with single-point regulation. Each
of these regulators can deliver up to 500 milliamperes
of output current. The internal current limiting and
thermal shutdown features of these regulators make
them essentially immune to overload. In addition to
use as fixed-voltage regulators. these devices can be
used with external components to obtain adjustable
output voltages and currents and also as the power
pass element in precision regulators.

KCPACKAGE

This series of fixed-negative-voltage monolithic
integrated-circuit voltage regulators is designed to
complement Series uA7800 in a wide range of
applications. These applications include on-card regulation for elimination of noise and distribution
problems associated with single-point regulation, Each
of these regulators can deliver up to 1.5 amperes of
output current. The internal current limiting and
thermal shutdown features of these regulators make
them essentially immune to overload, I n addition to
use as fixed-voltage regulators, these devices can be
used with external components to obtain adiustable
output voltages and currents and also as the power
pass element in precision regulators.

COMMON

This series of fixed-negative-voltage monolithic
integrated-circuit voltage regulators is designed to
complement Series uA78MOO in a wide range of
applications. These applications include on-card regulation for elimination of noise and distribution
problems associated with single-point regulation. Each
of these regulators can deliver up to 500 milliamperes
of output current. The internal current limiting and
thermal shutdown features of these regulators make
them essentially immune to overload. In addition to
use as fixed-voltage regulators, these devices can be
used with external components to obtain adjustable
output voltages and currents and also as the power
pass element in precision regulators.

description

Q)

The UC3846 and UC3847 pulse-width-modulation controller integrated circuits are designed to offer
improved performance and lower external parts count in fixed-frequency current-mode control systems.
These devices provide improved line regulation, enhanced load response characteristics, and a simpler,
easer-to-design control loop. Other advantages include inherent pulse-by-pulse current-limiting capability,
automatic symmetry correction for push-pull converters, and the ability to parallel power modules while
maintaining equal current sharing.

a:

Q)

C)

CO

~

'0

>

Protection circuitry includes a latched comparator under-voltage lockout, programmable current limiting,
and self-start capability. A shutdown function is also available; this can either initiate a complete shutdown
with automatic restart, or latch the supply off.
Other features include fully latched operation, double-pulse suppression, deadtime adjust capability, and
a ± 1 % trimmed bandgap reference.

description
The ADC0801, ADC0802, ADC0803, and ADC0805 are CMOS 8-bit successive-approximation analogto-digital converters that use a modified potentiometric (256R) ladder, These devices are designed to operate
from common microprocessor control buses, with the three-state output latches driving the data bus, The
devices can be made to appear to the microprocessor as a memory location or an I/O port,
A differential analog voltage input allows increased common-mode rejection and offset of the zero-input
analog voltage value, Although a reference input (REF/2) is available to allow 8-bit conversion over smaller
analog voltage spans or to make use of an external reference, ratiometric conversion is possible with the
REF/2 input open, Without an external reference, the conversion takes place over a span from VCC to
analog ground (ANLG GND), The devices can operate with an external clock Signal or, with an additional
resistor and capacitor, can operate using an on-chip clock generator.
The ADC08011, ADC08021, ADC08031, and ADC08051 will be characterized for operation from -40°C
to 85°C,

description
The ADC0804C is a CMOS 8-bit successive-approximation analog-to-digital converter that uses a modified
potentiometric (256R) ladder. The ADC0804 is designed to operate from common microprocessor control
buses, with the three-state output latches driving the data bus. The ADC0804 can be made to appear
to the microprocessor as a memory location or im 1/0 port.
A differential analog voltage input allows increased common-mode rejection and offset of the zero-input
analog voltage value. Although a reference input (REF/2) is available to allow 8-bit conversion over smaller
analog voltage spans or to make use of an external reference, ratiometric conversion is possible with the
REF/2 input open. Without an external reference, the conversion takes place over a span from VCC to
analog ground (ANLG GND). The ADC0804 can operate with an external clock signal or, with an additional
resistor and capacitor, can operate using an on-chip clock generator.
The ADC0804C is characterized for operation from ooC to 70 oC.

TYPE ADC0804C
8·BIT ANALOG·TO·DIGITAL CONVERTER
WITH DIFFERENTIAL INPUTS
PRINCIPLES OF OPERATION
The ADC0804 contains a circuit equivalent to a 256-resistor network. Analog switches are sequenced
by successive approximation logic to match an analog differential input voltage (Vin + - Vin _) to a
corresponding tap on the 256-resistor network. The most-significant bit (MSB) is tested first. After eight
comparisons (64 clock periods), an eight-bit binary code (1111 1111 = full scale) is transferred to an
output latch and the interrupt (lNTR) output goes low. The device can be operated in a free-running mode
by connecting the INTR output to the write (WR) input and holding the conversion start (CS) input at a
low level. To ensure start-up under all conditions, a low-level WR input is required during the power-up
cycle. Taking CS low anytime after that will interrupt a conversion in process.
When the WR input goes low, the ADC0804 successive approximation register (SAR) and eight-bit shift
register are reset. As long as both CS and WR remain low, the ADC0804C will remain in a reset state.
One to eight clock periods after CS or WR makes a low-to-high transition, conversion starts.
When the CS and WR inputs are low, the start flip-flop is set and the interrupt flip-flop and eight-bit register
are reset. The next clock pulse transfers a logic high to the output of the start flip-flop. The logic high
is ANDed with the next clock pulse placing a.logic high on the reset input of the start flip-flop. If either
CS or WR have gone high, the set signal to the start flip-flop is removed causing it to be reset. A logic
high is placed on the D input of the eight-bit shift register and the conversion process is started. If the
CS and WR inputs are still low, the start flip-flop, the eight-bit shift register, and the SAR remain reset.
This action allows for wide CS and WR inputs with conversion starting from one to eight clock periods
after one of the inputs goes high.
When the logic high input has been clocked through the eight-bit shift register, completing the SAR'search,
it is applied to an AND gate controlling the output latches and to the D input of a flip-flop. On the next
clock pulse, the digital word is transferred to the three-state output latches and the interrupt flip-flop is
set. The output of the interrupt flip-flop is inverted to provide an INTR output that is high during conversion.
and low when the conversion is completed.
When a low is at both the CS and RD inputs, an output is applied to the DBO through DB7 outputs and
the interrupt flip-flop is reset. When either the CS or RD inputs return to a high state, the DBO through
DB7 outputs are disabled (returned to the high-impedance state). The interrupt flip-flop remains reset.

