INTRODUCTION

The increase in complexity and diversity of Linear Integrated Circuits
over the last few years has necessitated a change in format in the
Fairchild Linear data books. In this data book we have included our
complete line of operational amplifiers and comparators, together with
other selected special purpose circuits of primary interest to the industrial market. Other Fairchild Linear data books will cover voltage regulators, consumer, and interface devices.
Fairchild continues to be a pioneer in Linear operational amplifiers. The
J.l.A709, J.l.A741 , and J.l.A747 are still industry standards a decade after their
introduction by Fairchild. These have been followed by many single,
dual, and quad devices intended to meet the increasing needs of our
customers.
Today Fairchild's state-of-the-art technology is providing devices like
the J.l.A714, precision op amp; the J.l.AF771 12/4, the industry's first set of
single, dual, and quad BIFET op amps; the J.l.A759 and J.l.A791 power op
amps; and the J.l.A7391 and J.l.A7392, precision DC motor speed control
circuits.
This data book presents complete technical data on Fairchild's I ine of
industrial linear integrated circuits. To expedite the designer's search
for the right devices to meet various system requirements, several
helpful aids are provided-selection guides by function, an LlC cross
reference identifying competitive devices with their Fairchild direct
replacements or nearest equivalents, and a package cross reference
for determining equivalent packaging within the industry. For the Hi
Rei customer, descriptions of Fairchild's Hi Rei processing and Matrix
VI are given in a separate section.

HI REL PROCESSING - MIL-M-38510/MIL STD-883
A unique "company", within Fairchild Linear, is totally dedicated to the processing of high reliability
products and to serving the special needs of the HI REL community. It consists of marketing, engineering, production control, manufacturing and quality assurance. Fairchild's HI REL processing facilities
are among the most modern and sophisticated in the semiconductor industry. Screening procedures are
set up to conform to the most recent version of MIL-STO-883" in conjunction with MIL-M-38510, which
establishes standardized requirements for design, material, performance, control and documentation
needed to achieve prescribed levels of device quality and reliability.
HI REL Unique" Program
Fairchild's Unique II program fills a longstanding need for a definite and comprehensive program
covering HI REL semiconductor products ... a program offering users a selection among multi-level
screening flows and reliability requirements ... a program providing clear and precise definitions on all
areas of contractual performance ... a program designed to reduce the high costs and delivery delays
normally associated with HI REL. The objectives and benefits of the'Unique II program for integrated
circuits are these:
•
•
•
•
•
•

Offers a- full spectrum of processing options, including full compliance JAN and 883 Classes S, B,
and C.
Offers full compliance with JAN MIL-M-38510 and emphasizes the importance of this program.
Accommodates the special needs of users' source control and specification control drawings.
Offers models to aid users in development of source control drawings.
Takes the mystery out of in-house processing to MIL-STD-883 and to MIL-M-38510 detail specifications. The Unique II program is definitive as to the similarities and differences in these requirements.
Provides users with alternatives that may be used when JAN slash sheets or QPLs are unavailable, or
for programs that demand the highest level of quality and reliability.

Fairchild offers a complete processing capability to fulfill requirements ranging from the least demanding to the most complex, including the following:
•
•
•
•
•
•

Scanning Electron Microscope (SEM) Inspection
Level A Visual
Bond Pull and Die Shear Testing
Read and Record and Ii Drift Parameters
Particle Impact Noise Detection (Pin-D) Testing
Group A, B, C and D Qualification Testing.

Standard Unique II processing flows are given on the following pages; special flows will be quoted on an
individual basis.

MATRIX VI- COMMERCIAL AND INDUSTRIAL RELIABILITY PROGRAM
Commercial and industrial users increasingly demand optimized quality and reliability for the semiconductor integrated circuits purchased for their systems. Specific factors - increased integrated circuit
usage per board, high costs for receiving inspection, pc board and systems repair, and the frequently
immeasurable cost associated with field failures - require the user to attain high quality and reliability
coupled with total cost. Matrix VI is designed to meet these user requirements.
Fairchild's Matrix VI Program offers a broad spectrum of screens and high technology/high volume
integrated circuit products to meet the user's quality and reliability requirements typically associated
with the commercial and industrial marketplace. There are two screening options for each package type,
each with a separate degree of reliability and cost level. To simplify a cost-effective analysis, reliability
factors have been assigned to each screening level. (See following pagesJ
It is the goal of Matrix VI to achieve the highest possible reliability consistent with the user's needs and to
avoid "over-buying". Cost-effective reliability is the essence of Matrix VI, the most comprehensive
program of its kind now offered to the industrial/commercial marketplace.

lor the DIP.
2. Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage.

3. 18 and los are measured at VCM = O. •
4. The input bias currents are junction leakage currents which approximately double for every 10°C imease in the junction temperature, Tj. Due to limited
production test time, the input bias currents measured are correlated to junction temperature. In normal operation the junction temperature rises above the

ambienttemperature as a result 01 internal power dissipation, PD' Tj = TA = ajA PD where ajA is the thermal resistance from junction to ambient. Use of a
heat sink is recommended if input bias current is to be kept to a minimum.
5. Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with common practice.

GENERAL PURPOSE OPERATIONAL AMPLIFIERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The ,..Al0l and ,..A201 are General Purpose monolithic Operational Amplifiers
constructed using the Fairchild Planar' epitaxial process. Thev are intended for a wide range of analog
applications where tailoring offrequency characteristics is desirable. The ,..Al0l and ,..A201 compensate
easily with a single external component. High common mode voltage range and absence of "Iatch-up"
make the ,..AI 01 and ,..A201 ideal for use as voltage followers. The high gain and wide range of operating
voltages provide superior performance in integrator, summing amplifier, and general feedback applications. The ,..Al0l and ,..A201 are short-circuit protected and have the same pin configuration as the
popular ,..A741 , ,..A748 and ,..A709.

GENERAL PURPOSE OPERATIONAL AMPLIFIERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The I£A101A, I£A201A and I£A301A are General Purpose monolithic Operational Amplifiers constructed using the fairchild Planar'" epitaxial process. These integrated circuits are
intended for applications requiring low input offset voltage or low input offset current. The accuracy of
long interval integrators, timers and sample and hold circuits is improved dueto the low drift and low bias
currents ofthe I£A 101 A, I£A201 A, or I£A301 A. Frequency response may be matched to the individual circuit
need with one external capacitor. The absence of "latch-up" coupled with internal short circuit protection
make the I£A101A, I£A201A and 1£A301A virtually foolproof.

NOTES:
1.' Rating applies to ambient temperatures up to + 70ClC. Above + 70Q C ambient, derate linearly at 6.3 mW/C.
2. For supply voltages less than ±15 V, the absolute maximum input voltage is equal to the supply voltage.
3. For 102 and 110 continuous short circuit is allowed for case temperature of + 125 0 C and ambient temperature to +700 C. For 302 and 310
continuous short circuit is allowed for case temperature to +70o C and ambient temperature to +5SoC. It is necessary to insert a resistor
greater than ~ kn in series with the input when the amplifier is driven from low impedance sources to prevent damage when the output is
shorted.
4. Increased output swing under load can be obtained by connecting an external resistor between the booster and V- terminals (see curve).

GENERAL-PURPOSE OPERATIONAL AMPLIFIERS
FAIRCHILD LINEAR INTEGRATED CIRCU ITS

GENERAL DESCRIPTION - The ,.Al07 General Purpose Operational Amplifier series is constructed
using the Fairchild Planar'" epitaxial process. Advanced processing techniques have reduced the 107

input current an order of magnitude below industry standards such as the ,.A709 while still replacing,
pin-for-pin, ,.A709, ,.AIOI, ,.AIOIA, and ,.A741. The ,.AI07, ,.A207, and ,.A307 offer better accuracy,
internal compensation, and lower noise for high impedance circuit applications while providing features similar to the ,.AIOIA. The low input currents allow the device to be used in slow-charge applications such as long period integrators, slow ramps, and sample-and-hold circuits. The JJ.A207 is identical to the ,.A 107 except that the ,.A207 performance is guaranteed from -25·C to +85·C while the
~A107 performance is guaranteed over a -55°C to +125°C temperature range. The IJ.A307 is available
in both TO-99 and 8-pin mini DIP packages and is guaranteed over a O·C to + 70C temperature range.

SUPER BETA OPERATIONAL AMPLIFIERS
FAIRCHILD LINEAR. INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The jLA10S Super Beta Operational Amplifier series is constructed using

the Fairchild Planar* epitaxial process. High input impedance, low noise, low input offsets, and
temperature drift are made possible through use of super beta processing, making the device suitable
for applications requiring high accuracy and low drift performance. The jLA10SA series is specially

selected for extremely low offset voltage and drift, and high common mode rejection, giving superior
performance in applications where offset nulling is undesirable. Increased slew rate without
performance compromise is available through use of feedforward compensation techniques,
maximizing performance in high speed sample-and-hold circuits and precision high speed summing
amplifiers. The wide supply range and excellent supply voltage rejection assure maximum flexibility in
voltage follower, summing, and general feedback applications.

Rating applies to ambient temperatures up to 70°C. Above 70°C ambient derate linearly at 6.3 mW/oC for metal can, 8.3 mW/oC for the
DIP, 5.6 mW/QC for the mini DIP and 7.1 mW/oC for the flatpak.
The inputs are shunted with back~to-back dio.des for overvoltage protection. Therefore, excessive current will flow if a differential input
voltage in excess of 1 V is applied between the inputs unless adequate limiting resistance is used.
For supply voltages less than ±15 V, the absolute maximum input voltage is equal to the supply voltage.
Short circuit may be to either supply or ground. Rating applies to operation up to the maximum operating temperature range.

GUARDING
Extra care must be taken in the assembly of printed circuit boards to take full advantage of the low input currents of the I£Al0B amplifier. Boards
must be thoroughly cleaned with TCE or alcohol and blown dry with compressed air. After cleaning, the boards should be coated with epoxy or
silicon" rubber to prevent contamination.
Even with properly cleaned and coated boards, leakage currents may cause trouble at 125°C, particularly since the input pins are adjacent to
pins that aro at supply potontials. This leakago can bo significantly reducod by using guarding to lowor the voltago differonce between the
inputs and adjacent metal runs. Input guarding of the B-pin TO-99 packago is accomplished by using a 10-pin pin circle, with the leads of the
device formod so that the holes adjacent to the inputs are ompty when it is insortod in tho board. Tho guard, which is a conductive ring
surrounding tho inputs, Is connected to a low impedance point that is at approximately the same voltago as the inputs. Leakage currents from
high voltago pins aro thon absorbod by tho guard.
.
The pin configuration of the dual in-line package is designed to facilitate guarding, since the pins adjacent to the inputs are not used (this is
different from tho standard I£A741 and I£Al01A pin configuration).

QUAD OPERATIONAL AMPLIFIERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The J.LA 124 series of Quad Operational Amplifiers consists
of four independent high gain, internally frequency compensated operational amplifiers
designed to operate from a single power supply or dual power supplies over a wide range
of voltages. The common mode input range includes the negative supply, thereby
eliminating the necessity for external biasing components in many applications. The output
voltage range also includes the negative power supply voltage. They are constructed
using the Fairchild Planar' epitaxial proc~ss.
• INPUT COMMON MODE VOLTAGE RANGE INCLUDES GROUND OR NEGATIVE SUPPLY
• OUTPUT VOLTAGE CAN SWING TO GROUND OR NEGATIVE SUPPLY
• FOUR INTERNALLY COMPENSATED OPERATIONAL AMPLIFIERS IN A SINGLE
PACKAGE
• WIDE POWER SUPPLY RANGE: SINGLE OF 3.0 V TO 30 V
DUAL SUPPLY OF ±1.S V to ±16 V
• POWER DRAIN SUITABLE FOR BATTERY OPERATION

QUAD OPERATIONAL AMPLIFIERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The .uA 148 series is a true quad .uA741. It consists of four
independent, high gain, internally compensated, low power operational amplifiers which
have been designed to provide functional characteristics identical to those of the familiar
.uA741 operational amplifier. In addition, the total supply current for all four amplifiers is
comparable to the supply current of a single .uA741 type op amp.

