Description

The OP177 is an electronic component, specifically an Instrumentation OpAmp. It is known for its high precision performance, making it one of the most accurate op amps in the market. With a maximum offset voltage of only 25 μV at room temperature, the OP177 eliminates the need for external voltage adjustment and provides increased system accuracy over temperature. It maintains an open-loop gain of 12 V/μV over a full ±10 V output range, ensuring accurate performance even in high closed-loop gain applications. The OP177 also boasts exceptional common-mode rejection ratio (CMRR) of 130 dB minimum, power supply rejection ratio (PSRR) of 120 dB minimum, and a maximum supply current of 2 mA. It is designed to fit industry-standard precision op amp sockets.
