Product details
Overview
AMP02FSZ-RL from Analog Devices is a high-accuracy instrumentation amplifier in 16-lead SOIC package, featuring laser-trimmed input offset voltage ≤200 µV, output offset voltage ≤8 mV, and gain accuracy ≤0.7% at G = 1000. It supports gain range 1–10,000 via single external resistor and delivers 200 kHz bandwidth at G = 1000, making it suitable for precision strain gage and thermocouple signal conditioning in industrial data acquisition systems.
For engineers reviewing the AMP02FSZ-RL datasheet, AMP02FSZ-RL pinout, AMP02FSZ-RL application, or AMP02FSZ-RL equivalent, key selection considerations include its ±4.5 V to ±18 V dual supply operation, 115 dB minimum CMR at G = 1000, input overvoltage protection to ±60 V beyond rails, and reference pin for dc level shifting-critical for low-drift sensor front-ends requiring stable offset control.
Technical Context
The AMP02FSZ-RL implements a triple-op-amp topology with transimpedance input stages and unity-gain differential output stage, enabling consistent bandwidth across gain settings (1200 kHz at G = 1, 200 kHz at G = 1000). Its internal thin-film resistor network ensures gain temperature coefficient ≤50 ppm/°C independent of external RG.
Laser trimming targets input offset voltage ≤200 µV and output offset voltage ≤8 mV at 25°C, while input bias current remains ≤20 nA and common-mode input range extends to ±11 V-guaranteed by CMR testing-not limited by absolute rail voltage.
Key Specifications

|---|---|
| Input Offset Voltage | ≤200 µV max at 25°C - sets baseline error floor for low-level differential signals like thermocouples |
| Gain Accuracy | ≤0.7% max at G = 1000 - enables calibrated measurement without per-unit gain trimming |
| Common-Mode Rejection | ≥110 dB at G = 1000, ±11 V CM - rejects noise from long sensor leads in noisy industrial environments |
| Small-Signal Bandwidth | 200 kHz at G = 1000 - supports fast step response in dynamic strain monitoring |
| Slew Rate | ≥4 V/µs - prevents distortion on transient signals up to ~100 kHz full-power bandwidth |
| Supply Voltage Range | ±4.5 V to ±18 V - accommodates standard ±5 V, ±12 V, and ±15 V industrial power rails |
| Input Overvoltage Protection | ±60 V beyond either supply rail - survives transducer disconnect events or ESD-induced transients without damage |
Pinout & Package
AMP02FSZ-RL is housed in a 16-lead SOIC (Wide Body) package with exposed pad thermal performance (θJA = 92°C/W, θJC = 27°C/W). Pin 1 is index-marked; pins labeled NC are internally disconnected and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 6, 8, 10–12, 14, 15 | No Connect (NC) | Internally open; must be left floating or tied to ground only if required for mechanical stability |
| 3 | RG1 | One terminal of external gain-setting resistor; connects to internal 25 kΩ resistor node |
| 5 | –IN | Inverting input of first-stage transimpedance amplifier; high-impedance differential input node |
| 7 | +IN | Non-inverting input of first-stage transimpedance amplifier; high-impedance differential input node |
| 9 | SENSE | Output feedback return point; internally connected to OUT in SOIC version - must be shorted to OUT |
| 13 | V– | Negative supply rail connection; also substrate tie point for die-level ESD protection |
| 16 | V+ | Positive supply rail connection; supplies both input and output stages |
| 11 | REFERENCE | Output DC reference level input; sets output common-mode voltage - critical for ADC interfacing |
| 12 | OUT | Differential output buffer stage; drives 1 kΩ load to ±12 V swing at 25°C |
Key Features
| Feature | Design Value |
|---|---|
| Single-resistor gain programming | Gain set from 1 to 10,000 using one external metal-film resistor (RG = 50 kΩ/(G−1)), eliminating matched resistor networks |
| Laser-trimmed thin-film resistors | Internal resistor matching holds gain tempco ≤50 ppm/°C and CMR ≥110 dB across –40°C to +85°C |
| Input overvoltage protection | Withstands ±60 V differential input beyond supply rails - protects against transducer fault conditions without external clamps |
| Reference pin for level shifting | Allows output DC bias to be set independently of supply rails - enables single-supply ADC interfacing with bipolar input signals |
| Triple-op-amp architecture | Maintains 200 kHz bandwidth at G = 1000 and 1200 kHz at G = 1 - preserves signal fidelity across wide gain range without compensation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar instrumentation amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8421ARZ | Lower input offset (25 µV max), higher CMR (130 dB), but requires dual external resistors for gain setting | Better for ultra-low-drift medical or metrology use; less suited for cost-sensitive industrial designs needing single-RG simplicity | Choose AD8421ARZ when sub-50 µV offset and >125 dB CMR are mandatory; retain AMP02FSZ-RL for legacy designs or where single-RG layout advantage outweighs offset spec |
| INA128UA | Higher input offset (125 µV max), lower bandwidth (1200 kHz at G = 1 only), no SENSE pin or internal overvoltage protection | Targeted at general-purpose industrial signal conditioning where ±60 V input protection is not required | Select INA128UA for simpler PCB routing and lower cost where input fault tolerance is managed externally; AMP02FSZ-RL preferred when robustness to field faults is critical |
Compared with AD8421ARZ and INA128UA, AMP02FSZ-RL uniquely balances single-resistor programmability, ±60 V input overvoltage tolerance, and 0.7% gain accuracy at G = 1000 - making it optimal for ruggedized industrial DAQ where design simplicity and fault resilience are prioritized over ultra-low offset.

FAQ
What is the maximum gain achievable with AMP02FSZ-RL, and how is it set?
The AMP02FSZ-RL supports a gain range of 1 to 10,000, set by a single external resistor RG connected between pins 3 (RG1) and 8 (RG2). The gain equation is G = (50 kΩ / RG) + 1. For unity gain, no external resistor is needed. This single-resistor method simplifies layout and reduces component count compared to dual-resistor IAs like the AD8421ARZ.
Does AMP02FSZ-RL require external input protection diodes given its ±60 V overvoltage rating?
No, AMP02FSZ-RL does not require external input protection diodes. Its internal protection circuitry limits input current to ±4 mA during ±60 V differential overvoltage events with power off, and ±2.5 mA with power on - sufficient for most industrial transducer fault conditions. External diodes would degrade CMR and add noise.
How should the SENSE and REFERENCE pins be connected in AMP02FSZ-RL?
For AMP02FSZ-RL (16-lead SOIC), the SENSE pin (pin 9) must be connected directly to the OUT pin (pin 12) as specified in the datasheet. The REFERENCE pin (pin 11) sets the output common-mode voltage and may be tied to analog ground, a precision reference, or an offset-adjust voltage - enabling level shifting for single-supply ADC interfacing.
What is the guaranteed common-mode rejection ratio (CMR) of AMP02FSZ-RL over temperature?
The AMP02FSZ-RL guarantees ≥110 dB CMR at G = 1000 and VCM = ±11 V across the full operating temperature range of –40°C to +85°C. This is achieved through laser trimming of internal thin-film resistors and is validated per the datasheet's "ELECTRICAL CHARACTERISTICS" table under "Common-Mode Rejection".
Can AMP02FSZ-RL operate from a single supply, and what are the limitations?
AMP02FSZ-RL is designed for dual-supply operation (±4.5 V to ±18 V) and does not support true single-supply operation. While the REFERENCE pin allows output level shifting, the input common-mode range remains centered around midsupply and cannot extend to the negative rail. Attempting single-supply use risks clipping and degraded CMR; dual supplies are mandatory for specified performance.