9A

Other features include input offset currents and input bias current which are much less
than those of a standard .uA741. Also, excellent isolation between amplifiers has been
achieved by independently biasing each amplifier and using layout techniques which mini·
mize thermal coupling. The .uA 149 series has the same features as the.uA 148 except that
it is decompensated to give a gain bandwidth product of 4 MHz typical at a gain greater
than 5.

HIGH-SPEED OPERATIONAL AMPLIFIER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

iENERAL DESCRIPTION - The !LA318 is a precision high-speed operational amplifier
esigned for applications requiring wide bandwidth and high slew rate. It features a factor
f ten increase in speed over general purpose devices without sacrificing DC performance.

he !LA318 has internal unity gain frequency compensation. This simpli1ies its application
ince no external components are necessary for operation. However, unlike most interally compensated amplifiers, external frequency compensation may be added for opmum performance. For inverting applications, feedforward compensation will boost the
lew rate to over 150 VII'S and almost double the bandwidth. Overcompensation can be
sed with the amplifier for greater stability when maximum bandwidth is not needed.
urther, a Single capacitor can be added to reduce the 0.1 % settling time to under 1 !Ls.

NOTES:
I. The maximum junction temperature of the 1-'A318 is 150"C for operating at elevated temperatures. The TO-5 peckage must be derated besed on a thermal
resistance of lSO"C/W, junction to ambient or 45"C/W, junction to case.
2. The inputs are shunted w~h back-to-back diodes for overvoltage protection. Therefore, excessive current will flow H a differential input voltage in excess of 1 V
is applied between the inputs unless some lim~ing resistance is used.
3. For supply voltages less than ±15 V, the absolute maximum input VOltage is equal to the supply voltage.

p-A740
FET INPUT OPERATIONAL AMPLIFIER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The jLA740 is a high performance monolithic FET Input Operational
Amplifier constructed using the Fairchild Planar* epitaxial process. It is intended for a wide range of
analog applications where very high input impedance ;s required and features very low input offset
current and very low input bias current. High slew rate, high common mode voltage range and
absence of latch-up make the jLA740 ideal for use as a voltage follower. The high gain and wide
range of operating voltages provide superior performance in active filters, integrators, summing
amplifiers, sample-and-hold circuits, transducer amplifiers, and other general feedback applications.
The jLA740 is short circuit protected and has the same pin configuration as the popular jLA741
operational amplifier. No external components for frequency compensation are required as the internal
6 dB/octave roll-off insures stability in closed loop applications.

IJA741
FREQUENCY-COMPENSATED OPERATIONAL AMPLIFIER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The I'A741 is a high performance monolithic Operational Amplifier
constructed using the Fairchild Planar" epitaxial process. It is intended for a wide range of analog
applications. High common mode voltage range and absence of latch-up tendencies make the I'A741
ideal for use as a voltage follower. The high gain and wide range of operating voltage provides superior
performance in integrator, summing amplifier, and general feedback applications.

IJA748
OPERATIONAL AMPLIFIER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The ",A748 is a High Performance Monolithic Operational Amplifier

constructed using the Fairchild Planar* epitaxial process. It is intended for a high wide range of analog
applications where tailoring of frequency characteristics is desirable. High common mode voltage range
and absence of latch-up make the ",A 748 ideal for use as a voltage follower. The high gain and wide
range of operating voltages provide superior performance in integrator, summing amplifier, and general
feedback applications. The ",A 748 is short·circuit protected and has the same pin configuration as the
popular ",A741 operational amplifier. Unity gain frequency compensation is achieved by means of a
single 30 pF capacitor. For superior performance, see ",A 777 data sheet.

IJA749
DUAL AUDIO OPERATIONAL
AM PLI FI ER/ PREAM PLI FI ER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The I'A749 consists of Two Identical High Gain Operational Amplifiers
constructed on a single silicon chip using the Fairchild Planar* epitaxial process. These 3~stage
amplifiers use Class A PNP transistor output stages with uncommitted collectors. This enables a variety
of loads to be employed for general purpose applications from dc to 10 MHz, where two high
performance operational amplifiers are required. In addition, the outputs may be wired-OR for use as
a dual comparator or they may function as diodes in low threshold rectifying circuits such as absolute
value amplifiers, peak detectors, etc.

POWER OPERATIONAL AMPLIFIER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The JLA759 is a high performance monolithic operational amplifier

CONNECTION DIAGRAMS

constructed using the Fairchild Planar* Epitaxial process. The amplifier provides 325 mA
output current and features small signal characteristics belter than the JLA741. The amplifier
is designed to operate from a single or dual power supply and the input common mode range
includes the negative supply. The high gain and high output power provide superior performance whenever an operational amplifier is needed. The JLA759 employs internal current
limiting, thermal shutdown and safe area compensation making it essentially indestructable.
It is intended for a wide range of applications including voltage regulators, audio amplifiers,
servo amplifiers and power drivers.

MOUNTING HINTS
Metal Can Package (!,A759HC/!,A759HM)
The !,A759 in the 8-PinTO-99 metal can package must be used with a heat sink. With ±15 V power supplies, the !,A759 can dissipate up to 540
mW in its quiescent (no load) state. This would result in a 100°C rise in chip temperature to 125°C (assuming a 25°C ambient temperature). In order
to avoid this problem, it is advisable to use either a slip on or stud mount heat sink with this package. II a stud mount heat sink is used, it may be
necessary to use insulating washers between the stud and the chassis because the case olthe !----...,.-.,...-o+VOUT

MULTI-PURPOSE PROGRAMMABLE OPERATIONAL AMPLIFIER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

DESCRIPTION - The IJA776 Programmable Operational Amplifier is constructed using the Fairchild
Planar' epitaxial process. High input impedance, low supply currents, and low input noise over a wide
range of operating supply voltages coupled with programmable electrical characteristics result in an
extremely versatile amplifier for use in high accuracy, low power consumption analog applications.
Input noise voltage and cJJrrent, power consumption, and input current can be optimized by a single
resistor or current source that sets the chip quiescent current for nana-watt power consumption or for
characteristics similar to the IJA741. Internal frequency compensation, absence of latch·up, high slew

PRECISION OPERATIONAL AMPLIFIER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The p.A777C is a monolithic Precision Operational Amplifier
constructed using a low-noise Fairchild Planar* epitaxial process. It is an excellent choice when
performance versus cost trade-ofts are possible between super beta or FET input operational amplifiers
and low-cost gen,ual purpose operational amplifiers. Low offset and bias currents improve system
accuracy when used in applications such as long-term integrators, sample and hold circuits and
high-source impedance summing amplifiers. Even though the input bias current is extremely low, the
p.A777C maintains full ±30 V differential voltage range. The internal construction utilizes isothermal
layout and special electrical design to maintain system performance despite variations in temperature
or output load. High common mode input voltage range, latch-up protection, short-circuit protection
and simple frequency compensation make the device versatile and easily used.

GENERAL DESCRIPTION - The IlA798 is a monolithic pair of independent, high gain, internally

frequency compensated operational amplifiers designed to operate from a single power supply or dual
power supplies over a wide range of voltages. The common mode input range includes the negative

supply, thereby eliminating the necessity for external biasing components in many applications. The
output voltage range also includes the negative power supply voltage. They are constructed using the
Fairchild Planar' epitaxial process.

DUAL INTERNALLY-COM PENSATED
OPERATIONAL AMPLIFIER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The I'A1458h,A1558 are a monolithic pair of Internally Compensated
High Performance Amplifiers constructed using the Fairchild Planar* epitaxial process. They are
intended for a wide range of analog applications where board space or weight are important. High
common mode voltage range and absence of "latch-up" make the I'A1458/I'A1558 ideal for use as
voltage followers. The high gain and wide range of operating voltage provides superior performance in
integrator, summing amplifier and general feedback applications.

(TOP VIEW)
PACKAGE OUTLINE 5S
PACKAGE CODE H

The I'A1458/I'A1558 are short-circuit protected and require no external components for frequency
compensation. The internal 6 dB/octave roll-off insures stability in closed loop applications. For single
amplifier performance, see the I'A741 data sheet.

Open loop voltage gain is defined as the voltage gain from the inverting input to the output,
Input bias current can be defined only for the inverting input. The non-inverting input is not a true "differential input" - as with a
conventional Ie operational amplifier. As such this input does not have a requirement for input bias current.
Current mirror gain is defined as the current demanded at the inverting input divided by the current into the non~inverting input.
Sink current is specified for linear operation. When the device is used as a gate or a comparator (non~linear operation), the sink capability
of the device is approximately 5.0 milliamperes.
When used as a non~inverting amplifier, the minimum output voltage is the VSE of the inverting input transistor.
Bandwidth and phase margin are defined with respect to the voltage gain from the inverting input to the output.
The quiescent current will increase approximately 0.3 mA for each non~inverting input which is grounded. Leaving the non~inverting input
open causes the apparent input bias current to increase slightly (100 nA) at high temperatures.
Power supply rejection is specified at closed loop unity gain, and therefore indicates the supply rejection of both the biasing circuitry and
the feedback amplifier.
Peak-to-peak restrictions are due to the variations of the quiescent dc output voltage. in the standard configuration as shown in the
peak-to-peak output voltage test circuit.

NORMAL DESIGN PROCEDURE
Output Q-Point Biasing
A number of techniques may be devised to bias the quiescent output voltage to an acceptable level. However, in terms of loop gain

considerations it is usually desirable to use the non-inverting input to effect the biasing as shown in Figures 2 and 3. The high impedance
of the collector of the non-inverting "current mirror" transistor helps to achieve the maximum loop gain for any particular configuration. It is
desirable that the non-inverting input current be in the 5.0 p.A to 100 p.A range.

V+ Reference Voltage (Figures 2 and 3)
The non-inverting input is normally returned to the V+ voltage (which should be well filtered) through a resistor, R r , allowing the input
current, Ir, to be within the range of 5.0 p.A to 100 p.A. Choosing the feedback resistor, Rf, to be equal to 1/2 Rr will now bias the amplifier
output de level to approximately:
V+
2
This allows for maximum dynamic range of the output voltage.

Reference Voltage Other Than V+ (Figure 4)
The biasing resistor Rr may be returned to a voltage (V r ) other than V+. By setting Rf = R r, (still keeping Ir between 5.0 p.A and 100 p.A) the
output de level will be equal to V r . Neglecting error terms, the expression for determining VOde is:

(Vrl (Rf)
VOUT =

Rr

where rjJ is the VBE drop of the input transistors (approximately 0.7

V@

+25°CI.

The error terms not appearing in the above equation can cause the de operating point to vary up to 20% from the expected value. Error terms
are minimized by setting the input current within the range of 5.0 /J-A to 100 p.A.

Gain Determination - Inverting Amplifier
The amplifier is normally used in the inverting mode. The input may be capacitively coupled to avoid upsetting the de bias and the output is

normally capacitively coupled to eliminate the de voltage across the load. Note that when the output is capacitively coupled to the load, the
value of 'sink becomes a limitation with respect to the load driving capabilities of the device. The limitation is less severe if the device is direct
coupled. In this configuration, the ae gain is determined by the ratio of At to Ri, in the same manner as for a conventional operational

amplifier:

Av

Rf

=

Ri

The lower corner frequency is determined by the coupling capacitors to the input and load resistors. The upper corner frequency will usually be

determined by the amplifier internal compensation. The amplifier unity gain bandwidth is typically 5.0 MHz and with the gain roll-off at 20 dB
per decade, bandwidth will typically be 500 kHz with 20 dB of closed loop gain or 50 kHz with 40 dB of closed loop gain. The exception to
this occurs at low gains where the inp!Jt resistor selected is large. The pole formed by the amplifier input capacitance, stray capacitance and the
input resistor may occur before the closed loop gain intercepts the open loop response curve. The inverting input capacity is typically 3.0 pF.

Non-Inverting Amplifier
Although recommended as an inverting amplifier, the 3301/3401 may be used in the non-inverting mode (Figure 3). The amplifier gain in this
configuration is subject to the same error terms that affects the output Q point biasing so the gain may deviate as much as ±20 % from that
expected. In addition, the resistance of the input diode must be included in the value of the input resistor. This resistance is approximately:

26

I; n,
where Ir is input current in rnA. The non-inverting gain expression is given,by:

Av

=

Rf

26

±20%.

