Overview
The OP2177ARM-REEL, produced by Analog Devices Inc., is part of the OPx177 series, which represents the fourth generation of the industry-standard OP07 amplifier family. This high precision, low noise operational amplifier is renowned for its extremely low offset voltage and very low input bias currents. It is designed to offer superior performance over its predecessors, such as the OP07, OP77, and OP177, and is available in compact MSOP and SOIC packages.
