GENERAL DESCRIPTION

The OP77 significantly advances the state-of-the-art in

precision op amps. The outstanding gain of 10,000,000 or more

for the OP77 is maintained over the full 10 V 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 V_OSdrift and rapid stabilization time,

combined with only 50 mW of power consumption, are

significant improvements over previous designs. These

characteristics, plus the exceptional TCV_OSof 0.3 μV/°C

maximum and the low V_OSof 25 μV maximum, eliminates the

need for V_OSadjustment and increases system accuracy over

temperature.

A PSRR of 3 μV/V (110 dB) and CMRR of 1.0 μV/V maximum

virtually eliminate errors caused by power supply drifts and

common-mode signals. This combination of outstanding

characteristics makes the OP77 ideally suited for high resolution

instrumentation and other tight error budget systems.