Ri + Ir(mA)
The bandwidth of the non-inverting configuration for a given Rf value is essentially independent of the gain chosen. For Rf

= 510

kn the

bandwidth will be in excess of 200 kHz for non-inverting gains of 1, 10, or 100. This is a result of the loop gain remaining constant for these
gains since the input resistor is effectively isolated from the feedback loop.

NOTES:
1.

For supply voltage less than ±15 V, the absolute maximum input voltage is equal to the supply voltage.

Rating applies to ambient temperature up to 70"C. Above TA = 70°C, derate linearly at 6.3°C/W for the hermetic package (55) and 5.6°C/W for the
molded package (9T).
3. Short circuit may be to ground. one amplifier only. ISC = 45 rnA (Typical).

NOTES:

1.

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

2.

Rating applies to ambient temperatures up to 10°C. Above 70°C ambient derate linearly at 6.3 mW/oC for metal can; 8.3 mW/oC for DIP.

3.
4.

The offset voltage, offset current and bias current specifications apply for any supply voltage from a single 5 V supply up to ±15 V supplies.
The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a
1 mA load. Thus, these parameters define an error band and take in·to account the worst case effects of voltage gain and input impedance.
5. ,The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.
6. For input voltages greater than 15 V above the negative supply the bias and offset currents will increase - see typical performance curves.

This rating applies for ± 15 V supplies. The positive input voltage limit is 30 V above the negative supply. The negative input voltage limit is
equal to the negative supply voltage or 30 V below the positive supply, whichever is less.
Rating applies to ambient temperatures up to 70°C. Above 70°C ambient derate linearly at 6.3 mW/oC for metal can; 8.3 mW/oC for
mini DIP.
The offset voltage, offset current and bias current specifications apply for any supply voltage from a single 5 V supply up to ±15 V supplies.
The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a
1 mA load. Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.

must be derated based on a 1500 C maximum junction temperature. The low bias dissipation and the "ON-OFF" characteristic of the outputs keeps thechip dissipation very small (Po:5 100 mWl, provided the output transistors are allowed to saturate.
2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately 20 rnA independent of the magnitude of V+.
3. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP
transistors becoming forward biased and thereby acting as input diode clamps. In addition tiode action, there is also lateral NPN parasitic transistor
action on the IC chip. This transistor action can cause the output voltages of the comparators to go to the V+ voltage levellorto ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will reestablish when the input voltage, which
negative, again returns to a value greater than -0.3 V.
4. These specifications apply for V+ = 5.0 V and -55°C:::; TA:::; +125°C, unless otherwise stated. With the .uA239/.uA239A,all temperature specifications
are limited to -25° e:s TA:S +85° e, the ~A339/ ~A339A temperature specifications are limited to 0° e:s TA:S +70 0 e, and the :,A290t, ~A3302temperature

APPLICATION HINTS
The fJ.A 139 series are high-gain, wide-bandwidth devices which, like most comparators, can easily
oscillate if the output lead is inadvertently allowed to capacitively couple to the inputs via
stray capacitance. This shows up only during the output voltage transition intervals as the comparator changes states. Power supply bypassing is not required to solve this problem. Standard PC
board layout is helpful as it reduces stray input-output coupling. Reducing the input resistors to
< 10 kn reduces the feedback signal levels and finally, adding even a small amount (1.0to 10 mVI of
positive feedback (hysteresis I causes such a rapid transition that oscillations due to stray feedback
are not possible. Simply socketing the IC and attaching resistors to the pins will cause
input-output oscillations during the small transition intervals unless hysteresis is used. If the
input signal is a pulse waveform, with relatively fast rise and fall times, hysteresis is not required.
All pins of any unused comparators should be grounded.
The bias network of the fJ.A 139 series establishes a drain current which is independent of the magnitude of the power supply voltage over the range of from 2 V to 30 V.
It is usually unnecessary to use a bypass capacitor across the power supply line.
The differential input voltage may be larger than V+ without damaging the device. Protection
should be provided to prevent the input voltages from going negative more than -0.3 V lat 25° CI.
An input clamp diode can be used as shown in the applications section.
The output of the fJ.A139 series is the uncommitted collector of a grounded-emitter npn output
transistor. Many collectors can be tied together to provide an output ORing function. An output
pull-up resistor can be connected to any available power supply voltage within the permitted
supply voltage range and there is no restriction on this voltage due to the magnitude of the voltage
which is applied to the V+ terminal of the fJ.A139 package. The output can also be used as a simple
SPSTswitch to ground (when a pull-up resistor is not used I. The amount of current which the output device can sink is limited by the drive available (which is independent of V+I and the f3 of this
device. When the maximum current limit is reached (approximately 16 mAl, the output transistor
will come out of saturation and the output voltage will rise very rapidly. The output saturation
voltage is limited by the approximately 60 n saturation resistance of the output transistor. The
low offset voltage of the output transistor (1 mVI allows the output to clamp essentially to ground
level for small load currents.

~A734
PRECISION VOLTAGE COMPARATOR
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The "A734 is a Precision Voltage Comparator constructed on a single
silicon chip using the Fairchild Planar* epitaxial proces~. It is specifically designed for high accuracy
level sensing and measuring applications. The "A734 is extremely useful for analog·to-digital
converters with twelve bit accuracies and one mega-bit conversion rates. Maximum resotution is
obtained by high gain, low input offset current, and low input offset voltage. Its superior temperature
stability can be improved by offset nulling which further reduces offset voltage drift. Balanced or
unbalanced supply operation and standard TTL logic compatibility enhance the "A734's versatility.

TYPICAL APPLICATIONS
MONOSTABLE OPERATION
In the monostable mode, the timer functions as a one-shot. Referring

until the set time has elapsed, everi if it is triggered again during
this interval. The duration of the output HIGH state is given by
t = 1.1 R1 C1 and is easily determined by Figure 3. Notice that since
the charge rate and the threshold level of the comparator are both
directly proportional to supply voltage, the timing interval is independent of supply. Applying a negative pulse simultaneously to the
Reset terminal (lead 4) and the Trigger terminal (lead 2) during the
timing cycle discharges the external capacitor and causes the cycle
to start over. The timing cycle now starts on the positive edge of the
reset pulse. During the time the reset pulse is applied, the output
is driven to its LOW state.

to Figure 1 the external capacitor is initially held discharged by a
transistor inside the timer.

When a negative trigger pulse is applied to lead 2, the flip-flop is
set, releasing the short circuit across the external capacitor and

drives the outputHIGH.The voltage across the capacitor, increases
exponentially with the time constant T = R1C1. When the voltage
across the capacitor equals 2/3 VCC, the comparator resets the
flip-flop which then discharges the capacitor rapidly and drives the
output to its LOW state. Figure 2 shows the actual waveforms
generated in this mode of operation.
The circuit triggers on a negative..going input signal when the level
reaches 1/3 Vee. Once triggered, the circuit remains in this state
+Vcc-5 TO

When Reset is not used, it should be tied high to avoid any
possibility of false triggering.

DUAL TIMING CIRCUIT
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The jlA556 Timing Circuits are very stable controllers for producing
accurate time delays or oscillations. In the time delay mode, the delay time is precisely controlled by
one external resistor and one capacitor; in the oscillator mode, the frequency and duty cycle are both
accurately controlled with two external resistors and one capacitor. By applying a trigger signal, the
timing cycle is started and an internal flip-flop is set, immunizing the circuit from any further trigger
signals. To interrupt the timing cycle a reset signal is applied, ending the time-out.

ASTABLE OPERATION
When the circuit is connected as shown in Figure 4 (leads 2 and 6
connected) it triggers itself and free runs as a multivibrator. The
external capacitor charges through R 1 and R2 and discharges
through R2 only. Thus the duty cycle may be precisely set by the
ratio of these two resistors.

and the discharge time (output LOW) by:
t2 = 0.693 (R2) Cl
Thus the total period T is given by:
T = tl + t2 = 0.693 (Rl + 2R2) Cl

In the astable mode of operation, Cl charges and discharges between
1/3 VCC and 2/3 VCC. As in the triggered mode, the charge and
discharge times and therefore frequency are independent of the
supply voltage.

The frequency of oscillation is then:

PROGRAMMABLE TIMER/COUNTER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The /lA2240 Programmable Timer/Counter is a monolithic controller capable of producing accurate microsecond to five day time delays. Long delays, up to three
years, can easily be generated by cascading two timers. The timer consists of a time-t>ase oscillator,
programmable 8-bit counter and control flip-flop. An external resistor capacitor (RC) network sets
the oscillator frequency and allows delay times from 1 RC to 255 RC to be selected. In the astable
mode of operation, 255 frequencies or pulse patterns can be generated from a single RC network.
These frequencies or pulse patterns can also easily be synchronized to an external signal. The trigger, reset and outputs are all TIL and DTL compatible for easy interface with digital system. The
timer's high accuracy and versatility in producing a wide range of time delays makes it ideal as a
direct replacement for mechanical or electromechanical devices.

FUNCTIONAL DESCRIPTION
(Figure 1 and Block Diagram. page 1)
When power is applied to the pA2240 with no trigger or reset inputs. the circuit starts with all outputs HIGH. Application of a positive-going trigger pulse to TRIG. pin 11. initiates
the timing cycle. The Trigger input activates the time-base
oscillator. enables the counter section and sets the counter
outputs LOW. The time-base oscillator generates timing pulses with a period T = 1 RC. These clock pulses are counted by
the binary counter section. The timing sequence is completed
when a positive-going reset pulse is applied to R. pin 10.

mode. following to a trigger input.
Important Operating Information
•

Once triggered. the circuit is immune from additional trigger
inputs until the timing cycle is completed or a reset input is
applied. If both the reset and trigger are activated simultaneously. the trigger takes precedence.

Ground connection is pin 9.

•

Reset R (pin 10) sets all outputs HIGH.

•

Trigger TRIG (pin 11) sets all outputs LOW.

•

Time-base TBO (pin 14) can be disabled by bringing thl
RC input (pin 13) LOW via a 1 k resistor.

•

Normal Time-base Output TBO (pin 14) is a negativegoing pulse greater than 500 ns.
Note: Under the conditions of high supply voltages (Vce

pulse width of TBO may be too narrow to trigger the counter section. This can be corrected by connecting a 300 pF
capacitor from TBO (pin 14) to ground (pin 9).

In most timing applications. one or more of the counter outputs are connected to the Reset terminal with 81 closed (Figure 3). The circuit starts timing when a trigger is applied and
automatically resets itself to complete the timing cycle when

Counter-Output Programming
The binary-counter outputs, 00 ... 0128' pins 1 through 8
are open-collector type stages and can be shorted together to
a common pull-up resistor to form a wired-OR connection;
the combined output will be LOW as long as anyone of the
outputs is LOW. The time delays associated with each counter
output can be added together. This is done by simply shorting the outputs together to form a common output bus as
shown in Figure 3. For example, if only pin 6 is connected to
the output and the rest left open, the total duration of the
timing cycle, TO, is 32 T. Similarly, if pins 1, 5, and 6 are
shorted to the output bus, the total time delay is TO = (1 +
16 + 32) T = 49 T. In this manner, by proper choice of counter
terminals connected to the output bus, the timing cycle can
be programmed to be 1 T .;;; TO .;;; 255 T.

cuit connection of Figure 7. In this case, the VCC terminal
(pin 16) of Unit 2 is left open, and the second unit is powered
from the regulator output of Unit 1 by connecting the VREG
(pins 15) of both units together.

Ultra Long Time-Delay Application
Two tlA2240 units can be cascaded as shown in Figure 6 to
generate extremely long time delays. Total timing cycle of two
cascaded units can be programmed from TO = 256 RC to
TO = 65,536 RC in 256 discrete steps by selectively shorting one or more of the counter outputs from Unit 2 to the output bus. In this application, the Reset and the Trigger terminals of both units are tied together and the Unit 2 time base
is disabled. Normally, the output is HIGH when the system is
reset. On triggering, the output goes LOW where itremains for
a total of (256)2 or 65,536 cycles of the time-base oscillator.

