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 VOS drift and rapid stabilization time,
combined with only 50 mW of power consumption, are
significant improvements over previous designs. These
characteristics, plus the exceptional TCVOS of 0.3 μV/°C
maximum and the low VOS of 25 μV maximum, eliminates the

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.
