wall chart. We hope you’ll refer to this selection guide often and that it
provides you with a better understanding and appreciation of op amps
and their many applications.
Selecting an op amp is no trivial task: with so many different types of
amplifiers, categories, architectures, and parameters to choose from, the
process can be difficult. Each customer and application requires slightly
different performance. It doesn’t matter whether you’re designing a coffee

Op Amp Glossary
Common-Mode Voltage Range (CMVR)
Open- Loop Gain (AVO)
Also known as input voltage range, CMVR is the allowable input voltage
The ratio of the output voltage to the input offset voltage between the two
range at both inputs before clipping or excessive nonlinearity is seen at the input pins. The result is expressed in dB. Gain is usually specified only at
output.
dc (AO), but for many applications, such as high speed amplifiers for video
and RF, the frequency dependence of gain is also important. For this reason
the open loop gain and phase response is published for each amplifier.
Common-Mode Rejection Ratio (CMRR)
The ratio of the common-mode voltage range (CMVR) to the change in the
input offset voltage (ΔVoOS) over this range. The result is expressed in dB.
CMRR (dB) = 20log (CMVR/ΔVOS)
Operating Supply Voltage Range
The supply voltage range that can be applied to an amplifier for which
it operates within specifications. Many applications implement op amp
circuits with balanced dual supplies, while other applications for energy
conservation or other reasons, use single-supply. For example, battery
power in automotive and marine equipment provides only a single polarity.
Even line-powered equipment, such as computers, may have only a single-
polarity built-in supply, furnishing +5 V or +12 V dc for the system, or
often as low as 1.8 V, with newer applications going even lower.
Full Power Bandwidth
The maximum frequency measured at unity gain for which the rated
output voltage can be obtained for a sinusoidal signal at rated load without
distortion due to slew rate limiting.
Gain Bandwidth Product (GBW)
The product of open-loop gain and bandwidth at a specific frequency.
Power Supply Rejection Ratio (PSRR)
The ratio of the change in power supply voltage to the change in input
offset voltage. The result is expressed in dB. PSRR = 20log (ΔVSY/ΔVOS)
Input Bias Current (IB)
The current at the input terminals.
Settling Time
Input Bias Current Drift
The amount of time required for an amplifier to settle to some predetermined
level of accuracy or percentage of output voltage after the application of a
step input.
The proportional change in input bias current vs. temperature over a
specified range of temperature.
Input Offset Current
The difference between the two input currents.
Slew Rate
The maximum rate of change of output voltage under large signal
condition. The result is usually expressed in V/µs.
Input Offset Current Drift
The ratio of input offset current change over a specified temperature range,
with the output held a constant voltage.
Supply Current
The current required from the supply voltage to operate the amplifier with
no load.
Input Offset Voltage Drift (TCVOS)
The ratio of change in input offset voltage to a change in temperature.
Small Signal Unity Gain Frequency
The frequency at which the open-loop gain is unity or 0 dB. This applies
only to signals under 200 mV. Due to slew rate limiting, it is not possible to
obtain large output voltage swings at high frequencies.
Offset Voltage (VOS)
The differential voltage needed across the op amp input terminals to obtain
zero output voltage. Offset voltage values range varies by process and
design technology:
•ꢀAuto-Zero Op Amps: <1 µV
•ꢀPrecision Op Amps: 50 µV to 500 µV
•ꢀBest Bipolar Op Amps: 10 µV to 25 µV
•ꢀBest JFET Iput Op Amps: 100 µV to 1000 µV
•ꢀBest Bipolar High Speed Op Amps: 100 µV to 2000 µV
•ꢀUntrimmed CMOS Op Amps: >2 mV
•ꢀDigiTrim® CMOS Op Amps: <100 µV to 1000 µV

