Overview
The AD8601ARTZ-REEL, produced by Analog Devices Inc., is a single, rail-to-rail, input and output, single-supply operational amplifier. It is part of the AD8601, AD8602, and AD8604 family, which features very low offset voltage and wide signal bandwidth. This amplifier is designed using a new, patented trimming technique that achieves superior performance without the need for laser trimming. It is fully specified to operate on a single supply ranging from 2.7 V to 5.5 V, making it suitable for a variety of applications, including current sensing, barcode scanners, PA controls, and battery-powered instrumentation.
