GENERAL DESCRIPTION
The OP-77 significantly advances the state-of-the-art in preci-
sion op amps. The OP-77's outstanding gain of 10,000,000 or
more is maintained over the full :10V output range. This excep-
tional gain-linearity eliminates incorrectable system nonlineari-
ties common in previous monolithic op amps, and provides
SIMPLIFIED SCHEMATIC
superior performance in high closed-loop-gain applications.
Low initial Vos drift and rapid stabilization time, combined with
only 50mW power consumption, are significant improvements
over previous designs. These characteristics, plus the exCep-
tional TCVOS of 0.3wVf'C maximum and the low Vos of 25yV
maximum, eliminates the need for Vos adjustment and in-
creases system accuracy over temperature.
PSRR of NNN (1 10dB) and CMRR of1.0p.VN maximum virtu-
ally eliminiate errors caused by power supply drifts and com-
mon-mode signals. This combination of outstanding character-
istics makes the OP-77 ideally suited for high-resolution instru-
mentation and other tight error budget systems.