Amplifier Design Technology
Clamp Amplifiers
Quad Core (H Bridge)
Clamp amplifiers allow the designer to specify a high (VCH) and low (VCL)
output clamp voltage so the output signal will clamp at the specified
levels. Analog Devices’ unique CLAMPIN™ input clamp architecture offers
significant improvement in clamp performance compared to traditional
output clamping devices, minimizing clamp error and distortion in the
clamp region.
Analog Devices has patented the quad core architecture, which supplies
current on-demand to charge and discharge the internal dominant pole
capacitor, while allowing the quiescent current to be small. This patented
architecture enables amplifiers to provide high slew rates with low
distortion at low supply currents.
Overvoltage Protection (OVP) Amplifiers
Common-Mode Linearized Amplifiers
An OVP amplifier is the most robust solution to protect the amplifier and
entire circuitry from outside the rail input voltages due to manufacturing
shorts, power supply timing, or human error. OVP is able to protect real
estate from various unexpected errors, which in turns save time and
money. OVP amplifiers require no external circuitry to provide protection.
Increasing the linear input range of the input stage optimizes operational
amplifier large signal distortion. This can be accomplished through the
use of architectures such as degenerated differential structures and
class AB input stages, both of which increase noise and lower precision.
An alternate method is to linearize using a common-mode structure
whose noise is rejected by the inherent differential nature of the input
stage while also maintaining such precision metrics as CMRR, PSRR, and
VOS. Analog Devices has numerous new amplifiers that now feature this
new technology and has patented the common-mode linearized input
architecture.
Zero-Drift Amplifiers
Zero-drift amplifiers dynamically correct the offset voltage to achieve
nanovolt-level offsets and extremely low offset drifts due to time and
temperature. The 1/f noise, seen as a dc error, is also removed. Zero-drift
amplifiers provide many benefits to designers, as temperature drift and
1/f noise, always nuisances in the system, are otherwise very difficult to
eliminate. In addition, zero-drift amplifiers have higher open-loop gain,
power supply rejection, and common-mode rejection as compared to
standard amplifiers; and their overall output error is less than that
obtained by a standard precision amplifier in the same configuration.
Current Feedback Amplifiers
Current feedback amplifiers are primarily used in applications that require
very high speed operation, large slew rates, and low distortion. The
fundamental concept is based on the fact that, in bipolar transistor circuits,
currents can be switched faster than voltages, all other things being equal.
Unlike voltage feedback amplifiers (VFB), CFB amplifiers do not have
balanced inputs. Instead, the noninverting input is high impedance, and
the inverting input is low impedance. The open-loop gain of the CFB is
measured in units of V (transimpedance gain) rather than V/V as for VFB
amplifiers. Also, the value of the feedback resistor plays a direct role in the
CFB’s stability. Therefore, adhering to the recommended feedback resistor
suggested in the data sheet is highly recommended.
Zero Input Crossover Distortion (ZCO) Amplifiers
Traditional rail-to-rail input amplifiers have an input stage that comprises
two differential pairs, a p-type and an n-type. During the transition of the
input common-mode voltage from the lower to the higher supply voltage,
one of the differential pairs turns off and the other turns on. This transition
causes crossover distortion. Zero input crossover distortion (ZCO) amplifiers
solve this problem by integrating an on-chip charge pump. The charge
pump increases the internal supply voltage, thus providing more headroom
to the input stage. This allows the input stage to handle a wider range of
input voltages (rail to rail) without using a second differential pair. As a
result, crossover distortion is avoided.
Differential Amplifiers
Differential amplifiers allow the process of single-ended input to
complementary differential outputs or differential inputs to differential
outputs. These amplifiers feature two separate feedback loops to control
the differential and common-mode output voltages. Analog Devices’
differential amplifiers are configured with a VOCM pin, which can be easily
adjusted for setting output common-mode voltage. This provides a
convenient solution when interfacing with analog-to-digital converters
(ADCs). ADI also offers a series of differential receiver products that
convert differential input signals to single-ended output.

