Overview
The OP777AR-REEL, produced by Analog Devices Inc., is a precision single-supply operational amplifier known for its micropower operation and rail-to-rail output. This amplifier is part of the OP777, OP727, and OP747 family, which includes single, dual, and quad configurations. The OP777AR-REEL is designed to offer high performance in low-power applications, making it suitable for both line-powered and portable instrumentation. It features improved performance over industry-standard amplifiers like the OP07, with the added benefit of true single-supply operation and smaller package options.
