Product details
Overview
AMP02EP from Analog Devices is a high-accuracy instrumentation amplifier in an 8-lead plastic DIP package, designed for precision differential signal conditioning. It achieves input offset voltage ≤100 µV, output offset voltage ≤4 mV, and gain accuracy ≤0.5% at G = 1000, with input overvoltage protection up to ±60 V beyond supply rails. It is used in strain gage, thermocouple, and RTD amplifier circuits requiring stable dc performance and high common-mode rejection.
For engineers reviewing the AMP02EP datasheet, AMP02EP pinout, AMP02EP application, or AMP02EP equivalent, key selection considerations include its laser-trimmed offset performance, single-resistor gain setting (G = 1 to 10,000), 115 dB min CMR at G = 1000, and operation across –40°C to +85°C without external compensation.
Technical Context
The AMP02EP implements a triple-op-amp topology with transimpedance input stages and a unity-gain differential output stage. Its internal thin-film resistor network enables <50 ppm/°C gain temperature coefficient and supports precise gain setting via a single external resistor (RG).
Laser trimming ensures input offset voltage ≤100 µV and output offset voltage ≤4 mV at 25°C, while input protection circuitry limits current to ±4 mA during 60 V differential overvoltage events-even with power off-enabling robust front-end sensing in industrial data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ≤100 µV max at 25°C - sets minimum resolvable differential signal at low gains |
| Output Offset Voltage | ≤4 mV max at 25°C - dominates total offset error at G ≤ 10 |
| Gain Accuracy | ≤0.5% at G = 1000 - enables calibrated measurement without per-unit trimming |
| Common-Mode Rejection | ≥115 dB at G = 1000, VCM = ±11 V - rejects line noise and ground-loop interference |
| Small-Signal Bandwidth | 200 kHz at G = 1000 - supports fast step response in data acquisition |
| Slew Rate | ≥4 V/µs - ensures fidelity for ≥10 V p-p signals at >100 kHz |
| Supply Voltage Range | ±4.5 V to ±18 V - accommodates standard bipolar rails and wide industrial supplies |
Pinout & Package
AMP02EP is housed in an 8-lead plastic dual-in-line package (PDIP) with 0.300-inch body width and through-hole mounting. Pin 1 is marked by a notch or dot; pins are numbered counterclockwise from top-left when viewed from top.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RG1) | Gain set resistor terminal 1 | Connects to one end of external RG; forms Kelvin connection with Pin 8 for precision gain setting |
| 2 (–IN) | Inverting input | Differential input node; accepts signals up to ±60 V beyond supply rails due to internal protection |
| 3 (+IN) | Non-inverting input | Differential input node; matched bias path with Pin 2 for low offset current error |
| 4 (V–) | Negative supply rail | Must be connected to system negative supply; substrate tie point for die |
| 5 (REFERENCE) | Output reference level | Defines output DC level; connect to analog ground or external offset correction source |
| 6 (OUT) | Amplified output | Delivers rail-to-rail swing (±12 V min into 1 kΩ); internally tied to SENSE in PDIP |
| 7 (V+) | Positive supply rail | Must be connected to system positive supply; decoupling required near pin |
| 8 (RG2) | Gain set resistor terminal 2 | Connects to other end of external RG; Kelvin-connected to Pin 1 to eliminate PCB trace resistance error |
Key Features
| Feature | Design Value |
|---|---|
| Single-resistor gain configuration | G = (50 kΩ / RG) + 1 - eliminates matching errors and simplifies BOM for G = 1 to 10,000 |
| Input overvoltage protection | ±60 V beyond rails with ≤±4 mA fault current - removes need for external clamps in sensor front ends |
| Laser-trimmed thin-film resistors | Gain tempco ≤50 ppm/°C - maintains calibration stability across industrial temperature range |
| High CMR with temperature stability | ≥110 dB at –40°C to +85°C, G = 1000 - preserves signal integrity in noisy plant-floor environments |
| Reference pin for level shifting | Unity-gain buffered input with ±11 V range - enables offset nulling or bipolar-to-unipolar translation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar instrumentation amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD620ARZ | Lower input offset (50 µV max), but no internal overvoltage protection; requires external clamps for ±60 V tolerance | Better dc precision in lab-grade equipment; unsuitable for unconditioned industrial sensor inputs | Select AD620ARZ only when input signals are pre-clamped and ambient noise is minimal |
| INA128P | Wider supply range (±2.25 V to ±18 V), but higher offset drift (3 µV/°C max) and lower CMR (100 dB min at G = 1000) | Preferred for battery-powered portable instruments; less stable over temperature in fixed-installation systems | Choose INA128P for low-voltage operation below ±4.5 V; avoid where long-term drift must stay <2 µV/°C |
Compared with AD620ARZ and INA128P, the AMP02EP uniquely combines ±60 V input fault tolerance, ≤100 µV offset, and ≤50 ppm/°C gain drift in a single 8-pin DIP-making it optimal for ruggedized industrial sensors where reliability trumps marginal dc improvement.

FAQ
What is the maximum gain achievable with AMP02EP and how is it set?
The AMP02EP supports a gain range of 1 to 10,000, set by a single external resistor RG using the equation G = (50 kΩ / RG) + 1. For G = 1000, RG = 50.05 Ω; for unity gain, no resistor is needed. The AMP02EP's Kelvin-connected RG pins (1 and 8) minimize PCB trace resistance effects, ensuring accurate gain even with low-value resistors.
Does AMP02EP require external input protection components?
No, the AMP02EP includes integrated input protection that limits current to ±4 mA during ±60 V differential overvoltage events-even with power off-eliminating the need for external clamping diodes or series resistors. This internal protection preserves signal integrity and reduces bill-of-materials cost in sensor interface designs using AMP02EP.
How does the REFERENCE pin function in AMP02EP circuits?
The REFERENCE pin on the AMP02EP defines the output DC level and accepts voltages from ±11 V. It is internally buffered with 50 kΩ input resistance and unity gain. In AMP02EP applications, it is commonly tied to analog ground for zero-referenced output, or driven by a DAC for programmable offset correction-enabling level-shifting without additional op amps.
What is the operating temperature range specified for AMP02EP?
AMP02EP is rated for continuous operation from –40°C to +85°C, with guaranteed performance including input offset voltage ≤100 µV, output offset voltage ≤4 mV, and common-mode rejection ≥110 dB at G = 1000 across this full range. This makes AMP02EP suitable for deployment in industrial control cabinets, outdoor sensor nodes, and automotive under-hood environments.
Can AMP02EP be used in SOIC packages, or is PDIP the only option?
The AMP02EP is exclusively offered in the 8-lead plastic DIP (PDIP) package, as confirmed by the Analog Devices ordering guide. Other variants like AMP02FS use 16-lead SOIC, but AMP02EP itself is not available in SOIC. Designers requiring surface-mount assembly must select AMP02FS or redesign for through-hole placement when using AMP02EP.
