GENERAL DESCRIPTION
The OP77 has outstanding gain of 10,000,000 or more that is
maintained over the full 10 V output range. This 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 TCVOS of 0.3 μV/°C
maximum and the low VOS of 25 μV maximum, eliminates

the need for VOS 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.