The ADC0808 and ADC0809 are monolithic CMOS devices with an 8-channel multiplexer, an 8-bit analog-to-digital
(AID) converter, and microprocessor-compatible control logic. The 8-channel multiplexer can be controlled by a
microprocessor through a 3-bit address decoder with address load to select anyone of eight single-ended analog switches
connected directly to the comparator. The 8-bit AID converter uses the successive-approximation conversion technique
featuring a high-impedance threshold detector, a switched-capacitor array, a sample-and-hold, and a successiveapproximation register (SAR).
The comparison and converting methods used eliminate the possibility of missing codes, nonmonotonicity, and the
need for zero or full-scale adjustment. Also featured are latched 3-state outputs from the SAR and latched inputs to
the multiplexer address decoder. The single 5-volt supply and low power requirements make the ADC0808 and
ADC0809 especially useful for a wide variety of applications. Ratiometric. conversion is made possible by access to
the reference voltage input terminals.

TYPES ADC0808. ADC0809
CMOS ANALOG·TO·DlGITAL CONVERTERS
WITH 8·CHANNEL MULTIPLEXERS
The AOC0808 and AOC0809 each consists of an analog signal multiplexer, an 8-bit successive-approximation converter,
and related control and output circuitry.

multiplexer
The analog mutiplexer selects 1 of 8 single-ended input channels as determined by the address decoder. Address
load control loads the address code into the decoder on a low-to-high transition.

converter
The CMOS threshold detector in the successive-approximation conversion system determines each bit by examining
the charge on a series of binary-weighted capacitors (Figure 1). In the first phase of the conversion process, the analog
input is sampled by closing switch Sc and all ST switches, and by simultaneously charging all the capacitors to the
input voltage.
In the next phase of the conversion process, all ST and Sc switches are opened and the threshold detector begins
identifying bits by identifying the charge (voltage) on each capacitor relative to the reference voltage. In the switching
sequence, all eight capacitors are examined separately until all 8 bits are identified, and then the charge-convert sequence
is repeated. In the first step of the conversion phase, the threshold detector looks at the first capacitor (weight ~ 128).
Node 128 of this capacitor is switched to the reference voltage, and the equivalent nodes of all the other capacitors
on the ladder are switched to REF - . If the voltage at the summing node is greater than the trip-point of the threshold
detector (approximately one-halfthe VCC voltage). a bit is placed in the output register, and the 128-weight capacitor
is switched to REF -. If the voltage at the summing node is less than the trip point of the threshold detector, this
128-weight capacitor remains connected to REF + through the remainder of the capacitor-sampling (bit-counting)
process. The process is repeated for the 64-weight capacitor, the 32-weight capacitor, and so forth down the line,
until all bits are counted.
With each step of the capacitor-sampling process, the initial charge is redistributed among the capacitors. The conversion
process is successive approximation, but relies on charge redistribution rather than a successive-approximation register
(and reference 01 AI to count and weigh the bits from MSB to LSB.

NOTES: 4. For IN - more positive than IN +, the digital output code will be 0000 0000. Connected to each analog input are two·on·chip diodes that will
conduct forward current for analog input voltages one diode drop below ground or one diode drop above Vee. Care must be taken during testing
at low Vec levels (4.5 V) because high·level analog input (5 VI can, especially at high temperatures, cause this input diode to conduct and cause
errors for analog inputs that are near full~scale. As long as the analog Input voltage does not exceed the supply voltage by more than 50 mV,
the output code will be correct. To achieve an absolute O-V to 5-V input voltage range requires a minimum Vce of 4.950 volts for all variations
of temperature and load.
5. An internal zener diode is connected from the Vee input to ground and from V+ to ground. The breakdown voltage of each diode is approximately
7 V. The V + diode is a shunt regulator and connects to Vce via a diode. When the voltage regulator powers the converter, this diode ensures
that the Vee input is less than the zener breakdown voltage (6.4 VI. A series resistor is recommended to limit the maximum current into the V+ input.

