Product details
Overview
AMP02EPZ from Analog Devices is a high-accuracy instrumentation amplifier in an 8-lead PDIP package, designed for precision differential signal conditioning. It features laser-trimmed input offset voltage ≤100 µV, gain accuracy ≤0.5% at G=1000, and input overvoltage protection up to ±60 V beyond supply rails. Its 200 kHz bandwidth at G=1000 and 4 V/µs slew rate support fast data acquisition in strain gage and thermocouple measurement systems.
For engineers reviewing the AMP02EPZ datasheet, AMP02EPZ pinout, AMP02EPZ application, or AMP02EPZ equivalent, key selection considerations include its single-resistor gain setting (G = 1–10,000), reference-pin-based output level shifting, internal sense-to-output connection, and guaranteed performance across –40°C to +85°C.
Technical Context
The AMP02EPZ implements a triple-op-amp instrumentation topology with transimpedance input stages and a unity-gain differential output stage. Laser trimming of internal thin-film resistors achieves <100 µV input offset and <50 ppm/°C gain temperature coefficient.
Its input protection network limits current to ±4 mA during 60 V differential overvoltage events with power off, and ±2.5 mA with power on. The reference pin enables dc level shifting or offset correction, while the internally connected sense terminal ensures stable closed-loop operation without external feedback routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ≤100 µV max at 25°C - ensures minimal baseline error in low-level sensor signals like thermocouples. |
| Gain Accuracy | ≤0.5% at G=1000 - enables precise scaling without post-calibration in programmable gain systems. |
| CMR | ≥115 dB at G=1000 - rejects noise common to both inputs, critical in noisy industrial environments. |
| Small-Signal Bandwidth | 200 kHz at G=1000 - supports accurate amplification of dynamic sensor outputs up to ~160 kHz. |
| Slew Rate | ≥4 V/µs - handles fast transient inputs without distortion in data acquisition front ends. |
| Input Overvoltage Protection | ±60 V beyond rails - eliminates need for external clamping diodes in ruggedized sensor interfaces. |
| Supply Current | 6 mA max - enables use in low-power precision systems without thermal derating concerns. |
Pinout & Package
AMP02EPZ is housed in an 8-lead plastic dual-in-line package (PDIP), compliant with JEDEC MO-095AA. Pin 1 is marked with a notch or dot; pins are numbered counterclockwise from top-left when viewed from top.

| 3 (+IN) | Non-inverting input | Differential input node; accepts positive polarity of sensor bridge or transducer output. |
| 4 (V–) | Negative supply rail | Connects to negative analog supply (–4.5 V to –18 V); substrate tie point for die. |
| 5 (REFERENCE) | Output reference level | Sets output DC bias; connect to ground or external offset voltage for level shifting. |
| 6 (OUT) | Amplified output | Delivers gain-scaled differential signal referenced to REF pin; drives 1 kΩ load to ±12 V. |
| 7 (V+) | Positive supply rail | Connects to positive analog supply (+4.5 V to +18 V); powers all internal amplifier stages. |

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 drift (0.3 µV/°C typ vs. 2 µV/°C max), but no integrated overvoltage protection; requires external RG. | Better for ultra-stable lab-grade measurements; unsuitable for unconditioned field sensor inputs. | Select AD620ARZ when long-term drift dominates error budget and input transients are absent. |
| INA128U | Higher supply current (1.3 mA vs. 6 mA), lower bandwidth (1.3 MHz at G=1), no reference pin; includes internal RG for fixed gains. | Optimized for portable battery-powered devices; lacks level-shifting flexibility for multi-rail systems. | Select INA128U when board space and power are constrained, and gain is fixed at 5–10,000. |
Compared with AMP02EPZ, AD620ARZ offers superior drift performance but requires external protection circuitry, while INA128U reduces component count at the expense of bandwidth and output referencing capability-making AMP02EPZ optimal for rugged, flexible, high-fidelity sensor interfaces.

FAQ
What is the maximum gain achievable with AMP02EPZ, and how is it set?
The AMP02EPZ supports a gain range of 1 to 10,000, set by a single external resistor RG connected between Pins 1 (RG1) and 8 (RG2). The gain equation is G = 50 kΩ/RG + 1. For unity gain, no resistor is required. This configuration is validated in the AMP02EPZ datasheet Rev. E, Figure 1 and Applications Information section.
Does AMP02EPZ require external components for basic operation?
AMP02EPZ operates at unity gain without any external components. For gain >1, only one precision metal-film or wirewound resistor (RG) is needed between Pins 1 and 8. External bypass capacitors (e.g., 0.1 µF ceramic) on V+ and V– are recommended for supply stability, but not strictly required for functional operation per the AMP02EPZ specifications.
How does the REFERENCE pin function in AMP02EPZ?
The REFERENCE pin (Pin 5) sets the output DC level of AMP02EPZ. When grounded, the output centers around 0 V. Connecting it to a voltage source (e.g., +2.5 V) shifts the entire output swing accordingly. Its 50 kΩ input resistance means source impedance must be ≤1 Ω to avoid degrading CMR by more than 1 dB, as specified in the AMP02EPZ Applications Information section.
What is the operating temperature range for AMP02EPZ?
The AMP02EPZ is rated for continuous operation from –40°C to +85°C, as confirmed in the Ordering Guide and Absolute Maximum Ratings tables of the AMP02EPZ datasheet Rev. E. Performance parameters-including input offset voltage, CMR, and bandwidth-are guaranteed across this full industrial temperature range.
Is AMP02EPZ pin-compatible with other packages of the AMP02 family?
No. AMP02EPZ uses an 8-lead PDIP footprint (N-8), while AMP02FS uses a 16-lead SOIC (R-16) with different pin assignments-including NC pins and a dedicated SENSE pin. The PDIP and SOIC variants share functional equivalence but differ electrically and mechanically; PCB layout must match the specific package variant selected, as detailed in the Outline Dimensions section of the AMP02EPZ datasheet.
