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.