PRINCIPLES OF OPERATION
The ADC0831, ADC0832, ADC0834, and ADC0838 use a sample data comparator structure that converts
differential analog inputs by a successive-approximation routine. The input voltage to be converted is applied
to a channel terminal and is compared to ground (single-ended)' to an adjacent channel (differential), or
to a common terminal (pseudo-differential) that can be an arbitrary voltage. The input terminals are assigned
a positive ( +) or negative ( -) polarity. If the signal input applied to the assigned positive terminal is less
than the signal on the negative terminal, the converter output is all zeroes.
Channel selection and input configuration are under software control using a serial data link from the
controlling processor. A serial communication format allows more functions to be included in a converter
package with no increase in size. In addition, it eliminates the transmission of low-level analog signals
by locating the converter at the analog sensor. This process returns noise-free digital data to the processor.
A particular input configuration is assigned during the multiplexer addressing sequence. The multiplexer
address is shifted into the converter through the data input (01) line. The ADC0831 contains only one
differential input ctlannel having a fixed polarity assignment and not requiring addressing. The multiplexer
address selects the analog inputs to be enabled and determines whether the input is single-ended or
differential. When the input is differential, the polarity of the channel input is assigned. Differential inputs
are assigned to adjacent channel pairs. For example, channel 0 and channel 1 may be selected as a
differential pair. These channels can not act differentially with any other channel. In addition to selecting
the differential mode, the polarity may also be selected. Either channel of the channel pair may be designated
as negative or positive.

The common input on the ADC0838 can be used for a pseudo-differential input. In this mode, the voltage
on the input is negative to any other channel. This voltage can be any reference potential common to all
channel inputs. This feature is useful in single-supply applications where all analog circuits are biased to
a potential other than ground.
Operation of the ADC0831, ADC0832, ADC0834, and ADC0838 is similar with the exception of multiplexer
addressing. The ADC0838 has all the features of the other converts and is used for the functional block
diagram.
A conversion is initiated by setting the chip select (CS) input low. This enables all logic circuits. The CS
input must be held low for the complete conversion process. A clock input is received from the processor.
On each low-to-high transition of the clock input, the data on the 01 input is clocked into the multiplexer
address shift register. The first logic high on the input is the start bit. A 2- to 4-bit assignment word follows
the start bit. On each successive low-to-high transition of the clock input, the start bit and assignment
word are shifted through the shift register. When the start bit has been shifted into the start location of
the multiplexer register, the input channel has been selected and conversion starts. The SAR status output
(SARS) goes high to indicate that a conversion is in progress and the 01 input to the multiplexer shift register
is disabled for the duration of the conversion.

2-, 4-, 8-CHANNEL AID PERIPHERALS WITH
SERIAL CONTROL AND MULTIPLEXER OPTIONS
An interval of one clock period is automatically inserted to allow for the selected multiplexer channel to
settle. The data output DO comes out of the high-impedance state and provides a leading low for this
one clock period of multiplexer settling time. The SAR comparator compares successive outputs from the
resistive ladder with the incoming analog signal. The comparator output indicates whether the analog input
is greater than or less than resistive ladder output. This data is parallel loaded into a 9-bit shift register
which immediately outputs an 8-bit serial data word. This output is sent to the DO output with the mostsignificant bit (MSB) first. After eight clock periods the conversion is complete and the SAR status (SARS)
output goes low. When CS goes high, all internal registers are cleared. At this time the output circuits
go to three-state. If another conversion is desired, the CS line must make a high-to-Iow transition followed
by address information.
In the ADC0831, only the MSB data is output first. The ADC0832 and ADC0834 output the LSB data
first after the MSB first data stream is output. In the ADC0838, the programmer has the option of selecting
MSB first or LSB first. To output LSB first, the shift enable (SE) control input must go low. Data stored
in the 9-bit shift register is now output with LSB first. The ADC0831 data is only output in MSB-first format.
The DI and DO pins can be tied together and controlled by a bi-directional processor I/O bit received on
a single wire. This is possible because the DI input is only examined during the multiplexer addressing
interval and the DO output is still in a high-impedance state.

placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.

The TL500C and TL501 C analog processors and TL502C and TL503C digital processors provide the basic functions for
a dual-slope-integrating analog-to-digital converter.
The TL500C and TL501C contain the necessary analog switches and decoding circuits, reference voltage generator,
buffer, integrator, and comparator. These devices may be controlled by the TL502C, TL503C, by discrete logic, or by a
software routine in a microprocessor.

The BCD counter in the digital processor (see Figure 2) and the control logic divide each measurement cycle into three
phases. The BCD counter changes at a rate equal to one-half the oscillator frequency.

auto-zero phase
The cycle begins at the end of the integrate-reference phase when the digital processor applies low levels to inputs A
and B of the analog processor. If the trigger input is at a high level, a free-running condition exists and continuous
conversions are made. However, if the trigger input is low, the digital processor stops the counter at 20,000, entering a
hold mode. In this mode, the processor samples the trigger input every 4000 oscillator pulses until a high level is detected.
When this occurs, the counter is started again and is carried to completion at 30,000. The reference voltage is stored on
reference capacitor Cref, comparator offset voltage is stored on integration capacitor CX, and the sum of the buffer and
integrator offset voltages is stored on zero capacitor CZ. During the auto-zero phase, the comparator output is
characterized by an oscillation (limit cycle) of indeterminate waveform and frequency that is filtered and d-c shifted by
the level sh ifter.

integrate-input phase
The auto-zero phase is ,completed at a BCD count of 30,000, and high levels are applied to both control inputs to
initiate the integrate-input phase. The integrator charges Cx for a fixed time of 10,000 BCD counts at a rate determined
by the input voltage. Note that during this phase, the analog inputs see only the high impedance of the non inverting
operational amplifier input. Therefore, the integrator responds only to the difference between the analog input terminals,
thus providing true differential inputs.

