OP77FJZ Datasheet PDF - ADI

The OP77FJZ is an ultralow offset voltage single Operational Amplifier ideally suited for high-resolution instrumentation and other tight error budget systems. The OP77 significantly advances the state-of-the-art in precision op amps. The outstanding gain of 10000000 or more for the OP77 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 of power consumption, is significant improvements over previous designs. These characteristics, plus the exceptional TCVOS of 0.3µV/°C maximum 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.
