The device provides 100uV typical offset voltage and 0.1uV\/\u00b0C drift using a BiCMOS process without chopper stabilization, avoiding clock-feedthrough noise. The rail-to-rail output stage maximizes dynamic range in single-supply and low-voltage applications. The input common-mode range extends to the negative rail. The GPZ suffix indicates the 8-pin PDIP package, which is ideal for prototyping, socket-based systems, and through-hole PCB assembly where rework and field service are requirements. All electrical specifications are identical to the OP295GSZ in the SOIC-14 surface-mount package.","working_principle":"Identical to the OP295GSZ. The GPZ suffix only denotes the 8-pin PDIP through-hole package. See OP295GSZ entry for complete working principle details.","pin_description":"