The circuit of Figure 9 is designed for continuous operation.
It self-triggers automatically when the power supply is turned
on, and continues to operate in its free-running mode indefinitely. in astable or free-running operation, each of the counter outputs can be used individually as synchronized oscillators, or they can be interconnected to generate complex
pulse patterns.

ASTABLE OPERATION
The tlA2240 can be operated in its astable or free-running
mode by disconnecting the Reset terminal (pin 10) from the
counter outputs. Two typical circuits are shown in Figures 8
and 9. The circuit in Figure 8 operates in its free-running
mode with external trigger and reset signals. It starts counting and timing following a trigger input until an external reset pulse is applied. Upon application of a positive-going reset signal to pin 10, the circuit reverts back to its Reset state.
This circuit is essentially the same as that of Figure 3 with the
feedback switch Sl open.

Binary Pattern Generation
In astable operation, as shown in Figure 8, the output of the
pA2240 appears as a complex pulse pattern. The waveform
of the output pulse train can be determined directly from the
timing diagram of Figure 2 which shows the phase relations
between the counter outputs. Figures 10 and 11 show some

In cascaded operation, the time-base section of Unit 2 can be

of the complex pulse patterns that can be generated. The
pulse pattern repeats itself at a rate equal to the period of the
highest counter bit connected to the common output bus. The
minimum pulse width contained in the pulse train is determined by the lowest counter bit connected to the output.

For low power operation with supply voltages of 6 V or less,
the internal time base section can be powered down by connecting VCC to pin 15 and leaving pin 16 open. In this configuration, the internal time base does not draw any current
and the overall current drain is reduced by "" 3 mA.

OPERATION WITH EXTERNAL CLOCK
The pA2240 can be operated with an external clock or time
base by disabling the internal time-base oscillator and applying the external clock input to TBO, pin 14. The recommended
circuit connection for this application is shown in Figure 12.
The internal time base is de-activated by connecting a 1 kCl
resistor from RC, pin 13, to ground. The counters are triggered on the negative-going edges of the external clock pulse.
For proper operation, a minimum clock pulse amplitude of
3 V is required. Minimum external clock pulse width must be
;;;. 1 ps.

FREQUENCY SYNTHESIZER
The programmable counter section of the pA2240 can be
used to generate 255 discrete frequencies from a given timebase output setting using the circuit connection of Figure 13.
The circuit output is a pOSitive pulse train with a pulse width
equal to T, and a period equal to (N + 1) T where N is the programmed count in the counter. The modulus N is the total
count corresponding to the counter outputs connected to the
output bus. For example, if pins 1, 3 and 4 are connected together to the output bus, the total count is N = 1 + 4 + 8 = 13;
and the period of the output waveform is equal to (N + 1) T
or 14 T. In this manner, 255 different frequencies can be synthesized from a given time-base setting.

SYNTHESIS WITH HARMONIC LOCKING
The harmonic synchronization feature of the ttA2240 time
base can be used to generate a wide number of discrete frequencies from a given input reference frequency. The circuit
connection for this application is shown in Figure 14 (see
Figures 4 and 5 for external sync waveform and harmonic
capture range). If the time base is synchronized to (m)th
harmonic of input frequency where 1 ~ m ~ 10, the frequency fO of the output waveform in Figure 14 is related to the input reference frequency fR as

The circuit of Figure 14 can be used to generate frequencies
which are not harmonically related to a reference input. For
example, by selecting the external RC to set m = 10 and setting N = 5, a 100Hz output frequency synchronized to 60 Hz
power line frequency can be obtained.

STAIRCASE GENERATOR
The ttA2240 timer/counter can be interconnected with an
external operational amplifier and a precision resistor ladder
to form a staircase generator as shown in Figure 15. Under
Reset condition, the output is LOW. When a trigger is applied,
the op amp output goes HIGH and generates a negative-going
staircase of 256 equal steps. The time duration of each step
is equal to the time-base period T. The staircase can be
stopped at any level by applying a disable signal to pin 14,
through a steering diode, as shown in Figure 15. The count
is stopped when pin 14 is clamped at a voltage level';;;; 1.0 V.

DIGITAL SAMPLE AND HOLD
Figure 16 shows a digital sample and hold circuit using the
pA2240. Circuit operation is similar to the staircase generator described in the previous section. When a strobe input is
applied, the RC low-pass network between the Reset and the
Trigger inputs resets the timer, then triggers it. This strobe
input also sets the outputof the bistable latch to a HIGH state
and activates the counter.

ANALOG-TO-DIGITAL CONVERTER
Figure 17 shows a simple a-bit AID converter system using
the pA2240. Circuit operation is very similar to that of the
digital sample and hold. system of Figure 16. In the case of
AID conversion, the digital output is obtained in parallel
format from the binary-counter outputs with the output at
pin a corresponding to the most significant bit (MSB). Recycle time is "'" 6 ms.

The circuit generates a staircase voltage at the op amp output. When the level of the staircase reaches that of the analog input to be sampled, the comparator changes state, activates the bistable latch and stops the count. At this point, the
voltage level at the op amp output corresponds to the sampled analog input. Once the input is sampled, it is held until
the next strobe signal. Minimum recycle time of the system
is"'" 6 ms.

DIGITAL TACHOMETER TIME BASE
A digital tachometer requires a time-base generator to supply
two pulse outputs at specific intervals, e.g., every second. The
first pulse is a command (load) to transfer the accumulated
counts in the counter section into latches (memory); the second resets the counter to zero. A simple adjustable time base,
accurate to approximately ±O.5%, can be implemented using
the circuit in Figure 18.

(TOPVIEWI
PACKAGE OUTLINE SC
PACKAGE CODE H

Fairchild Planar* epitaxial process and is intended for use as a limiting or non-limiting amplifier,
harmonic mixer, or oscillator to 150 MHz. The low internal feedback of the device insures a higher

stability-limited gain than that available from conventional circuitry. Including the biasing network in
the same package reduces the number of external components required, thereby increasing the
reliability and versatility of the device.

package, held at a constant temperature by active temperature regulator circuitry. The transistor pair
displays the excellent matching, close thermal coupling and fast thermal response inherent in

monolithic construction. The high gain and low standby dissipation of the regulator circuit permits
tight temperature control over a wide range of ambient temperatures. It is intended for use as an
input stage in very-low-drift de amplifiers, replacing complex chopper-.stabilized amplifiers. It is also
useful as the nonlinear element in logarithmic amplifiers and multipliers where the highly predictable

exponential relation between emitter-base voltage and collector current is employed. The device is
constructed on a single silicon chip using the Fairchild Planar* process.

DIFFERENTIAL VIDEO AMPLIFIER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The I'A733 is a monolithic two-stage Differential Input, Differential
Output Video Amplifier constructed using the Fairchild Planar* epitaxial process. Internal series-shunt
feedback is used to obtain wide bandwidth, low phase distortion, and excellent gain stability. Emitter
follower outputs enable the device to drive capacitive loads and all stages are current-source biased to
obtain high power supply and common mode rejection ratios. It offers fixed gains of 10, 100 or 400
without external components, and adjustable gains from 10 to 400 by the use of a single external
resistor. No external frequency compensation components are required for any gain option. 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 general purpose video and
pulse amplifiers where wide bandwidth, low phase shift, and excellent gain stability are required.

IJA757
GAIN-CONTROLLED IF AMPLIFIER
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The j.LA757 is a monolithic high performance, Gain Controlled IF
Amplifier constructed using the Fairchild Planar* epitaxial process. The amplifier contains two sections
which may be operated independently, or in cascade, from audio frequencies to 25 MHz. The jl.A757
is intended primarily as a gain controlled, intermediate frequency amplifier in AM and FM communications receivers. It also has excellent performance when operated in FM receivers as a limiting
amplifier.

2.

For supply voltages less than +12 V, the absolute maximum voltage at either AGe terminal is equal to the supply voltage.
Rating applies to ambient temperatures up to 70 o e. Above 700 e ambient derate linearly at 8.3 mW/oC.
For 10.7 MHz met:lsurements, interstage capacitance and Section 2 output capacitance are tuned out. Pin 9 should be connected to GN D.

~A7391
DC MOTOR SPEED CONTROL CIRCUIT
FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The pA7391 is designed for precision, closed-loop, motor
speed control systems. It regulates the speed of capstan drive motors in automotive and
portable tape players and is useful in a variety of industrial control applications, e.g.,
floppy disc drive systems, data cartridge drive systems. The device is constructed using
the Fairchild Planar* epitaxial process.

CONNECTION DIAGRAM
12-PIN POWER PACKAGE
(TOP VIEW)
PACKAGE OUTLINE 9W
PACKAGE CODE P6

The pA7391 compares actual motor speed to an externally presettable reference voltage. The motor speed is determined by frequency to voltage conversion of the input signal provided by tachometer generator. The result of the comparison controls the duty
cycle of the pulse width modulated switching motor drive output stage to close the system's negative feedback loop.

TACH INPUT I-j

Thermal and over-voltage shutdown are included for self-protection, and a "stall-timer"
feature allows the motor to be protected from burn-out during extended mechanical
jams.

TESTING OPERATIONAL AMPLIFIERS
WHAT IS AN OP AMP?
An operational amplifier is a direct-coupled high-gain amplifier, often powered by both a positive
and a negative supply so that the output can swing both above and below ground. By itself, because
of the high gain (80 dB or much higher), op amp usefulness is limited due to saturation, with the output swung as far as possible toward one of the supplies. With feedback applied, in a closed-loop
configuration, the op amp becomes a useful device. Since the properties of the closed-loop circuit
depend primarily on characteristics of the feedback components ratherthan the op amp, and since
typical feedback components, i.e. resistors and capacitors, have high precision and low drift,
closed-loop op amp circuits can be very accurate and stable.

The name operational amplifier is derived from one of the original uses of closed-loop op amp circuits, performing mathematical operations in analog computers. Early op amps used a single,
ground-referenced inverting input, where a positive voltage change at the input caused a negative
change at the output. The more versati Ie, modern op amps have two floating inputs - one inverting
and one non-inverting. Since an op amp responds equally to the two inputs, the output depends on
the difference between the inputs, known as differential inputs. A common-mode signal, applied
equally to both inputs, is ignored since there is no difference between inputs. By grounding one of
the inputs, the differential amplifier becomes a ground-referenced amplifier.
With negative feedback applied to an inverting input, the op amp continually adjusts the output to
minimize (or null) the differential input voltage. Because the gain of the op amp is so high, the
nulled input voltage is always small, regardless of the output voltage. For example, if the gain is
100,000 and the output is at 10 V, the differential input is only 100 J.1.V, a negligible voltage. Thus, it
can be said that the op amp with negative feedback is continually adjusting the outputs to keep the
inputs at the same voltage.
MAJOR DC PARAMETERS
There are seven important parameters that are tested and guaranteed on all modern Ie op
amps. In the following discussions, input voltage refers to the differential voltage at zero
common-mode voltage.
Input Offset Voltage Vas
Ideally, the output voltage should be zero when the input voltage is zero, but practically, there
will always be small mismatches in the amplifier components. Input offset voltage is the input
voltage required to zero the output, typically a millivolt or two. Vas, usually caused by mismatches in the base-emitter voltages of the amplifier input transistors, is undesirable in a
direct-coupled circuit because the circuit will usually amplify it, causing a large dc error,
which is temperature-dependent.