Amplifier Process and Trimming Technology
JFET Input Amplifiers
Process Technology
Bipolar
JFET input amplifiers have the advantage over bipolar devices by having
an extremely high input impedance along with low noise performance,
making them very useful in amplifier circuits using very small signals
such as high source impedance sensors and photodiodes. A typical JFET
has a voltage noise slightly larger than a BJT, but its current noise is
significantly lower.
Bipolar technology delivers the best overall performance amplifiers. It
offers high output current drive, high voltage operation, and low noise.
Extremely Fast Complementary Bipolar (XFCB 1.5)
Analog Device’s XFCB 1.5 technology is a suite of advanced bipolar
fabrication processes that features dielectric isolation, high speed
complementary NPNs and PNPs with 3 GHz to 8 GHz frequency transition,
precision capacitors, and low temperature-coefficient thin film resistors
that can be trimmed at the wafer level. Dielectric isolation allows much
tighter spacing between components and removes the possibility of latch-
up. Nonlinear device-to-substrate capacitance that limits device speed and
distortion performance is eliminated. XFCB1.5 has supply voltage options
from 8 V to 26 V; this allows the selection of the fastest devices possible
for the required input and output voltage ranges.
Trimming Technology
Laser Trim
When extremely fine adjustment is required, laser trimming is most
effective. By controlling the path and speed of the laser beam, the
resistor’s value can be adjusted to very precise values. Analog Devices
pioneered the use of thin film resistors and laser trimming and uses
this technology extensively in precision amplifiers, references,
and converters.
XFCB3
Zener Zapping
Analog Devices’ XFCB3 technology features full dielectric isolation, silicon-
germanium hetero-junction NPNs with frequency transition up to 50 GHz
and double-poly PNPs with frequency transition up to 18 GHz, precision
capacitors, and low temperature coefficient thin film resistors. Minimum
feature size is a factor of three less than XFCB1.5. This process family has
enabled a new generation of high speed, ultralow distortion differential
amplifiers and op amps.
With each zap removing a predefined resistance value, the nature of
the trims is discrete. It is most cost-effective for fairly large geometry
processes. Analog Devices pioneered the use of Zener-zap trimming and
created the industry standard OP07 precision amplifier.
DigiTrim
Analog Devices’ DigiTrim™ is a patented in-package trimming process that
delivers guaranteed high accuracy. This in-package process technology
eliminates the need for laser trimming during manufacturing and
minimizes the input offset of operational amplifiers.
36 V iPolar
Analog Devices’ iPolar™ 36 V precision bipolar process is highly optimized
for linear circuits, yielding new levels of performance, size, and value. The
iPolar process combines the advantages of precision bipolar and JFET
with lateral dielectric isolation and modular processing. The transistors
on iPolar devices have been redesigned from the ground up and are
optimized for speed, noise, matching, linearity, and stability at lower power
levels. This enables greater signal chain integration without compromising
performance.
16 V iCMOS Amplifiers
Analog Devices’ iCMOS® industrial manufacturing process technology
combines submicron CMOS with high voltage complementary bipolar
technologies. It enables the development of a wide range of high
performance analog ICs capable of 30 V operation in a smaller footprint.
Unlike analog ICs using conventional CMOS processes, iCMOS components
can tolerate high supply voltages, while providing increased performance,
dramatically lower power consumption, and reduced package size. iCMOS
components tolerate high voltages (greater than 6 V regular CMOS amps)
while employing digital design techniques such as auto-zero and DigiTrim
technologies.

Zero Input Crossover Distortion (ZCO) Amplifiers
ADA4505-2: 10 µA, Rail-to-Rail I/O, Zero Input Crossover Distortion Amplifier
The ADA4505-x family solves the crossover distortion problem by using an on-chip charge pump to power the input differential pair. The charge pump
creates a supply voltage higher than the voltage of the battery, allowing the input stage to handle a wide range of input signal voltages without using a
second differential pair. With this solution, the input voltage can vary from one supply extreme to the other with no distortion, thereby restoring the full
common-mode dynamic range of the op amp.

Overvoltage Protection (OVP) Amplifiers
ADA4091-2/ADA4091-4: Micropower, OVP, Rail-to-Rail Input/Output Operational Amplifier
The ADA4091-2 dual and ADA4091-4 quad are micropower, single-supply, 1.2 MHz bandwidth amplifiers featuring rail-to-rail inputs and outputs. They are
guaranteed to operate from a +2.7 V to +30 V single supply, as well as from ±1.35 V to ±15 V dual supplies. The ADA4091 family features a unique input
stage that allows the input voltage to exceed either supply safely without any phase reversal or latch-up; this is called overvoltage protection, or OVP.

Precision Amplifiers (Bandwidth < 50 MHz)
Ultralow Offset Voltage (VOS ≤ 250 µV Max) Amplifiers
AD8597/AD8599: Ultralow Distortion, Ultralow Noise Operational Amplifier
The AD8597 (single) and AD8599 (dual) are very low noise, low distortion operational amplifiers ideal for use as preamplifiers. The low noise of 1.1 nV/√Hz
and low harmonic distortion of −120 dB (or better) at audio bandwidths give the devices the wide dynamic range necessary for preamplifiers in audio,
medical, and instrumentation applications. The excellent slew rate of 14 V/µs and 10 MHz gain bandwidth make them highly suitable for medical
applications. The low distortion and fast settling time make them ideal for buffering of high resolution data converters.

