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 dramatically reduce warm-up drift and errors due to thermo V+ 7 Trim 1 14kΩ Trim 8 electric effects in input interconnections. It provides an effective alternative to chopper-stabilized amplifiers. The low noise of the OPA177 maintains accuracy. OPA177 performance gradeouts are available. Packaging options include 8-pin plastic DIP and SO-8 surface-mount packages.