To avoid the effects of input currents, Vas should ideally be measured at zero source impedance (resistance from each input to ground). For testing purposes, some low impedance,
usually 50 ohms, is used.
Input Bias Current 18
Although op amp inputs ideally draw no current, practically, some bias current must flow into
each input. For op amps with bipolar transistors at the input, 18 is the base current of the input
transistor, typically 100 nA. Where source impedance is low, 18 has no effect; but in highimpedance circuits, a voltage (18 X source resistance) will appear at the amplifier input. This
error is similar to Vas and is also temperature-dependent.
8-3

•

i

Because of the design of differential stages, the two Iss of an op amp vary with the input
voltage, but their sum remains constant. The parameter usually tested is the total input bias
current IS(Total) = ( IS(inverting) + IS(non-inverting)). The average input bias current specified on
data sheets is just IS(Total)/2.
Occasionally, it is necessary to measure the two input currents separately. To make IS(Total)
divide evenly between the two inputs and not in a random way, dependent on Vas, the standard convention is to null the op amp in a feedback loop.
Input Offset Current los
Because an op amp has differential inputs, many of the effects of the two input currents can
be eliminated if both currents are equal, since equal effects at both inputs would cancel. Practically, the two input currents cannot be made exactly equal, so the difference between them is
specified. The input offset current is the difference between the two input currents when the op
amp is nulled. In applications where the inputs are operated from equal source impedance, los
is the parameter of interest.
In op amps with a simple input stage, like the }J.A709 or }J.A749, los is dependent on the beta
match of the input transistors. In more complicated devices, like the }J.A741, los also depends
on matching the current sources that supply the input transistors.
High-Impedance Composite Input Offset Voltage Vas 10 k
The input offsets of an op amp are fully specified by either:
Vas, IS(inv), IS(ninv) or Vas, los, IS(Total)
In either case, common-mode and differential input voltages can be calculated for any source
resistances, equal or unequal. In applications with equal source resistors, Vas dominates at
low impedances and los dominates at high impedances. At some intermediate resistance,
Vas and los effects are about equal and may add or cancel, depending on their signs which
are statistically uncorrelated. If they add, the composite offset will be greater than Vas and
may even be greater than the data sheet limit for Vas. To guard against this possibility, a highimpedance composite input offset voltage at a specified source resistance, usually 10 k, is
tested and guaranteed. Vas 10 k is not an independent parameter of an op amp; it is a calculated number, determined by the interaction of the independent parameters Vas and los with
external source resistors.
Voltage Gain
The gain of an op amp, as with any other amplifier, is the ratio of a change in the output voltage to a change in the input voltage. Gain can be specified in V/V or in dB. The symbol AVOL is
used to indicate open-loop voltage gain, the gain of the amplifier without feedback.
Common Mode Rejection Ratio CMRR
Ideally, an op amp ignores common-mode signals. Practically, there will always be some
small response. The standard convention for measuring this response is to null the amplifier,
then measure the change in Vas when large common-mode voltages are applied. The
common mode rejection ratio CMRR is the ratio of change in Vas to the change in commonmode voltage, specified in dB. To avoid a minus sign (-100 dB, -70 dB), CMRR is often specified "upside-down" as the change in common-mode voltage over the change in Vas. Typical
op amps have 80 to 100 dB CMRR.

8-4

Power Supply Rejection Ratio PSRR
Power supply rejection ratio is a measure of the abi1ity of the op amp to ignore changes in the
power supply voltages. The change in Vas is measured as the supplies are varied. Power
supply rejection ratio PSRR is the ratio of the change in Vas to the total change in power
supply voltage. For example, if the supplies vary from ±5 V to±20 V, the total change is
40 - 10 = 30 V. PSRR is usually specified in p.VIV or sometimes in dB, in which case the
"upside-down" form is used. Typical op amps have 30 p.V IV (90 dB) PSRR.
MINOR DC PARAMETERS USUALLY SPECIFIED
Output Swing
Ideally, the output voltage of an op amp should be able to swing all the way to either supply.
However, real op amps saturate within a volt or two of the supplies, depending on how many
base-emitter junctions and/or saturated transistors are involved. Op amp output stages are
usually complementary-symmetry emitter followers, so output impedance is low, whether the
op amp is si nking or sourcing output current. To ensure that both the npn and pnp are operating, both positive and negative swing are tested, with an external resistor connected to load
the output.
Output Short-Circuit Current Isc
Most recent op amps have a protective current limit built into the output. If the output is short
circuited or otherwise overloaded, the output current limits at some safe value, typically
25 mA. The current limit circuits for each direction of current (sourcing and sinking) are independent and must be tested separately, although they are designed to limit at the same value.
Isc is generally tested under worst-case conditions. For example, an input voltage is applied
to cause the output to swing to positive saturation, but the output is then shorted to the negative supply and held there while Isc is read. This causes maximum power dissipation in the
output transistor.

Supply Current Is or Isup
The standby current of the amplifier is measured when the output is at zero. In modern op
amps that have no ground terminal, the standby current into the V+ lead is equal to the standby current out of the V-lead and could be measured at either terminal. In older op amps, such as the
p.A702, that do have a ground terminal, the currents must be measured separately.
Power Consumption
Power consumption is determined by multiplying the supply current times the total supply
voltage. This parameter is guaranteed by the Is test.
Offset Adjust VaS(adj)
Some op amps have a pair of offset adjust terminals. Zero offset voltage can be obtained by
adjusting a potentiometer connected between these terminals. Test each VaS(adj) terminal by
measuring Vas while the terminal is shorted to V-. This indicates the maximum effect of the
terminal on Vas.
DC STRESS TESTS
Data sheets always include "absolute maximum" limits on common-mode input voltage, differential input voltage, and supply voltage. To guarantee these ranges, any of several tests can be performed. Sometimes a measurement is taken during the test if there is some measurable indication
of a failure. Other times, certain voltages are simply applied and removed before the main test
sequence.
8-5

Common-Mode Stress
This is not usually tested. The inputs are moved over a large common-mode voltage range during
GMRR; since the absolute maximum range is only slightly larger, a separate test is usually
unnecessary.
Differential Stress (Input Leakage - IL)
In this test, the inputs are subjected to absolute maximum differential input voltage. All of IB(Total)
will flow in the more positive input and the more negative input should see nothing but leakage.
Breakdown occurs if the input stage is defective. Input leakage is often measured during the test.
Supply Stress
Supply current is measured under absolute maximum supply voltages.
Internal MOS Capacitor Test - Cap Stress
Many modern op amps include a small MOS capacitor on the chip to set the amplifier frequency
response. The silicon dioxide dielectric of the cap is made only thick enough to withstand the absolute maximum total supply voltage. To test the dielectric, maximum supplies are applied and the
circuit is swung to whichever state puts the full voltage across the cap. The output is often
measured. Typically, if the dielectric ruptures, the amplifier will latch up in an improper state; the
output will go negative when it should be positive.
AC PARAMETERS
Since ac parameters are not usually tested in production, only typical values are shown on the data
sheet. However, three common ac parameters should be recognized.
Risetime and Overshoot
The small-signal step response is a simple test that indicates both the bandwidth and stability of an
amplifier under specified conditions. The risetime is related to the bandwidth, and the overshoot is
a measure of stability.
Slew Rate
Slew rate is a large-signal phenomenon resulting from the capacitor connected to adjust the smallsignal frequency response. So that the capacitors can be small, they are usually connected to highimpedance nodes in the circuit, that receive dc bias from current sources. If the amplifier is to
reproduce a large signal, such as a 10 V step, the circuit no longer behaves accordi ng to its smallsignal model. The current source at the compensation node cannot pump enough current into the
cap to move the output far enough, fast enough. If current I is provided to the cap G, the output will
slew toward the final value at a slew rate dV/dt = I/G. Slew rate limiting (or rate limiting) occurs
with all large, fast signals when current to the capacitor is insufficient.
THE BASIC OP AMP TEST LOOP
All op amps are basically alike, high-gain differential amplifiers. The reason there are so manydifferent op amps is that no one circuit design can possibly optimize all the dc and ac parameters. Op
amps are designed to optimize a parameter (high gain, low power consumption, etc.) for particular
applications. Fortunately for test engineers, however, the similarities of all op amps are so great
that a single test Circuit can be used to perform all standard dc tests. This circuit, shown in Fig'ure
8-1, is the basic op amp test loop.

Basic Op Amp Test Loop

Performing all tests requires five power supplies: the V+ and V- supplies for the device under test
(OUT), a control voltage Vc applied at the loop control terminal, and supplies to run the nulling
amplifier, usually ±15 V or ±20 V.
Operation of the test loop, with all relays closed, is as follows:
• The inverting input of the nulling amplifier is the control terminal of the loop. The OUT output is
connected to the non-inverting input of the null amplifier.
• The null amplifier output controls the OUT input through the feedback divider.
• There is one inversion in the loop, provided by the OUT. Therefore, the null amplifier operates
with negative feedback.
• With negative feedback, the null amplifier continually adjusts its output to keep its input
voltages equal.
• Therefore, the null amplifier adjusts the loop output so that the OUT output follows the control
terminal.
The input node voltage, VN in Figure 8-1, is always 1/1 OOOth of the loop output voltage (actually it is
1/1 001th, but it is common to neglect the 0.1 % error). Thinking in reverse, the circuit has a closedloop gain of 1000 and any voltage VN appears 1000 times larger at the loop output. Since the input
voltages to the nulled op amp are always very small, the gain simplifies measurements.
Equations for VN
Figure 8-2 shows the OUT portion of the test loop, leaving out the 50 .n resistors since their effect is
negligible in this analysis. Vas is represented as a small voltage source moved outside the op amp.
Current flows into both inputs of the op amp. With VN adj usted by feedback to produce a OUT output of zero, and with Vas accounted for externally, no voltage exists between the op amp inputs;
zero in means zero out. VN equations can now be written for the various settings of K2 and K3.
K2 closed, K3 closed:

VN1 = Vas

The input bias currents have no effect because there is no source resistance.
K2 closed, K3 open:

VN2 = Vas - IB(ninv) x 10k

With only K3 open, VN is a composite voltage involving Vas and IB(ninv). To test IB(ninv), measure
VN2, then subtract it from VN1 (equal to Vas).

VN4 is the high-impedance composite input offset voltage. To measure los, subtract Vos from VN4.
Each relay setting combination provides an easy way to measure some important parameter of the
op amp. For a measurement of I B(tolal), measure VN3 and subtract it from VN2.
~VN=VOS + IB(inv) (10 k) + IB(ninv) (10 k) - Vos
= (IB(inv) + IB(ninv~(10 k)
= 18(total) (10k)

Testing Using the Op Amp Test Loop
For the following tests of op amp parameters, refer to the test loop schematic, Figure 8-1, whenever
necessary. All relays are normally closed.
Input Offset Voltage Vas
Set the loop control voltage Vc to zero. The nulling amplifier immediately adjusts the loop output to
zero the OUT output. By definition, the input node voltage VN equals Vas; therefore, the loop output is 1000 Vas. For example, if the loop output reads 1,0 V, Vas is 1.0 mV.
Input Currents (Separately)
Measure Vas. Then open K2 and K3 alternately and compute the changes in VN as previously described. Because 1000 VN is always read at the loop output, a voltage change t1VN = 1000X IB X 10k
will be measured. Thus, if IB is 100 nA, the measured change will be 1.0 V.
Total Input Bias Current IB(lotal)
This was explained in the previous section. Measure VN2; then measure VN3 and subtract. The
measured change at the loop output is 1000 X IB(IOlal) X 10 k. An alternate method to test IB(lolal) is
to open K1 and K4, tie pins 1 and 2 together, and use a current meter to read IB(tolal). The industry
trend is for dynamic testing, however, since there is some small inaccuracy associated with the
latter method.
8-8

