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.
