This document describes the features of the OPA177 precision bipolar op amp produced by Burr-Brown Corporation. The amplifier has low offset voltage and drift, high open-loop gain, low quiescent current, etc. It is suitable for precision instrumentation, data acquisition, test equipment, bridge amplifier, thermocouple amplifier, etc.
The document is a technical datasheet for the Burr-Brown OPA177 precision bipolar operational amplifier. It highlights key features such as low offset voltage (25uV max), low drift (0.3uV/°C), and high open-loop gain (130dB min). The device is designed to replace industry-standard op amps like the OP-07, OP-77, and OP-177, making it suitable for precision instrumentation, data acquisition, and test equipment applications. Packaging options include 8-pin plastic DIP and SO-8 surface-mount packages.
