The AD8551ARMZ is a zero-drift single Operational Amplifier with rail-to-rail input/output. It is guaranteed to operate from 2.7 to 5V with a single supply. The AD8551 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 AD8551 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 AD8551 make both high-side and low-side sensing easy.
