The document describes the features and characteristics of OPA177 precision bipolar operational amplifier produced by Burr-Brown Corporation. This product has low offset voltage, low drift, high open-loop gain, and low quiescent current, making it suitable for precision instrumentation, data acquisition, test equipment, bridge amplifier, and thermocouple amplifier applications.
The OPA177 is a precision bipolar operational amplifier featuring very low offset voltage and drift, making it suitable for precision instrumentation, data acquisition, and test equipment. It serves as an effective alternative to chopper-stabilized amplifiers and replaces industry-standard op amps such as the OP-07, OP-77, and AD707.
The document details electrical specifications including input offset voltage, bias current, noise, open-loop gain, and frequency response. It also includes absolute maximum ratings, package ordering information for 8-pin Plastic DIP and SO-8 surface-mount packages, and typical performance curves illustrating characteristics like total harmonic distortion, warm-up offset drift, and output swing.