High-Impedance Composite Input Offset Voltage Vas 10 k
Measure VN4 as previously described.
Input Offset Current los
Measure Vas. Then measure Vas 10 k and subtract. I1V = (1000) (los) (10 k).
Gain
In testing low-gain ac amplifiers, such as audio amplifiers, the normal procedure is to apply a
small, known input and measure the large ac output. When testing high-gain dc amplifiers, such
as op amps, the reverse procedure is used. The test loop is used to vary the output over a large,
known range, and the dc change at the input is measured.
A normal test for a OUT using ±15 V supplies is to measure the average dc gain over the output
range -10 V to +10 V. Since gain is always specified with a load resistor, pin 6 should be grounded.
Set Vc = -10 V; the null amplifier brings the OUT output to -1 0 V. Measure VN. Then set Vc to +1 OV;
the null amplifier brings the OUT output to +10 V. Measure the change in VN. For example, if the
gain is 100,000 and the total output change is 20 V (-1 OV to +10 V), the loop output change should
be (1000) (20/100,000) = 200 mV.
Note that the OUT is tested at the inverting input; therefore, if the output goes from -10 V to +10 V (a
positive change), a small negative change should be seen at the input.
As mentioned previously, gain is always tested with an external load resistor, often 2 k O. Since the
op amp output stage must provide current to this resistor, the output stage must dissipate power. If
the op amp is an IC, a thermal signal will then travel across the chip tothe input stage, where it mixes
with the true, circuit-related input signal. Depending on the relative sizes of the circuit and thermal
components, this may cause peculiar readings to occur during a gain test. If the thermal component partially cancels the circuit component, the change in VN will be smallerthan normal, indicating
a larger gain. If the two components cancel, no change in VN will be read, indicating an effective
gain of infinity. If the thermal component is larger than the circuit component, a wrong-polarity
change in VN will occur, indicating a "negative gain."
There is no general agreement in industry about the significance or seriousness of "negative gain."
Devices that show negative gain in a test circuit usually behave normally in customer applications.
Nevertheless, a device exhibiting a large negative gain may bequestionable. Fairchild's policy is to
allow a wrong-polarity reading of 20-100% of the right-polarity limit.1
To check the linearity of the op amp transfer function, gain is sometimes tested over two different
parts of the output range. That is, instead of performing a single test as the output swings from
-10 V to +10 V, gain is tested as the output swings from 0 Vto +10 V, and then from OV to -10 V. Such
testing will identify units that have very high gain over part of the output range and very low gain
over the other part of the range.
Common Mode Rejection Ratio CMRR
The definition of CMRR might imply that testing involves holding Vc at zero and opening K1, tying
pins 1 and 2 together to a voltage VCM, then varying VCM and reading the change in VN at the loop
output. However, this method does not provide accurate results. Because of the 50 0/50 k 0 feedback divider, only 99.9% of VCM appears at the inverting input of the OUT. Since there is no divider
at the non-inverting input, 100% of VCM appears there, causing a 0.1 % differential signal injected by
the unbalanced test circuit. This error, only 60 dB below VCM, is disastrous, for devices typically
have 80 to 100 dB CMRR.

The obvious solution is to add another 50 kfl resistor from the non-inverting input to ground, which
should attenuate VCM equally at both inputs to eliminate the differential error signal. The problem
now becomes one of accurately matching the dividers. Advanced analysis of the four resistors as a
bridge circuit indicates that, with careful matching, quite high CMRRs can be measured.
An easier solution eliminates the need for precisely matched pairs of precision resistors. Instead of
holding V+, V- and Vc constant and moving pins 1 and 2, perform the inverse procedure. For
example, to apply a VCM of +10 V, leave K1 closed and change V+from +15 V to +5 V. Then change
V- from -15 V to -25 V and change VC from 0 V to -10 V. From the poi nt of view of the OUT, this is
equivalent to the original method. The total supply voltage is still 30 V, the OUT output is still held at
the midpoint between the supplies, and both inputs are 10 V above that midpoint, which makes
VCM = +10 V. However, from the point of view of the bridge, no VCM has been applied, pins 1 and 2
are at ground as always, and VN is the routine differential input voltage of the OUT.
This method permits accurate measurement of any CMRR without matched resistors. There is no
need for a 50 k fl resistor at the non-inverting input, since it would only shunt the 50 fl resistor on all
tests.
In summary, to measure CMRR, raise V+, V- and Vc to VCM volts above nominal, and measure VN.
Then lower V+, V- and Vc to VCM volts below nominal and measure the change in VN.
Sometimes CMRR is tested with 10 k fl source impedances (K2 and K3 open). In this case, any
changes in los contribute to the total change in VN. A test with 10 k sources is not necessarily a
more rigid test than with 50 fl; the change in VN may be larger or smaller, depending on how the Vas
ahd los components interact.
Power Supply Rejection Ratio PSRR
The PSRR test is very direct and simple, with none of the problems that occur with CMRR testing.
Hold Vc at zero, set both supplies to minimum values, and measure VN. Then set both supplies to
maximum values and measure the change in VN. PSRR may also be tested with 10 kfl source
impedance.
Output Voltage Swings
Measure at pin 5, saturating the OUT output by applying a large differential input voltage.

There are three possible ways to saturate the OUT. The most direct way is to open K1 and K4 and
apply the voltage directly across pins 1 and 2. Anotherway is to open K4 only and apply a voltage at
pin 9. This voltage is divided 1000:1, so 20 V at pin 9 will apply 20 mV to the OUT input, sufficient
drive for almost any op amp. The third way is similar to the second except that all relays are closed
and the null amplifier applies the 20 V to pin 9. Set Vc to 15 V; the null amplifier will immediately try
to bring the OUT output to 15 V, but the OUT cannot swing all the way to V+. The null amplifier
output eventually saturates around 18 V and the OUT output also saturates as desired.
Since output swings are always specified with a load resistor, pin 6 should be grounded.
Output Short-Circuit Current Isc
This test involves the same procedure as in measuring voltage swing, except that instead of using
load resistor on pin 6, connect a current meter from pin 5 to ground or to the worst-case opposite
supply. When the OUT attempts to swing in response to the input, the current meter shorts the output and measures Isc.

8-10

Supply Current Is
Specifications usually indicate the OUT output should be zero, so set Vc to 0 and measure the
current into pin 3. The state of the output has little effect on the Is reading of recent op amps, biased
internally by current sources. However, in earlier devices like the MA709, Is is heavily dependent on
the output state, even with nothing connected to the output.
Offset Adjust VaS(adj)
The OUT of Figure 8-1 has no offset adjust pins. Devices with offset adjust pins have relays to
connect them alternately, usually to V-. Vc should be set to zero and a measurement taken at the
loop output. At the least, the measurement should guarantee that the adjust range is sufficient to
eliminate the Vas of the particular device being tested. A more rigid test might require enough
range to eliminate the worst possible Vas, even though the OUT has a lower Vas.
Common-Mode Stress
Open K1 and K4. Apply VCM directly to pins 1 and 2.
Differential Stress (lL)
Open K1 and K4. Apply voltage directly across pins 1 and 2. Measure leakage at more-negative
input.
Supply Stress
Perform supply current test at specified supplies.
Cap Stress
Test like output voltage swings, using specified supplies and swinging output to specified state.
Common Variations of the Basic Test Loop
The test loop is never used in the exact simplified form shown in Figure 8-1. Each op amp has
quirks that require some variations on the basic theme. The following are some common variations .
A C Compensation Capacitors
While ac stabilization of the test loop is a complex topic, in general, each type of op amp has its own
frequency response which mayor may not be externally adjustable. When preparing a test loop for
a particular device, it is necessary to use the frequency-response curves of the DUT and the null
amplifier to determine which stabilization scheme to use and to predict which capacitors will be
required.
Loop Output Noise Filter
A small RC noise filter with time constant around 1 ms is usually attached to the loop output and all
measurements taken through this filter. The waveforms at the filtered output often prove to be
much cleaner than the unfiltered version.
Source Resistors
Most general-purpose op amps are tested with 10 kn source resistors. However, op amps with very
low input currents may use 50 k, 100 k, 1 M, or even 10 M resistors for improved resolution.
Test Loop Gain
The most common form of the test loop, with 50 k!1/50 n resistor combination, gives a gain of 1000.
For certain tests, usually Vas (adj), the 50 kn is split into a 45 kn and a 5 kn resistor, and the 45 kn
resistor can be shorted with a relay to reduce the gain to 100. For devices with very low Vas, a feedback resistor of 500 kn can be used to give a gain of 10,000.

MOSFETs in Place of K2 and K3
Some premium devices, such as the MA108, MA156, and MA725, have extremely low IBIAS and/or
Vas. When testing these units, if reed relays are used for K2 and K3, difficulty may arise with the
low-level properties of the reeds. Typical problems include thermally-generated EMFs, leakage
current, and flexing of the reeds after closing. MOSFETs are usually a good substitute when reeds
prove unsatisfactory. The high contact resistance of FETs (1000) is not detrimental if the current
passing through them is small, i.e. 1 nA. Benefits include clean switching, no thermal offsets, no
leakage, no bounce, no microphonics, and no mechanical wear.
CONCLUSION
Because it works so well on the bench or in conjunction with high-speed automatic testers, the
basic op amp test loop circuit is used universally by manufacturers and others who must test operational amplifiers. The test loop is so accurate and easy to use that it benefits even those who test
only a few units on the bench.

OP AMP PARAMETERS AND APPLICATIONS
The selection of an operational amplifier for a given application requires a good understanding of
op amp specifications and parameters, and their significance in applications.
INPUT BIAS AND INPUT OFFSET CURRENT
Input bias current affects almost all applications of operational amplifiers, especially in high
impedance circuits. Although op amp inputs ideally draw no current, for op amps to operate
properly, it is necessary for some dc current (typically from pA to IlAI to flow into each input (Figure
8-3). The input stage of the op amp is ordinarily a differential amplifier with a dc current sourcethat
sinks current from the emitters (Figure 8-41. The op amp inputs are the base currents for the differential amplifier transistors. Because of the differential stage design, the two base currents vary with
the input voltage, but the sum remains constant. The parameter usually tested is the total input
current, Is (Total) = IS1 + IS2. The input bias current ISlAS specified on the data sheets, is the
average of the two input currents (Figure 8-3), and is primarily a function of the large signal current
gain hfe of the input stage.
Since, in reality, the two input currents cannot be made exactly equal, input offset current los
specifies the difference between these two currents (Figure 8-3). los is usually caused by mismatch
of the differential amplifier, which results in different input currents for the two bases. In an op amp
with a simple input stage, los is dependent on the beta match of the input transistors. In more
complicated cases, los also depends on matching the current sources of the input transistors.
Effects of Input Bias Current on Applications
The output offset voltage (Va 1 due to bias current is the same for both inverting and non-inverting
amplifiers (Figure 8-5). Equation 1 shows the formula for Va as a function of bias current (also see
Figure 8-6).
(1)
Va = IS1 R2 -IS2 R3 (1 + :~ )
For inverting and non-inverting operation, R3 is selected to minimize output offset without affecting gain.
When R3 equals R2 in parallel with R1,

R3 = R1 R2
R1 +R2
Substituting for R3 for Equation 1
Va = (lS1 - IS2) (R21
Va = los R2
When R3 = 0
Va = ISlAS R2

NOTES:
• For the inverting configuration, it is usually simple to make R3 equal to R1 in parallel with R2,
which reduces the output offset voltage to only los R2. However, if the application does not
require very low output offset voltage, or if the input bias current IBIAS is very low, make R3 = 0
and the output offset is simply IBIAS R2. Therefore, it is wise first to calculate the output offset
voltage produced by the op amp assuming R3 = 0, (I BIAS R2). If this offset is low enough for the
application, the use of one resistor is saved. Ifthe offset is too high, add R3 to the circuit and then
calculate offset (los R2) to see if it meets the specification.
•

In the non-inverting configuration, R3 is part of the signal source impedance, and, in some
cases, that source impedance is not well known, which complicates the minimizing of the output
offset. If the source impedance is known to be very low, then a known series resistor can be
added to make R3 = R1/R2. The limiting factor for increasing the value of this resistor is the
op amp input impedance. If a high value of resistor is used, say 1 MIl, and the amplifier
input impedance is around 9 MIl in the frequency range of interest, the result is a 10% drop in
signal gain.

•

Never forget the need for a dc current path to the op amp inputs. If the op amp is used in an ac
amplifier as shown in Figure 8-7, notice that R3 is required to provide a dc current path to the
non-inverting input. Without R3, the circuit just does not work! R3 is also necessary if the source
cannot supply the bias current.

•

A fixed offset is not usually much of a problem and extra input circuitry may be added to cancel
it. It is usually the drift of the offset with temperature, time, etc., which causes problems. Therefore, once an op amp with acceptable output offset voltage is found, it is necessary to investigate
the offset change as a function of temperature, supply voltage, time, etc., and assure that it will
not cause problems in a particular application. Most data sheets give input bias current and offset current as functions of temperature, supply voltage, and time, and also provide temperature
dependence curves.