integrate-reference phase
At a BCD count of 39,999 + 1 = 40,000 or 0, the integrate-input phase is terminated and the integrate-reference phase
is begun by sampling the comparator output_ If the comparator output is low corresponding to a negative average
analog input voltage, the digital processor applies a low and a high to inputs A and B, respectively, to apply the
reference voltage stored on Cref to the buffer. If the comparator output is high corresponding to a positive input,
inputs A and B are made high and low, respectively, and the negative of the stored reference voltage is applied to the
buffer_ In either case, the processor automatically selects the proper logic state to cause the integrator to ramp back
toward zero at a rate proportional to the reference voltage_ The time required to return to zero is measured by the
counter in the digital processor_ The phase is terminated when the integrator output crosses zero and the counter
contents are transferred to the register, or when the BCD counter reaches 20,000 and the over-range indication is
activated_ When activated, the over-range indication blands all but the most significant digit and sign_
Seventeen parallel bits (4-1/2 digits) of information are strobed into the buffer register at the end of the integration
phase_ Information for each digit is multiplexed out to the BCD outputs (TL503C) or the seven-segment drivers
(TL502C) at a rate equal to the oscillator frequency divided by 400_

description
The TL505C is an analog-to-digital converter building block designed for use with TMS 1000 type microprocessors. It
contains the analog elements (operational amplifier, comparator, voltage reference, analog switches, and switch drivers)
necessary for a unipolar automatic-zeroing dual-slope converter. The logic for the dual·slope conversion can be
performed by the associated MPU as a software routine or it can be implemented with other components such as the
TL502 logic-control device.
The high-impedance MOS inputs permit the use of less expensive, lower value capacitors for the integration and offset
capacitors and permit conversion speeds from 20 per second to 0.05 per second.
The TL505C is a product of TI's BI-MOS process, which incorporates bipolar and MOSFET transistors on the same
monolithic integrated circuit. The TL505C is characterized for operation from DoC to 70°C.

description
The Tl507 is a low-cost single-slope analog-to-digital
converter designed to convert analog input voltages
between 0.25 VCC1 and 0.75 VCC1 into a pulsewidth-modulated output code. It contains a 7-bit
synchronous counter, a binary-weighted resistor
ladder network, an operational amplifier, two
comparators, a buffer amplifier, an internal regulator,
and necessary logic circuitry. Integrated-injection logic
(l 2 l) technology makes it possible to offer this
complex circuit at low cost in a small dual-in-line B-pin
package.

A high level on the reset pin clears the counter to zero, which sets the internal
ramp to 0.75 Vee- Internal pull·down resistors keep the reset and enable
pins low when not connected.

In continuous operation, it is possible to obtain conversion speeds up to 1000 per second. The Tl507 requires external
signals for clock, reset, and enable. Versatility and simplicity of operation coupled with low cost, makes this converter
especially useful for a wide variety of applications.
The Tl507C is characterized for operation from 0 DC to 70 DC, and the Tl5071 is characterized for operation from
_40DC to B5 DC.

PRINCIPLES OF OPERATION
The TL507 is a single-slope analog-to-digital converter. All single-slope converters are basically voltage-time or currentto-time converters. A study of the functional block diagram shows the versatility of the TL507.
An external clock signal is applied through a buffer to a negative-edge-triggered synchronous counter. Binary-weighted
resistors from the counter are connected to an operational amplifier used as an adder. The operational amplifier generates
a signal that ramps from 0.75, VCCl down to 0.25, VCC1. Comparator 1 compares the ramp signal to the analog
input signal. Comparator 2 functions as a fault defector. With the analog input voltage in the range 0.25 • VCC1
to 0.75 ' VCC1, the duty cycle of the output signal is determined by the unknown analog input as shown in Figure 2
and the Function Table.

description
The TL520. TL521. and TL522 are monolithic CMOS devices each with an 8-channel multiplexer, and 8-bit analog-todigital (AID) converter, and microprocessor-compatible control logic. The 8-channel multiplexer can be controlled by
a microprocessor through a 3-bit address decoder with address load to select anyone of eight single-ended analog
switches connected directly to a comparator. The 8-bit AID converter uses a binary-weighted capacitor array to
implement the high-speed, successive-approximation conversion technique.

c

o

"';::;

"(i)

The comparison and conversion methods used eliminate the possibility of missing codes, nonmonotonicity, and the
need for zero or full-scale adjustment. Also featured are latched 3-state outputs and latched inputs to the multiplexer
address decoder. The single 5-volt supply and low power requirements make the TL520 and TL521 especially useful
for a wide variety of applications. The 3-volt and low power requirements make the TL522 especially useful for battery
and LCD applications. Ratiometric conversion is made possible by access to the reference voltage input terminals.

description
The TL530 and TL531 are monolithic CMOS
peripheral integrated circuits each designed to
interface a microprocessor for analog data
acquisition. These devices are complete
peripheral data acquisition systems on a single
chip and can convert analog signals to digital
data from up to 15 external analog terminals.
Each device features operation from a single
5-volt supply and additional digital input/output
capabilities. Each contains a 16-channel analog
multiplexer, an 8-bit ratiometric analog-to-digital
(A/D) converter, three 16-bit registers, and
microprocessor-compatible control logic
circuitry. Additional features include a built-in
self-test, six mUltipurpose (analog or digital)
inputs, nine external analog inputs, and an 8-pin
input/output (I/O) data port, The three on-chip
data registers store the control data, the
conversion results, and the input digital data that
can be accesssed via the microprocessor data
bus in two 8-bit bytes (most-significant byte
first). In this manner, a microprocessor can
access up to 15 external analog inputs or 6
digital signals and the positive reference voltage
that may be used ·for self-test.

