Product Descriptions

The OP-77 significantly advances the state-of-the-art in precision op amps. The OP-77's outstanding gain 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 initial Vos drift and rapid stabilization time, combined with only 50mW power consumption, are significant improvements over previous designs. These characteristics, plus the exceptional TCVos of 0.3uV/°C maximum and the low Vos of 25uVmaximum, eliminates the need for Vos adjustment and in-creases system accuracy over temperature.

PSRR of 3uV/V (110dB) and CMRR of 1.0uV/V maximum virtually eliminiate errors caused by power supply drifts and com-mon-mode signals. This combination of outstanding characteristics makes the OP-77 ideally suited for high-resolution instrumentation and other tight error budget systems.
