Features and Benefits
Product DetailsThe OP77 significantly advances the state-of-the-art in precision op amps. The OP77's outstanding fgain of 10,000,000 or more is maintained over the full ±10V 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 intitial VOS drift and rapid stabilization time, combined with only 50mW power consumption, are significant imporvements over previous designs. These characteristics, plus the exceptional TCVOS and the low VOS of 25µV maximum, eliminates the need for VOS adjustment and increases system accuracy over temperature.
PSRR of 3µV/V (110dB) and CMRR of 1.0µV/V maximum virtually eliminates 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.
The OP77 is a direct or upgrade replacement for the OP07, 05, 725, or 108A op amps. 741-types can be replaced by eliminating the VOS adjust pot.