Staircase Generator

Current-to-Voltage Conversion

Other Applications
Input bias current comes into effect in circuits where op amps act as buffers or amplifiers with a
charged capacitor as a source. Because of input bias current, the charge across the capacitor starts
draining even if the op amp input impedance is very high. Two examples are shown in Figures 8-8
and 8-9.
The sample and hold circuit shown in Figure 8-8 consists of a voltage Vin which charges a holding
capacitor C. When the electronic switch opens, the capacitor is expected to hold the voltage Vin and
the op amp simply acts as a buffer. The output of the op amp, therefore, should hold the value of Vin
at the level it was when the switch opened for as long as the switch remains open. Because of bias
current and other leakage, however, the held voltage gradually changes. This voltage changes at
the following rate:
IlV
Ilt

=

(2)
C

where I is input bias current plus the capacitor leakage.
Equation 2 determines how long a held voltage remains within specified accuracy of its original
value. In this sample and hold application, the effect of input bias current shows in the holding
time. For example, if the capacitor C = 1 ,uF, and the maximum permissible change of voltage IlV is
10 mV, using a ,uA741 C (IBIAS =0.5 ,uA) and neglecting other leakages, the holding time is expressed
as follows:
CIlV
1 X 10-6 X 10 X 10-3
Ilt = - - =
= 20 ms
I
0.5 X 10-6
With a ,uAF771 A (IBIAS = 100 pAl, a better holding time results.

Low input bias current is not the only criterion for sample and hold buffers; offset voltage drift is
another important parameter.
Equation 2 also applies in circuits where the voltage held is across a capacitor in a feedback loop
(Figure 8-9).
Another application where input bias current plays a role is in current-to-voltage conversion
(Figure 8-10).
8-15

•

INPUT OFFSET VOLTAGE
Ideally, when the input voltage of an op amp is zero, the output voltage should be zero. However,
even with no signal applied across the inputs of the op amp, a dc voltage difference exists between
the inputs, which is amplified, causing the output to be at a non-zero value. Input offset voltage Vas
is the input voltage required to zero the output. This applied voltage is the same magnitude as the
original offset from zero, but of the opposite polarity.
Essentially every mismatch between the signal flow of the inverting inputs and the non-inverting
input contributes to input offset voltage. The major contributor, however, is the VSE mismatch of
the differential input stage. Vas is generally in the 1 to 10 mV range for non-FET input op amps. Vas
is undesirable in a direct-coupled circuit, because it is usually amplified by the circuit, causing a
large dc error which is also temperature-dependent.

Effects of Offset Voltage on Applications
For inverting and non-inverting amplifier applications (Figure 8-5), the output voltage has a dc output level due to Vas. Output offset voltage is given by

Here are some examples that will give an idea of the range of values discussed.
For a gain of 10 in an inverting configuration,
R2 = 100 k!l, R1 = 10 kfl, R3 = 9 kfl
Using J.LA741C,
Vas (max) = 6 mV
las(max) = 200 nA
Output Offset = 86 mV max
Using J.LA714E,
VaS(max) = .075J.LV
laS(max) = 3.8 nA
Output Offset = .38 mV
Using J.LAF771A,
VaS(max) = 2.0 mV
laS(max) = 50 pA
Output Offset = 22 mV
The most objectionable factor of the input offset voltage and current is that they vary with temperature. Most op amp data sheets give input offset voltage values and temperature dependence
curves.

Offset Voltage Nulling
In some op amps, offset voltage may be nulled with only an external potentiometer to two device
leads (Figure 8-12). Usually what is happening internally is that oneside of the input stage differential amplifier gets more or less current than the other side and thus causes a VSE difference to null
the initial VSE mismatch.
Other Applications
If Vas is considered as a small dc voltage source connected to an ideal op amp (Figure 8-13), its
effect can be analyzed in almost every application. From Figure 8-13 it is apparent that, in comparator applications, the output does not change state until the inverting input is at least a Vas different
from the non-inverting input. That is, if a zero crossing detector is being designed and the noninverting input is connected to ground, the output would change state when the input reaches Vas
volts instead of zero volts.
High-Impedance Composite Input Offset Voltage
Common mode and differential input voltages can be calculated for any source resistances, equal
or unequal. In the case of equal source resistors, at low impedances, Vas dominates and at high
8-17

•

impedances, los dominates. At some intermediate resistance, Vos and los effects are about equal
and may add or cancel, depending on polarities. Ifthey add, the composite offset will be larger than
Vos alone, maybe even larger than the data sheet limit for Vos. To guard against this possibility,
a high-impedance composite input offset voltage is tested and guaranteed at some specified
source resistance, usually 10k. Thus, it is common practice on data sheets to say that Vos is guaranteed for all source resistances:s 10 k. Sometimes written Vos 10 k, this is not an independent op
amp parameter, but a calculated number determined by the interaction ofthetrue independent parameters Vos and los with external source resistors.
OPEN LOOP VOLTAGE GAIN (AS A FUNCTION OF FREQUENCY)
As with any amplifier, the gain of an op amp is defined as the ratio of the change in output voltage to
the change in input voltage causing it. AVOL is used to indicate open-loop voltage gain, the gain of
the amplifier without feedback. See Figure 8-14.

This is true only if the op amp has infinite or very high open loop gain. However, in practical op

It is important to take Equation 7 into consideration when high accuracy de operation is required
and when considering frequency response. For instance, if the op amp is a J.tA741 , connected in the
inverting configuration (Figure 8-15) with R2/R1 == 100, AVOL == 104 at 100 Hz as determined from the
curve of Figure 8-16. From Equation 7, the error in assuming VourlVlN == 100 at 100 Hz is given by:

Note that when the open loop voltage gain is equal to the reciprocal of the feedback ratio
(R2 + R1 )/R1, the amplifier gain drops by 6. dB.
Choosing the Right Op Amp AVOL
Use the following simple rule. For a dc closed loop gain y and a decrease in gain of no more than
x per cent at a given maximum signal frequency f max. an op amp is needed with an AVOL at f max
given by:
AVOL2

100(1 + y) -(y+1)

(8)

x
For example, to achieve a dc closed loop gain of 100 with a decrease in gain of only 10% at 10 kHz,
an operational amplifier is required with an AVOL at 10kHz of at least
100 (1 + 100) _ 100 + 1 == 911
10
One possibility is the J.tA725 which has an AVOL of 1000 at 10 kHz with the proper compensation.
The graph in Figure 8-17 is also helpful in choosing the right op amp and can be used for inverting
or non-inverting configurations. The horizontal axis is the reciprocal of the feedback ratio

(R2 + R1 )/R1 in dB. Thevertical axis is the minimum Avouequired to be within 1, 3, 60r 10 dB ofthe
dc or ideal closed loop gain, VourlVlN. For example, if R2 = 9 kfl and R1 = 1 kfl, (R2 + R1 )/R1 = 20
dB. At the frequency where the AVOL of the op amp is 28 dB, the closed loop gain will be 3 dB down
from its dc value R2/R1. Therefore, to insure that amplifier gain does not fall off by more than 3 dB at
f max, choose an op amp with AVOL > 28 dB at f max.
Open loop voltage gain is not the only parameter that affects high frequency operation, however.
Slew rate must also be considered.

SLEW RATE
Slew rate is the maximum rate of change of output voltage with respect to time, usually specified
in volts per microsecond. For example, a 0.5 V/p.s slew rate means that the output rises or falls
no faster than 0.5 V every microsecond. Slew rate is also sometimes specified indirectly in data
sheets as output voltage swing as a function of frequency or as voltage follower large-signal
pulse response.
Causes of Slew Rate
Slew rate is a large-signal phenomenon caused by current limiting and saturation of an op amp
internal stage. That limited current is the maximum current available to charge the compensation
capacitance network, the capacitor connected to high-impedance nodes in the circuit to adjust
small-signal frequency response. The voltage across the capacitor rises at a rate,

;).V

I

;)'t

C

(9)

This capacitor charging rate is reflected at the output and causes slew rate limiting. Slew rate limiting therefore occurs with large input signals that saturate the internal stages.

Effect of Slew Rate on Applications
In a simple application using a p.A741 as a comparator (Figure 8-18), the output will go to about
-14 V and then to +14 Veach time the input signal crosses zero volts. The p.A741 has a typical slew
rate of 0.7 VI p's, determined under electrical specifications or calculated from the slope of the output curve in Figure 8-19. Therefore, the p.A741 output will go to +14 V from -14 V in
28 V = 40 p's
0.7 VI P.s
If the full 28 Voutput swing is desired, the input signal must have at least 40 P.s between zero crossings. That is, the maximum input signal frequency should be 1/(2 x 40 p.S) or 12.5 kHz assuming
50% duty cycle. Even at that frequency, the output is triangular instead of square wave. For higher
frequencies or a more square wave output, an op amp with a faster slew rate is needed.
As another example of the effect of slew rate, consider the simple amplifier with a gain of two in
Figure 8-20. Again, the p.A741 is used. Its open loop voltage gain as a function of frequency curve
(Figure 8-16) indicates that the amplifier circuit will operate with a gain of two up to about 80 kHz.
What is the maximum input signal voltage that may be used up to 80 kHz? If the output is to be an
undistorted sine wave, A sin wt, then the rate of change of the output is

and the maximum rate of change of the output is Aw. The minimum slew rate of the operational
amplifier, therefore, must be equal to Aw. Thus, with w = 2rr(80 x 103 ) = 503000 and the slew rate of
the MA741 typically 0.7 V/MS, the maximum output swing A of the sine wave without distortion is
slew rate
w

0.7 V/J+s = 1.4 Vpk

or 2.8 Vpk-pk
The maximum input signal should, therefore, be less than 2.8/2Vpk-pk. The maximum output swing
can also be easily read from the output voltage swing as a function of frequency curve on the data
sheet (Figure 8-21). From this curve, the maximum output swing without distortion can be determined for different frequencies.
Summary
In applications where square wave outputs (comparators, oscillators, limiters, etc.) are expected, it
is important to remember that the op amp output takes some time to change from one value to
another. That time, which usually limits the maximum frequency of operation, is determined by the
change of output voltage divided by the slew rate.
In applications where the output should be free of distortion, the slew rate determi nes the maximum
frequency of operation for a desired output swing. The required slew rate can be determined by a
simple formula. For a desired undistorted output voltage swing Vpk at a maximum frequency f max ,
an op amp is needed with a slew rate given by
slew rate> 2rr f max V pk

Figure 8-22 gives the slew rate req ui red for different output swi ngs at different freq uencies. Another
easy way to choose the right op amp is to check the data sheet curves of output voltage swing as a
function of frequency (Figure 8-21). However, these curves are typical and slew rate varies as a
function of supply voltage. Slew rates at different supply voltages are usually shown on the data
sheet.
In some applications such as DIA or AID converters, slew rate is not the only criterion for fast
response. The settling time is another parameter to consider. High slew rate op amps sometimes
have associated overshoot and ringing which may cause the output to take longerto reach asteady
state than with slower slew rate op amps.

INPUT IMPEDANCE
The major factors in op amp input impedance are input resistance and input capacitance. Input
resistance, or differential input resistance, usually specified in the data sheets, is the small signal
resistance measured between the inverting and non-inverting inputs of the op amp. Input capacitance is the capacitance seen between the same two inputs (see Figure 8-23).
Effects of Input Impedance on Applications
The input impedance of an amplifier circuit with feedback is not only dependent on theop amp, but
also on the circuit configuration.

where AVOL (wi is the open loop gain of the op amp and Z is the op amp input impedance. (See paragraph on Open Loop Voltage Gain as a Function of Frequency. I
As seen in Equation 12, the amplifier input impedance is equal to at least the op amp impedance and
is usually much higher, due to high open loop gain.
For an op amp to operate properly, it is necessary to supply a certain dc current at the inputs. That
current is given in the data sheets as input bias current and ranges in value from pA to!J.A depending
on the op amp. In the non-inverting configuration of Figure 8-24, if VIN has a series resistance of
1 Mfl and the input bias current of the op amp is 0.5 !J.A, there is a dc drop across the 1 Mil series
resistance of 0.5!J.A X 1 Mfl = 0.5 V. This is independent of the signal (VIN) amplitude. IfVIN is 1 V,
there is 1 - 0.5 = 0.5 V at the non-inverting input. However, it is erroneous to assume that the op amp
input impedance is 1 Mfl just because there is a straight voltage division. The drop is caused by
input bias current and not by input impedance. If an ac signal is riding on the 1 V dcvalue of VIN, the
ac amplitude is not halved and only a 0.5 V offset is there constantly due to bias current. The signal
amplitude is affected by the 1 Mfl series resistance and the op amp input impedance. However, dc characteristics are usually more important to consider than input impedance.

