The AD8571ARZ is a zero-drift single Operational Amplifier with rail-to-rail input/output swings. The AD8571 provide benefits previously found only in expensive auto-zeroing or chopper-stabilized amplifiers. Using a spread-spectrum, auto-zero technique, the AD8571 eliminate the intermodulation effects from interaction of the chopping function with the signal frequency in AC applications. With an offset voltage of only 1μV and drift of 0.005μV/°C, the AD8571 is perfectly suited for applications where error sources cannot be tolerated. Position and pressure sensors and strain gage amplifiers benefit greatly from nearly zero drift over their operating temperature range.
