Product details
Overview
AMP02FPZ from Analog Devices is a high-accuracy instrumentation amplifier in an 8-lead plastic DIP package, designed for precision differential signal conditioning. It features laser-trimmed input offset voltage ≤200 µV (max at 25°C), output offset voltage ≤8 mV (max), gain range of 1–10,000 set by a single external resistor, and input overvoltage protection to ±60 V beyond supply rails. It is used in strain gage, thermocouple, and RTD amplifier circuits requiring stable dc accuracy and high common-mode rejection.
For engineers reviewing the AMP02FPZ datasheet, AMP02FPZ pinout, AMP02FPZ application, or AMP02FPZ equivalent, key selection considerations include its guaranteed 110 dB min CMR at G=1000, 200 kHz bandwidth at G=1000, 4 V/µs slew rate, ±4.5 V to ±18 V dual-supply operation, and internal sense-to-output connection in the PDIP variant - all critical for low-drift sensor front-end designs.
Technical Context
The AMP02FPZ implements a triple-op-amp instrumentation topology with transimpedance input stages and a unity-gain differential output stage. Its laser-trimmed thin-film resistors achieve gain temperature coefficient ≤50 ppm/°C and input offset drift ≤2 µV/°C over –40°C to +85°C.
It integrates input protection circuitry limiting current to ±4 mA during power-off 60 V differential overloads, and provides dedicated REFERENCE and SENSE pins: REFERENCE sets output DC level (50 kΩ input resistance), while SENSE is internally tied to OUT in the 8-lead PDIP package (AMP02FPZ), eliminating external feedback routing.

Pinout & Package
AMP02FPZ is packaged in an 8-lead plastic dual-in-line package (PDIP, N-8), with 0.300-inch width and JEDEC MO-095AA compliance. Pin 1 is index-marked; pins are spaced 0.100 inch (2.54 mm) on-center.

Applications
| Strain Gage Amplifier | Thermocouple Amplifier |
|---|---|
Use Scenario: Amplifying mV-level Wheatstone bridge outputs from metal foil or semiconductor strain gages in load cells and pressure sensors. IC Role / Device Role / Timing Role: Precision instrumentation amplifier providing high CMR, low offset drift, and stable gain to resolve microstrain-level changes. Use Value: Input overvoltage protection prevents damage during mechanical shock-induced bridge imbalance; 200 µV max VIOS ensures <0.1% error at 200 mV full-scale output. |
Use Scenario: Conditioning low-amplitude, high-impedance thermocouple outputs (e.g., Type K, J) in industrial temperature monitoring systems. IC Role / Device Role / Timing Role: Differential front-end amplifier rejecting common-mode noise from furnace EMI and ground loops. Use Value: 110 dB CMR at G=1000 suppresses 60 Hz pickup; 0.5 µV/°C typical TCVIOS minimizes thermal drift errors across ambient temperature swings. |
| RTD Amplifier | Medical Instrumentation Front-End |
Use Scenario: Exciting and measuring 3-wire or 4-wire Pt100/Pt1000 RTDs in precision temperature transmitters. IC Role / Device Role / Timing Role: Programmable-gain instrumentation amplifier with reference pin enabling ratiometric excitation and offset nulling. Use Value: Single-resistor gain setting (G=10–100) simplifies calibration; REFERENCE pin allows direct connection to excitation source for true ratiometric operation. |
Use Scenario: Biopotential signal acquisition in ECG, EEG, or EMG systems where electrode contact impedance varies widely. IC Role / Device Role / Timing Role: High-input-impedance (10 GΩ differential), low-noise instrumentation amplifier rejecting mains interference and motion artifacts. Use Value: Input protection tolerates defibrillation pulses; 9 nV/√Hz input-referred noise at G=1000 preserves SNR for µV-level neural signals. |
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 max gain (1–1000), higher input bias current (1 nA typ vs. 10 nA max), no integrated input overvoltage protection | Better suited for lower-gain, higher-speed applications; lacks ±60 V fault tolerance required in industrial sensor nodes | Select AD620ARZ only when gain ≤1000 suffices and external protection can be added; AMP02FPZ preferred for ruggedized field deployments |
| INA128U | Higher input offset drift (0.3 µV/°C typ vs. 2 µV/°C max), wider supply range (±2.25 V to ±18 V), no SENSE pin | More flexible for low-voltage battery-powered systems but less stable over temperature in precision lab equipment | Choose INA128U for portable instrumentation with tight supply constraints; AMP02FPZ delivers superior long-term dc stability in fixed-installation systems |
Compared with AD620ARZ and INA128U, AMP02FPZ uniquely combines ±60 V input fault tolerance, internal SENSE-to-OUT connection for simplified PDIP layout, and guaranteed 110 dB CMR at G=1000 - making it optimal for industrial sensor signal chains demanding robustness and metrological accuracy.

FAQ
What is the maximum gain achievable with AMP02FPZ, and how is it set?
The AMP02FPZ supports a voltage 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 (G = 1), no external resistor is required - pins 1 and 8 are left unconnected. This configuration is validated in the AMP02FPZ datasheet's Figure 1 and Ordering Guide.
Does AMP02FPZ require external components for basic operation, and what are the minimum connections?
Yes - AMP02FPZ requires at minimum: dual supplies (V+ and V–), grounded REFERENCE pin (or connected to desired dc bias), and proper decoupling capacitors (0.1 µF ceramic + 10 µF tantalum per supply). For gain >1, one external resistor RG is mandatory. The SENSE pin is internally connected to OUT in the 8-lead PDIP package (AMP02FPZ), so no external feedback is needed - unlike SOIC variants.
How does the input overvoltage protection in AMP02FPZ function, and what fault conditions does it cover?
The AMP02FPZ includes on-chip protection that limits input current to ±4 mA during power-off 60 V differential overloads, and ±2.5 mA with power applied - per Figure 5 in the datasheet. It protects against transducer failures, accidental wiring to higher voltages, and hot-plug events. This eliminates the need for external series resistors or clamping diodes in most industrial sensor interfaces.
What is the significance of the SENSE pin in AMP02FPZ, and how is it configured in the PDIP package?
In the AMP02FPZ (8-lead PDIP), the SENSE pin is not brought out externally - it is internally connected to the OUT pin. This configuration is explicitly stated in the "GENERAL DESCRIPTION" section and confirmed in Figure 1 ("In the 8-lead package, sense is internally connected to the output"). Therefore, no external SENSE connection is required or possible for AMP02FPZ, simplifying layout versus SOIC versions like AMP02FS.
Can AMP02FPZ operate from a single supply, and what are the limitations?
No - AMP02FPZ is specified only for dual-supply operation (±4.5 V to ±18 V). Its input common-mode range extends to ±11 V, and output swing reaches ±12 V with RL = 1 kΩ, both referenced to ground. Single-supply operation would violate absolute maximum ratings and degrade CMR, offset, and bandwidth. For single-supply applications, consider alternatives such as AD8421 or INA333.