description (continued)
The A/D conversion uses the successive-approximation technique employing a high-impedance chopperstabilized comparator, a 256R end-compensated voltage divider with analog switch tree, and a successiveapproximation register (SAR). This method eliminates the possibility of missing codes, nonmonotonicity,
and a need for zero or full-scale adjustment. Positive and negative reference voltage inputs make possible
ratiometric conversion and reference isolation from supply noises.
The TL5301 and TL5311 are characterized for operation from -40°C to 85°C.

functional description
The TL530 and TL531 provide direct interface to a microprocessor-based system. Control of the TL530
and TL531 is handled via the 8-line TTL-compatible 3-state data bus, the three control inputs (Read/Write,
Register Select, and Chip Select), and the Clock input. Each device contains three 16-bit internal registers.
These registers are the control register, the analog conversion data register, and the digital data register.
A high level at the Read/Write input and a low level at the Chip Select input set the device to output data
on the 8-line data .bus for the processor to read. A low level at the Read/Write input and a low level at
the Chip Select input set the device to receive instructions into the internal control register on the 8-line
data bus from the processor. When the device is in the read mode and the Register Select input is low,
the processor will read the the data contained in the analog conversion data register. However, when the
Register Select input is high, the processor reads the data contained in the digital data register.
The control register is a write-only register into which the microprocessor writes command instructions
for the device to start AID conversion and to select the analog channel to be converted, to select the output
logic levels and the direction (input or output) of the 3-bit digital I/O port, and to set interrUpt enable for
the Interrupt Request output. The analog conversion data register is a read-only register that contains the
current converter status and most recent conversion results. The digital data register is also a read-only
register that holds the 3-bit I/O port status and digital input logic levels from the six multipurpose and the
three digital inputs.

Internally each device contains a byte pointer that selects the appropriate byte during two cycles of the
Clock input in a normal 16-bit microprocessor instruction. The internal pointer will automatically point to
the most-significant (MS) byte after the first complete clock cycle any time that the Chip Select is at the
high level for at least one clock cycle. This causes the device to treat the next Signal on the 8-line data
bus as the MS byte. A low level at the Chip Select input activates the inputs and outputs and an internal
function decoder. However, no data is transferred until the Clock goes high. The internal byte pointer first
points to the MS byte of the selected register during the first clock cycle. After the first clock cycle in
which the MS byte is accessed, the internal pointer switches to the LS byte and remains there for as long
as Chip Select is low. The MS byte of any register may be accessed by either an 8-bit or a 16-bit
microprocessor instruction; however, the LS byte may only be accessed by a 16-bit microprocessor
instruction.
Normally, a two-byte word is written into or read from the controlling processor, but a single byte can
be read by the processor by proper manipulation of the Chip Select input. This can be used to read conversion
status from the analog conversion data register or the digital multipurpose input levels from the digital
data register. The format and content of each two-byte word is shown in Figures 1 through 3.
A conversion cycle is started after a two-byte instruction is written into the control register and the start
conversion (SC) bit is a logiC high. This two-byte instruction also selects the input analog channel, configures
the 3-bit digital I/O pins, and sets the interrupt enable bit. The status (EOC) bit in the analog conversion
data register is reset and remains reset until the conversion is completed, at that time the status bit is
then set again. After conversion, the results are loaded into the analog conversion data register. These
results remain in the analog conversion data register until the next conversion cylce is completed. If the
interrupt enable bit is set to a logic high level in the control register, the Interrupt Request (IRQ) output

will go low after the next conversion cycle is completed. If a new conversion command is entered into
the control register while the conversion cycle is in progress, the on-going conversion will be aborted and
a new channel acquisition cycle will immediately begin.
The Reset input allows the device to be externally forced to a known state. When a low level is applied
to the Reset input for a minimum of three clock periods, the start conversion, interrupt enable, and the
I/O port data direction bits of the control register are cleared. The A/D converter is then idled and all the
outputs including the 3-bit I/O digital port are placed in the high-impedance off-state. However, the content
of the analog conversion data register is not affected by the Reset input going to a low level.

Interrupt Enable UE)- The interrupt enable bit. when set to a logical 1 (high level), allows the IRQ pin to be activated at the completion of the next an810g-todigital conversion.
Unused Bits (X) - The MS byte bits 2 -1 through 2 - 7 and LS byte bits 2 - 1 through 2 -4 of the control register are not used internally.

