ADI’s OP177 are high precision operational amplifiers with an offset voltage of only 25 µV at room temperature. Voltage supplied can be either dual or single at 6 V to 36 V or ±3 V to 18 V and current consumption is a small 1.6 mA. These op amps provide chopper type performance at a lower cost, less board space, and less noise. The OP177 have a temperature range of -40°C to +85°C and comes in an 8-pin PDIP or 8-pin SOIC package.
