The AD8554ARUZ is a zero-drift quad Operational Amplifier with rail-to-rail input/output. It is guaranteed to operate from 2.7 to 5V with a single supply. The AD8554 provide the benefits previously found only in expensive auto-zeroing or chopper-stabilized amplifiers. No external capacitors are required. With an offset voltage of only 1μV and drift of 0.005μV/°C, the AD8554 is perfectly suited for applications in which error sources cannot be tolerated. Temperature, position and pressure sensors and strain gage amplifier benefit greatly from nearly zero drift over their operating temperature range. The rail-to-rail input and output swings provided by the AD8554 make both high-side and low-side sensing easy.
