DESCRIPTION
The OPA177 precision bipolar op amp feature very
low offset voltage and drift. Laser-trimmed offset,
drift and input bias current virtually eliminate the need
for costly external trimming. The high performance
and low cost make them ideally suited to a wide range
of precision instrumentation.
The low quiescent current of the OPA177 dramati-
cally reduce warm-up drift and errors due to thermo-

electric effects in input interconnections. It provides
an effective alternative to chopper-stabilized amplifi-
ers. The low noise of the OPA177 maintains accuracy.
OPA177 performance gradeouts are available. Pack-
aging options include 8-pin plastic DIP
and SO-8 surface-mount packages.
