GENERAL DESCRIPTION
The OP77 has outstanding gain of 10,000,000 or more that is the need for VOS adjustment and increases system accuracy over maintained over the full 10 V output range. This gain-linearity temperature. eliminates incorrectable system nonlinearities common in A PSRR of 3 μV/V (110 dB) and CMRR of 1.0 μV/V maximum previous monolithic op amps and provides superior performance virtually eliminate errors caused by power supply drifts and in high closed-loop gain applications. Low initial VOS drift and common-mode signals. This combination of outstanding rapid stabilization time, combined with only 50 mW of power characteristics makes the OP77 ideally suited for high resolution consumption, are significant improvements over previous instrumentation and other tight error budget systems. designs. These characteristics, plus the TCVOS of 0.3 μV/°C maximum and the low VOS of 25 μV maximum, eliminates
