GENERAL DESCRIPTION
(Continued from Page 1)
PSRR and CMRR exceed 120 dB. These characteristics, coupled
with long-term drift of 0.2 µV/month, allow the circuit designer
to achieve performance levels previously attained only by discrete
designs.
Low cost, high volume production of
OP27
is achieved by
using an on-chip Zener zap-trimming network. This reliable
and stable offset trimming scheme has proven its effectiveness
over many years of production history.
OP27
The
OP27
provides excellent performance in low noise,
high accuracy amplification of low level signals. Applications
include stable integrators, precision summing amplifiers,
precision voltage threshold detectors, comparators, and
professional audio circuits such as tape heads and microphone
preamplifiers.

Input offset voltage measurements are performed approximately 0.5 seconds after application of power. A/E grades guaranteed fully warmed up.
Long-term input offset voltage stability refers to the average 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 days are typically 2.5 µV. Refer to the Typical Performance Characteristics section.
