APPLICATIONS q PRECISION INSTRUMENTATION q DATA ACQUISITION q TEST EQUIPMENT q BRIDGE AMPLIFIER q THERMOCOUPLE AMPLIFIER 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 thermoV+ 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.