In this configuration, the effect of the op amp input impedance is minimal. The input impedance is
at least R1; at high frequencies, as AVOL decreases, the input impedance increases and the value of
R2 (Z + R)/AvOL Z becomes comparable to that of R1.
For all practical applications, however, it is safe to assume that the input impedance is just R1.
Again, remember that a constant dc bias current is required at the inverting input to operate the op
amp. The dc bias current limits the increase in value of R1. The higher the value of R1, the greater
the magnitude of the dc offset voltage occurring at the output.
Another interesting point concerning Equation 13 is that the effect of increased input impedance at
higher frequencies (AVOL decreases in the denominator) is very similar to an inductance effect,
usually referred to as Miller inductance. See Fairchild Application Note 321, "Operational Amplifiers as Inductors," for more detail.

USE OF OP AMP PARAMETERS IN DESIGN STEPS
The most important operational amplifier parameters have been presented and defined. These
parameters are available on the data sheets for individual op amps and are useful in circuit design
as well as determining which op amp to use for a specific application. Data sheet information can
be used to determine circuit stability and, through a few simple steps, op amp selection for inverting and non-inverting configurations.

CIRCUIT STABILITY
Circuit stability can easily be determined by following one simple rule and referring to the phase
response and open loop voltage gain curves on the op amp data sheets.
One consideration in determining circuit stability is the open loop voltage gain AVOL (W) of the
op amp, the ratio of the change in output voltage to the change in input voltage. Open loop voltage
gain versus frequency is readily available from the data sheets (Figure 8-16).
It is next necessary to consider the transfer functions for the inverting and non-inverting configurations shown in Figures 8-27 and 8-28. They can be expressed by the following equations:

ij

y;;-=

(

From these transfer functions, as well as from feedback theory, the stability of the inverting and
non-inverting configurations can be determined by following this simple rule. The circuits will be
stable if the magnitude of the term

is less than unity when its phase angle reaches 1800 • Stated another way, the phase angle of the
above term must be less than 1800 when its magnitude reaches unity. This rule is illustrated in the
following example.
Amplifier and Voltage Follower Stability
In amplifiers where Z2 and Z1 are resistive, the circuit stability depends mainly on AVOL (W) because there is no phase shift in 1 + (Z2/Z1). For example, in the circuit of Figure 8-29, for R2 = R1,

1 + ~ = 2 L 00
Z1
When AVOL (w) = 2,
AVOL (w) = 1
1 + Z2
Z1

From the open loop voltage gain curve (Figure 8-30), it is apparent that Avo L (w) = 2 at about 500 kHz
with C c= 30 pF. In Figure 8-31, note that the phase shift of the Avo L (w) is close to 180 0 at 5 MHz;
therefore the circuit is potentially unstable or oscillatory. The phase is close to 110 0 at 500 kHz.
Therefore the compensation, Cc= 30 pF, wouldbe used instead of Cc= 3 pF since with Cc= 3 pF,
AVOL

(W)

(5 MHz) = 1 L 1800 (unstable)

and with Cc = 30 pF,
AVOL

(500 kHz) = 1 L 110 0 (stable)

Summary
To determine stability for a resistive feedback circuit, the frequency at which AVOL (W) is equal to
1 + (R2/R1) is found on the open loop voltage gain curve. At that frequency, the ratio

The phase shift at that frequency is then read on the op amp phase response curve, If the phase
shift is less than 180 0 , the configuration is stable; if it is more than 1800 , the configu ration is unstable. Often the results of these computations are given in the data sheet as frequency response
for various closed loop gains using recommended compensation networks (Figure 8-32).
When Z2/Z1 is non-resistive as in integrators and differentiators, the same rule holds but the
phase response of both AVOL (W) and 1 + (Z2/Z1) must be considered. For more information
on stability rules for integrators and differentiators, see Fairchild Application Note 289, "Applications of the /-LA741 Operational Amplifier."
DESIGN STEPS FOR INVERTING AMPLIFIERS
The first step in op amp selection is to establish circuit specifications necessary for the application .
For the purpose of discussion, the following specs are assumed:
Gain = A =-9
Minimum 3 dB down frequency fc = 10 kHz
Maximum input signal amplitude V1 = 2 Vpk-pk
Maximum dc output offset voltage Vo (max) = ± 25 mV
Input resistance RIN = 10 kfl
DC drift from 0 to 70 0 ~ Vo (max) :5: 15 mV
Step 1:

Circuit Configuration

Using the inverting circuit of Figure 8-33, from Equation 6:
VOUT = -R2 =A=-9' R2 = 9
VIN
R1
' R1
Step 2:

Frequency Response

The first op amp specification to check is the minimum open loop voltage gain, AVOL, needed to
meet the amplifier frequency response requirement. This is easy to do by using the graph in Figure
8-17. Since R2/R1 = 9, then (R2 + R1 )/R1 = 10; locate the 10 ratio (20 dB) on the (R2 + R1 )/R1 axis.
Go up to the 3 dB line and read, on the vertical axis, the minimum AVOL required, 28 dB. Therefore,

Figure 8-34

to insure that amplifier gain does not fall off by more than 3 dB at fe, the op amp must have an open
loop gain of:
(First Requirement) AvaL 2': 28 dB at fe (10 kHz)
Step 3: Output Swing
Since the maximum input signal amplitude is 2 Vpk-pk, the maximum output swing will be 18 Vpk-pk.
Therefore, an op amp is needed with a slew rate fast enough to give 18 Vpk-pk up to 10kHz. By
checking Figure 8-34, it is apparent that an op amp is required with:
(Second Requirement) slew rate 2': 0.8 V/J.l.S
Step 4:

Maximum DC Output Offset Voltage Va

The dc output offset voltage, Va, for the circuit in Figure 8-33 is given by the following derivations
from Equation 4:
For R3 = 0
Va = (1

+ :~)

Vas

+ ISlAS

R2

(16)

For R3 =(R1 in parallel with R2)
Va = (1
where
Vas

+ :~)vas + R21as

( 17)

= input offset voltage

ISlAS = input bias current

los

= input offset current

Unless the output offset voltage spec is very wide, it is usually more economical to add R3 than
to use a very low input bias current op amp. For the example in this discussion, R3 = (R1 in parallel
with R2). From Equation 16 it can be seen that the Va value will be low when R2 is small; therefore,
the smallest possible value should be chosen for R2.
8-28

For the inverting configuration, the input resistance RIN is at least R1. Therefore, choose R1 so that
R1 ;:::: RIN ;:::: 10k!1
From the above and Step 1, R2/R1 = 9 and R1 ;:::: 10 k!1; therefore when R1 is 10 k!l, R2 = 90 k!l,
and R3 = 9 k!1. Equation 16 becomes
Va = (1

+ 9)

Vas

+ (90 x

103) los

Thus, an op amp is needed such that Vas and los give:
(Third Requirement) 10 Vas

+ (90 x

103) los = VO(max):5 25 mV

To simplify the search for an op amp to meet this requirement, look first for one that has the following specifications:
Vas <

los <
Step 5:

VO(max) = 270 nA

Drift is given by:

+ (90 x

103) Alos:5 AVO(max} (15 mY)

where AVOS and Alas are the changes in input offset voltage and input offset current over the 0 to
70 0 temperature range.

DESIGN STEPS FOR NON-INVERTING AMPLIFIERS
The design steps for nori-inverting amplifiers are similar to those for inverting amplifiers. For this
example, the following specifications are assumed:
Gain=A=10
Minimum 3 dB down frequency fc = 10 kHz
Maximum input signal amplitude V1 = 2 Vpk-pk
Input resistance RIN = 5 M!l minimum
Maximum dc output offset voltage VO(max) = ± 25 mV
DC drift from 0 to 70 0 AVO(max):5 15 mV
Step 1:

Circuit Configuration

For the non-inverting circuit of Figure 8-35, the equation for the gain is
VOUT = R2 + R1 = A = 10
VIN
R1
Step 2:

Frequency Response

As with inverting amplifier design, the first op amp specification to check is the minimum open loop
voltage gain, AVOL, needed to meet the amplifier frequency response requirement. This is easy to
do from the graph in Figure 8-17. Since (R2 + R1 }/R1 = 10, locate the 10 ratio (20 dB) on the
(R2 + R1 }/R1 axis. Go up to the 3 dB line and read, on the vertical axis, the minimum AVOL required,

28 dB. Therefore, to insure that amplifier gain does not fall off by more than 3 dB at fe, the op amp
must have an open loop gain of:
(First Requirement)

AVOL 2': 28 dB at fe (10 kHz)

Examination of the open loop voltage gain versus frequency curves on various op amp data sheets
will quickly determine which devices will meet this requirement. Figure 8-36 is a good example. An
op amp with a gain bandwidth product of 250,000 (28 dB X 10kHz) will do the job, assuming the op
amp has just one pole.
Step 3:

Output Swing

Since the maximum input signal amplitude is 2 Vpk-pk, the maximum output swing will be 20 Vpk-pk.
Therefore, an op amp is needed with a slew rate fast enough to give 20 Vpk-pk up·to 10kHz. From
Figure 8-37, it is apparent that an op amp is required with:
(Second Requirement)
Step 4:

slew rate 2': 0.85 V/p.s

The input impedance for the non-inverting configuration is given by Equation 13:

where Z is the op amp input impedance and R3 «

The op amp for this design must satisfy the amplifier input impedance requirement of 5 M!1 up to
at least 10kHz. In step 2, it was determined that the op amp must also have an AvaL of no less than
28 dB (or 25 VIV) at 10 kHz. Therefore, the required op amp must have an imput impedance (Z) at
10 kHz of at least the following:

From curves,such as Figure 8-25, of input resistance and input capacitance as a function of frequency, it is easy to select an op amp to meet the input impedance requirement.
Step 5:

Maximum DC Output Offset Voltage, Va

The dc output offset voltage, Va, for the circuit in Figure 8-35 is again given by following Equa16 and 17.
For R3 = 0
Va =

~ + :~) Vas + IBIAS R2

For R3 =(R1 in parallel with R2)
Va =(1

+:~) Vas + R21as

( 17)

where
Vas = input offset voltage
I BIAS = input bias current
las = input offset current
Unless the output offset voltage spec is very wide, it is usually more economical to add R3 than to
use a very low input bias current op amp. For the example in this discussion, R3 = R111 R2. From
Equation 16, it can be seen that the Va value will be low when R2 is small; therefore the smallest
possible value should be chosen for R2.
The minimum limit to this value is dependent on the capability of the op amp to drive R2. Since op
amp parameters usually specify a load resistor of 2 k!l or 10 k!l, R2 should be larger than 10 k!1.
From steps 1 and 4:
R1 + R2 = 10 and R3 «

Therefore, choose R1 = 10 k!l; then R2 = 90 k!l and R3 = 9 k!l and Equation 18 becomes

Thus, an op amp is needed such that Vos and los give:
(Fourth Requirement) 10 Vos

To simplify the search for an op amp to meet this requirement, look first for one that has the

where 11 Vos and I110s are the changes in input offset voltage and input offset current over the 0 to
70° temperature range.
FINAL HINTS IN CHOOSING THE RIGHT OP AMP
It is usually best to start by finding the op amps that meetthefirst andsecond requirements; this will
eliminate many. Then check the good ones against the remaining requirements starting with the
lowest cost op amp. There are usually other specifications such as supply voltage and current,
supply rejection, load current, common mode rejection, etc., that should be considered. However,
the op amps that meet the above requirements will narrow down the field of choice to only a few,
which can then be checked further to see if they meet the rest of the specifications.
