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.
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.
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.
