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

drift and rapid stabilization time, combined with only 50

V

OS

mW power consumption, are significant improvements over
previous designs. These characteristics, plus the exceptional

of 0.3 mV/∞C maximum and the low VOS of 25 mV maxi-

TCV

OS

mum, eliminates the need for V

adjustment and increases

OS

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 char­acteristics makes the OP77 ideally suited for high-resolution
instrumentation and other tight error budget systems.
