GENERAL DESCRIPTION

The OP77 significantly advances the state-of-the-art in precision op amps. The outstanding gain of 10,000,000 or more for the OP77 is maintained over the full 10 V output range. This exceptional gain-linearity eliminates incorrectable system nonlinearities common in previous monolithic op amps and provides superior performance in high closed-loop gain applications. Low initial V OS  drift and rapid stabilization time, combined with only 50 mW of power consumption, are significant improvements over previous designs. These characteristics, plus the exceptional TCV OS  of 0.3 μV/°C maximum and the low V OS  of 25 μV maximum, eliminates the need for V OS  adjustment and increases system accuracy over temperature.  
A PSRR of 3 μV/V (110 dB) and CMRR of 1.0 μV/V maximum virtually eliminate errors caused by power supply drifts and common-mode signals. This combination of outstanding characteristics makes the OP77 ideally suited for high resolution instrumentation and other tight error budget systems.
