Overview
The AD8554AR-REEL is a quad operational amplifier produced by Analog Devices Inc. It belongs to the AD8551/AD8552/AD8554 family of zero-drift amplifiers, known for their high accuracy and low cost. These amplifiers feature rail-to-rail input and output swings and are designed to operate from a single supply voltage ranging from 2.7 V to 5 V. The AD8554AR-REEL is particularly suited for applications requiring high precision and minimal error, thanks to its ultra-low offset voltage and drift.
