GENERAL DESCRIPTION

The OP77 significantly advances the state-of-the-art in precision

op amps. The OP77’s outstanding gain of 10,000,000 or more

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

mW power consumption, are significant improvements over

previous designs. These characteristics, plus the exceptional

system accuracy over temperature.

PSRR of 3

mV/V (110 dB) and CMRR of 1.0 mV/V maximum

virtually eliminate errors caused by power supply drifts and

common-mode signals. This combination of outstanding char-

acteristics makes the OP77 ideally suited for high-resolution

instrumentation and other tight error budget systems.