Start Conversion (SC)- When the SC bit in the MS byte is set to a logical 1 (high levell, analog-ta-digital conversion on the specified analog channel will
begin immediately after the completion of the control register write.
"0 Port Data Direction (DO) - The MSB of the LS byte is the data direction bit for the 3-bit I/O port. A logical 1 configures the port as the output while a
logical 0 configures the port as an input.
Digital 1/0 Output {II0D1-IIOD3}- When the microcompressor configures the 3-bit 110 port as an output, these are the bit locations into which the output
states are written. A logical 1 written by the microprocesssor will cause the output to be high, while a logical 0 wlll cause the output to be low.
Analog MUltiplex Address lAO-A31- These four address bits are decoded by the analog multiplexer and used to select the appropriate analog channel as

16·BIT READ
AID Status (EOC)- The AID status-end-of-converesion (EOC) bit is set whenever an analog-to-digital conversion is successfully completed by the AID converter.
The status bit is cleared by a 16-bit write from the microprocessor to the control register. The remainder of the bits in the MS byte of the analog conversion
data are always reset to logical 0 to simpltfy microprocessor interrogation of the AID converter status.
AID Result (RO-R71- The LS byte of the analog conversion data register contains the result of the analog-to-digital conversion. Result bit R7 is the MSB and
the converter follows the standard convention of assigning a code of all ones (11111111) to a full-scale analog voltage. There are no special overflow or
underflow indications.

A conversion cycle is started after a two-byte instruction is written into the control register and the start
conversion (SC) bit is a logic high. This two-byte instruction also selects the input analog channel to be
converted. The status (EOC) bit in the analog conversion data register is reset and remains reset until the
conversion is completed. at that time the status bit is then set again. After conversion. the results are
loaded into the analog conversion data register. These results remain in the analog conversion data register
until the next conversion cylce is completed. If a new conversion command is entered into the control
register while the conversion cycle is in progress. the on-going conversion will be aborted and a new channel
acquisition cycle will immediately begin.
The Reset input allows the device to be externally forced to a known state. When a low level is applied
to the Reset input for a minimum of three clock periods. the start conversion bit of the control register
is cleared. The A/D converter is then idled and all the outputs are placed in the high-impedance off-state.
However. the content of the analog conversion data register is not affected by the Reset input going to
a low level.

description
The TL601, TL604, TL607, and TL610 are a family
of monolithic P-MOS analog switches that provide
fast switching speeds with high rofflron ratio and no
offset voltage. The p-channel enhancement-type MOS
switches will accept analog signals up to ±10 volts and
are controlled by TTL-compatible logic inputs. The
monolithic structure is made possible by BI-MOS
technology, which combines p-channel MOS with
standard bipolar transistors.
These switches are particularly suited for use in
military, industrial, and commercial applications such
as data acquisition, multiplexers, A/O and D/A
converters, MODEMS, sample-and-hold systems, signal multiplexing, integrators, programmable operational ampl.ifiers, programmable voltage regulators,
crosspoint switching networks, logic interface, and
many other analog systems.
The TL601 is an SPDT switch with two logic control
inputs. The TL604 is a dual complementary SPST
switch with a single control input. The TL607 is an
SPDT switch with one logic control input and one
enable input. The TL610 is an SPST switch with
three logic control inputs. The TL610 features a
higher rofflron ratio than the other members of the
family.

Figure 1 shows power supply boundary conditions for proper operation of the TL601 Series. The range of operation
for supply Vee + from + 5 V to + 25 V is shown on the vertical axis. The range of Vee _ from - 5 volts to - 25 volts
is shown on the horizontal axis. A recommended 30-volt maximum voltage differential from Vee + to Vee _ governs
the maximum Vee + for a chosen Vee _ (or vice versa). A minimum recommended difference of 15 volts from Vee +
to Vee _ and the boundaries shown in Figure 1 allow the designer to select the proper combinations of the two supplies.
The designer-selected Vee + for a chosen Vee _ supply values limit th'e maximum input voltage that can be applied to
either switch terminal; that is, the input voltage should be between Vee _ + 8 V and Vee + to keep the on-state
resistance within specified limits.

AID Status (EOCI- The AID status end-af-conversion (EOe) bit is set whenever an analog-ta-digital conversion is successfully completed by the AID converter.
The status bit is cleared by a l6-bit write from the microprocessor to the control register. The remainder of the bits in the MS byte of the analog conversion
data register are always reset to logicat 0 to simplify microprocessor interrogation of the A/D converter status.
AID Result (RO-R7) - The LS byte of the analog conversion data register contains the result of the analog-ta-digital conversion. Result bit R7 is the MSB and
the converter follows the standard convention of assigning a code of all ones (11111111\ to a full-scale analog voltage. There are no special overflow

NOTES: 5. Linearity error is the deviation from the best straight line through the AID transfer characteristics.
6. Zero error is the difference between the output of an ideal and an actual AID for zero input voltage; full-scale error is that same difference for
full-scale input voltage.
7. Total unadjusted error is the sum of linearity, zero, and full-scale errors.
8. Absolute accuracy error is the maximum difference between an analog value and the nominal midstep value within any step. This includes all
errors including inherent quantization error, which is the ±O.5 LSB uncertainty caused by the AID converters finite resolution.
9. If chip-select setup time, tsulCS), is less than 0.14 microseconds, the effective data output enable time, ten' may extend such that tsu(CS) + ten
is equal to a maximum of 0.475 microseconds.

o....I

The TLC540 and TLC541 are LinCMOSTM A/D
peripherals built around an 8-bit switchedcapacitor successive-approximation A/D
converter. They are designed for serial interface
to a microprocessor or peripheral via a threestate output with up to four control inputs
[including independent System Clock, I/O Clock,
Chip Select (CS), and Address Input]. A
4-megahertz system clock for the TLC540 and
a 2.1-megahertz system clock for the TLC541
with a design that includes simultaneous
read/write operation allow high-speed data
transfers and sample rates of up to 71,910
samples per second for the TLC540 and 29,144
samples per second for the TLC541 . In addition
to the high-speed converter and versatile control
logic, there is an on-chip 12-charinel analog
multiplexer that can be used to sample anyone
of 11 inputs or an internal "self-test" voltage,
and a sample-and-hold that can operate
automatically or under processor control.

