AD8551ARZ

The AD8551ARZ is a Zero Drift Single Rail-to-rail Input/Output Operational Amplifier guaranteed to operate from 2.7V to 5V with a single supply. This amplifier provides 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, medical equipment and strain gage amplifiers benefit greatly from nearly zero drift over its operating temperature range. The rail-to-rail input and output swings provided by the AD8551 make both high-side and low-side sensing easy.
