The AD8551ARZ-REEL is a single precision rail-rail chopper opamp made by Analog Devices. It is designed to provide high accuracy and low noise performance for precision signal conditioning, signal acquisition, and low level data acquisition applications. It features a low offset voltage, high open-loop gain, and rail-to-rail input/output capabilities. Its small footprint allows it to fit in a compact form factor, making it suitable for integration in small, portable electronics. With an input common-mode range extending beyond the supplies, the op-amp can be used for low level signal amplification, while its rail-to-rail output swing drives small loads with high accuracy.