NOTES: 3. Analog input voltages greater than that applied to REF + convert as all "1 "s (11111111)' while input voltages less than that applied to REFconvert as all "O"s (00000000). For proper operation, REF+ voltage must be at least 1 volt higher than REF - voltage. Also, adjusted errors
may increase as this differential reference voltage falls ,below 4.75 volts.

II

4. To minimize errors caused by noise at the Chip Select input, the internal circuitry waits for two system clock cycles (or less) after a chip select
falling edge is detected before responding to control input signals. Therefore, no attempt should be made to clock-in address data until the chip
select setup time has elapsed.
5. This;s the time required for the clock input signal to fall from VIH min to VIL max or to rise from VIL max to VIH min.

8·BIT ANALOG·TO·DlGITAL PERIPHERALS
WITH SERIAL CONTROL AND 11 INPUTS
principles of operation
The TLC540 and TLC541 are each complete data acquisition systems on a single chip. They include such
functions as analog multiplexer, sample·and·hold, 8·bit A/D converter, data and control registers, and control
logic. For flexibility and access speed, there are four control inputs [two clocks, chip select (CS). and
address]. These control inputs and a TTL-compatible 3-state output are intended for serial communications
with a microprocessor or microcomputer. With judiciOUS interface timing, with TLC540 a conversion can
be completed in 10 microseconds, while complete input-conversion-output cycles are being repeated every
14 microseconds. With TLC541 a conversion can be completed in 19 microseconds, while complete inputconversion-output cydes are repeated every 35 microseconds. Furthermore, this fast conversion can be
executed on any of 11 inputs or its built-in "self-test," and in any order desired by the controlling processor.
Though they can be operated "tied" together, the System Clock and I/O Clock are normally used
independently, with no special phase or speed relationship to be considered. This allows integrated circuit
operation to continue independent of serial Input/Output timing, permitting manipulation of the I/O Clock
as desired for a wide range of software and hardware needs.
The I/O Clock, Data Input, and Data Output are controlled by CS. It floats the 3-state output and shuts
off signals to other control inputs while it is high. This allows any pins except pin 1 5 to share lines with
other integrated circuits. A normal control sequence is as follows: (1) CS goes low; (2) a new positivelogic multiplexer address is clocked in through the address input on the first four I/O Clock rising edges
while previous conversion results are brought out on the first seven I/O Clock falling edges. Input and output
most-significant bits (MSB) are first, with the output MSB available at the start of the cycle; (3) the onchip sample-and-hold begins sampling a newly addressed input after the 4th falling edge, and goes into
the hold mode on the 8th falling I/O Clock edge just before conversion; (4) CS must then go high or the
I/O Clock must remain low for at least 40 system clock cycles to allow conversion. A new address may
then be loaded or the previous conversion results read any time CS is brought low, but it should be noted
that any pending conversion may stop.
The instant that the TLC540 or TLC541 holds a sample of the analog input, conversion can be determined
under software control (or by external logic), by keeping the 8th I/O Clock cycle high. Any output data
will have already been shifted out, and TLC540 or TLC541 will continue sampling a new analog input.
At the desired time, the I/O Clock signal can then be lowered freezing the voltage and turning off all analog
inputs. In this manner, signals can be sampled at precise intervals for a wide range of comparison or
processing applications, in much the same manner as a strobe light is used to determine engine speed.

description
The TLC549 is a LinCMOSTM AID Peripheral integrated circuit built around an 8-bit switched-capacitor
successive-approximation AID converter. It is designed for serial interface with a microprocessor or
peripheral through a 3-state data output and an analog input. The TLC549 uses only the InputlOutput Clock
(I/O Clock) input along with the Chip Select (CS) input for data control. The I/O Clock input frequency
of the TLC549 is guaranteed up to 525 kilohertz.
Operation of the TLC549 is very similar to that of the more complex TLC540 and TLC541 devices; however,
unlike the TLC540 and TLC541, the TLC549 provides an on-chip system clock that operates typically
at 4 megahertz and requires no external components. The on-chip system clock allows internal device
operation to proceed independently of serial input/output data timing, permitting manipulation of the TLC549
as desired for a wide range of software and hardware requirements. The I/O Clock together with the internal
system clock allow high-speed data transfer and sample rates of up to 29,144 cycles per second.
Additional TLC549 features include versatile control logic, an on-chip sample-and-hold circuit that can
operate automatically or under processor control, and a high-speed converter with differential highimpedance reference voltage inputs that ease ratiometric conversion, scaling, and analog circuit isolation
from logic and supply noises. Design of the totally switched-capacitor successive-approximation converter
circuit allows guaranteed low-error conversion of ± 0.5 least-significant bit (LSB) in less than
19 microseconds.
The TLC549M is characterized for operation over the full military temperature range of - 55 ac to 125 ac.
The TLC5491 is characterized for operation from - 40 ac to 85 ac.

