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 V
OS
drift and
rapid stabilization time, combined with only 50 mW of power
consumption, are significant improvements over previous
designs. These characteristics, plus the TCV
OS
of 0.3 μV/°C
maximum and the low V
OS
of 25 μV maximum, eliminates
the need for V
OS
adjustment 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.

Long-term input offset voltage stability refers to the averaged trend line of V
OS
vs. time over extended periods after the first 30 days of operation. Excluding the initial
hour of operation, changes in V
OS
during the first 30 operating days are typically 2.5 μV.