Precision Amplifiers (VOS < 1 mV, Bandwidth < 50 MHz)
Low Offset Voltage (VOS ≤ 1 mV)
AD8657: Precision, Micropower, 18 V CMOS RRIO Op Amplifier
The AD8657 is a dual, precision, micropower, rail-to-rail input/output (RRIO) amplifier optimized for low power and wide operating supply voltage range
applications. The device operates from 2.7 V up to 18 V with a typical quiescent supply current of 18 mA and achieves low offset voltage thanks to Analog
Devices’ patented DigiTrim trimming technique. The AD8657 also has high immunity to electromagnetic interference. The combination of low supply cur-
rent, low offset voltage, very low input bias current, wide supply range, and rail-to-rail input and output makes the AD8657 ideal for current monitoring and
current loops in process and motor control applications. In addition, the precision specifications make this device well suited for dc gain and buffering of
sensor front ends or high impedance input sources in wireless or remote sensors or transmitters

Precision Amplifiers (VOS < 1 mV, Bandwidth < 50 MHz)
Rail-to-Rail Output Amplifiers
AD8641: Low Power, Rail-to-Rail Output Precision JFET Amplifier
The AD8641/AD8642/AD8643 are low power, precision JFET input amplifiers featuring extremely low input bias current and rail-to-rail output. The ability
to swing nearly rail-to-rail at the input and rail-to-rail at the output enables designers to buffer CMOS DACs, ASICs, and other wide output swing devices
in single-supply systems. The outputs remain stable with capacitive loads of more than 500 pF.

Precision Amplifiers (VOS < 1 mV, Bandwidth < 50 MHz)
Rail-to-Rail Input/Output Amplifiers
AD8656: Low power, Precision RRIO CMOS Amplifier
The AD8656 provides low noise (2.7 nV/√Hz @ 10 kHz), low THD + N (0.0007%), and high precision performance (250 µV max over VCM) to low voltage
applications. The ability to swing rail-to-rail at the input and output enables designers to buffer analog-to-digital converters (ADCs) and other wide dynamic
range devices in single-supply systems.

High Speed Amplifiers (BW > 50 MHz)
Low Cost Amplifiers
ADA4891: Low Cost CMOS, High Speed, Rail-to-Rail Amplifiers
The ADA4891-1 (single), ADA4891-2 (dual), ADA4891-3 (triple), and ADA4891-4 (quad) are CMOS high speed amplifiers that offer high performance at
a low cost. The amplifiers feature true single-supply capability, with an input voltage range that extends 300 mV below the negative rail. The rail-to-rail
output stage enables the output to swing within 50 mV of each rail, enabling maximum dynamic range. The ADA4891 family of amplifiers is ideal for
imaging applications, such as consumer video, CCD buffers, and contact image sensor buffers. Low distortion and fast settling time also make them ideal
for active filter applications.

High Output Current Amplifiers
AD8397: Rail-to-Rail, High Output Current Amplifier
The AD8397 has two voltage feedback operational amplifiers capable of driving heavy loads with excellent linearity. The common-emitter, rail-to-rail output
stage surpasses the output voltage capability of typical emitter-follower output stages and can swing to within 0.5 V of either rail while driving a 25 Ω load.
The low distortion, high output current, and wide output dynamic range make the AD8397 ideal for applications that require a large signal swing into a
heavy load.

Clamp Amplifiers
AD8036: Low Distortion, Wide Bandwidth Voltage Feedback Clamp Amps
The AD8036 and AD8037 are wide bandwidth, low distortion clamping amplifiers. The AD8036 is unity-gain stable. The AD8037 is stable at a gain of two or
greater. These devices allow the designer to specify a high (VCH) and low (VCL) output clamp voltage. The output signal will clamp at these specified levels.
Utilizing a unique CLAMPIN™ input clamp architecture, the AD8036 and AD8037 offer a 10× improvement in clamp performance compared to traditional
output clamping devices. In particular, clamp error is typically 3 mV or less and distortion in the clamp region is minimized. This product can be used as a
classical op amp or a clamp amplifier where a high and low output voltage are specified.

Amplifier Packaging
ADI offers a wide variety of plastic packages from through-hole to surface-mount applications. Many of these plastic packages provide cost-
effective solutions to achieving greater board density (surface-mount packages) and high performance. Plastic packages are extensively used
in many of today’s applications.
Analog Devices offers molded plastic packages and the primary materials are a leadframe, die attach material, bond wire, mold compound,
and a Pb-free finish. In order to provide plastic package solutions that do not sacrifice reliability or functionality, Analog Devices continues
to improve on the materials used, whether focusing on leadframe composition for increased thermal conductivity, low stress mold compound
used for large die applications, or low moisture absorption mold compounds for improved reliability.
Improvements in the small surface-mount packages include the introduction of the devices offered in small body size packages. The following
table provides information on smaller plastic packages offered by Analog Devices.
