What this part is and where it fits
The Analog Devices AMP02EPZ is a single-channel instrumentation amplifier in an 8-pin DIP package. It is designed to extract small differential signals in the presence of large common-mode voltages. The 20 µV input offset voltage and 2 nA input bias current keep DC errors low. Supply span runs from 9 V to 36 V.
Temperature grade and environment
Rated for -40°C to 85°C operating range — industrial temperature, not automotive. Suitable for outdoor telecom cabinets, factory automation panels, and instrumentation that lives in a climate-controlled room but sees cold starts. Not rated for under-hood or engine-bay deployment.
Lifecycle and sourcing posture
The AMP02EPZ carries an Active lifecycle status and is ROHS3 compliant. For dual-sourcing or a pin-compatible second source, the AD625KNZ is a functional peer — same instrumentation amplifier class, through-hole DIP, similar supply range — though its input offset is 25 µV and bandwidth is wider at 25 MHz.
