3 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. High performance and low cost make these devices an excellent choice for a wide range of precision instrumentation.

The low quiescent current of the OPA177 dramatically reduces warm-up drift and errors due to thermoelectric effects in input interconnections. The OPA177 provides an effective alternative to chopper-stabilized amplifiers. The low noise of the OPA177 helps maintain maximum signal integrity.

OPA177 performance grade-outs are available. Packaging options include 8-pin plastic DIP and SO-8 surface-mount packages.
