GENERAL DESCRIPTION

The OP77 has outstanding gain of 10,000,000 or more that is maintained over the full 10 V output range. This 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 50 mW of power consumption, are significant improvements over previous designs. These characteristics, plus the TCVOS of 0.3 μV/°C maximum and the low VOS of 25 μV maximum, eliminates the need for VOS adjustment and increases system accuracy over temperature.