description
The TlC7126. operating with externally connected passive elements, is a versatile high-performance low-power
3 1/2-digit dua)-slope-integrating analog-to-digital (A/D) converter. All the necessary active devices are contained
on a single LinCMOS™ integrated circuit including seven-segment decoders, display drivers, backplane driver,
reference, and clock, The device is designed to interface with a liquid-crystal display (LCD), The supply current is
100 microamperes maximum and is suited for 9-volt battery operation,
The TLC7126 is characterized by accuracy, versatility, and economy, Accuracy is obtained by an automatic
compensation for zero offset to less than 10 microvolts, a zero-reading temperature coefficient less than 1 microvolt/oC,
an input bias current of 10 picoamperes maximum, and a rollover error of less than one count. Applications include
the conversion of analog data from high-impedance sensors of pressure, temperature, light, moisture, position, and
many others, Analog-to-digital conversion logic provides display signals for weight scales, thermometers, light-level
indicators, and many other applications, By changing the passive components, an ICl7106 socket can be upgraded
to TLC7126,

PRINCIPLES OF OPERATION
The principles of operation of the TLC7126 are similar to the combined operation of the TL500C and
TL502C. The TLC7126 has an analog section similar to TL500C and a digital section similar to TL502C
(see functional block diagram). Each measurement cycle is divided into three phases. The phases are autozero. integrate input. and integrate reference.

auto-zero phase
The cycle begins at the end of the integrate-reference phase when the digital section control logic applies
a low-level signal to the analog section. This action initiates three switching operations: IN HI and IN La
signals are disconnected from the input pins and internally shorted to analog COMMON; the reference
capacitor Cref charges to the reference voltage; and a feedback loop is connected from the comparator
output to the integrator input. The feedback loop charges the auto-zero capacitor. Cz. to compensate for
offset voltages in the buffer amplifier. integrator. and comparator. Since the comparator is included in the
loop. the auto-zero accuracy is limited only by the system noise.

AID CONVERTER AND LCD DRIVER
integrate input phase
At the end of the auto-zero phase, the digital section control logic output goes high and operates the analog
section switches to open the feedback loop, removes the internal short from input to COMMON, and applies
IN HI and IN LO signals to the analog section input. The converter then integrates the differential voltage
between IN HI and IN LO for a fixed time. This differential voltage can vary within a wide common-mode
range (i.e., within a volt of either supply). The integrated signal polarity is determined at the end of this phase.

integrate reference phase
After a predetermined number of counts, the digital section operates the analog section switches to connect
IN La to analog COMMON and IN HI to the previously charged reference capacitor, Cref. Cref discharges
returning the integrator output to zero. The time required for the output to return to zero is proportional
to the differential input signal. The digital reading displayed will be 1000 VINREF.
Digital-section timing may be controlled by an external RC network, crystal, or oscillator (see Figure 4).
The clock frequency is divided by four prior to clocking the decade counters and is further divided to time
the three phases of operation (refer to Figure 1). The timing for the three phases uses 1000 counts for
the signal integrate phase, 0 to 2000 counts for the integrate reference phase, and 1000 to 3000 counts
for the auto-zero phase, For digital readings of less than full count, auto-zero time gets the unused portion
of integrate reference. This makes a full measure cycle of 4000 counts (16,000 clock pulses). For three
readout updates per second, an oscillator frequency of 48 kilohertz is required.
The backplane frequency is the clock divided by 800. For three readout updates per second, the backplane
signal is a 60-hertz squarewave with a nominal amplitude of 5 volts. To turn on a segment, the segment
drive signal must be out of phase with the backplane signal.

test
The test output has two possible functions. It is connected to an internal supply through a 500-ohm resistor,
thus it can be used as the negative supply for externally generated segment drivers such as decimal points
or any other presentation the user may want to include On the LCD display. No more than a 1-microampere
load should be applied. The second function is the lamp test. When TEST is pulled high (VCC), all segments
are turned on displaying -1888. The TEST pin will sink about 10 milliamperes under these conditions.

external component selection guide
The integrating resistor, RX, should be large enough to maintain linear drive current from the buffer amplifier
and integrator, but small enough to minimize leakage currents. For a 2·volt scale, 1.8 megohm is near
optimum and for the 200·millivolt full scale, a 180-kilohm resistor is correct.
The integrating capacitor, CX, should be selected to give the maximum voltage swing without saturation.
For three readout updates per second (48-kilohertz clock), the nominal value for Cx is 0.047 microfarad;
for one readout update per second (16-kilohertz clock), the nominal value is 0.15 microfarads. Capacitor
values should be changed in inverse proportion to changes in oscillator frequency. The integrating capacitor
should have low dielectric absorption to prevent roll-over errors. Polypropylene capacitors give undetectable
errorf! at reasonable cost. At three readout updates per second, a 750-ohm resistor should be placed in'
series with Cx to compensate for comparator delay.
The size of the auto-zero capacitor, CZ, affects the system noise. On the 200-millivolt scale, a
0.32-microfarad capacitor is recommended. On the 2-volt scale, a 0.033-microfarad capacitor decreases
the recovery time from overload and is adequate for noise on this scale.
A reference capacitor, Cref, of 0.1 microfarad is suitable for most applications. If a large common-mode
voltage exists (reference-low pin is not at the same potential as analog COMMON) and a 200-millivolt
scale is used, a larger Cref is required to prevent roll-over error. A 1-microfarad capacitor will usually hold
the roll-over error to 0.5 count in this case.
For all ranges of oscillator frequency, a 50-picofarad capacitor is recommended and the resistor is selected
using the relationship f '" 0.45/RC.
R = 180 kilohm for a 48-kilohertz clock. The analog input voltage for a full-scale output (2000 counts)
is VI = 2 Vref.
