AD8572ARZ (ANALOG DEVICES)

The AD8572ARZ is a Zero-drift Single-supply Rail-to-rail Input/Output Dual Operational Amplifier guaranteed to operate from 2.7 to 5V single supply. It provides benefits previously found only in expensive auto-zeroing or chopper-stabilized amplifiers. Using a spread-spectrum and auto-zero technique, the AD8572 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 op amp is perfectly suited for applications where error sources cannot be tolerated. Position and pressure sensors, medical equipment and strain gage amplifiers benefit greatly from nearly zero drift over its operating temperature range. Many more systems require the rail-to-rail input and output swings provided by AD8572.
