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.

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.

The low quiescent current of the OPA177 dramati-

cally reduce warm-up drift and errors due to thermo-
