GENERAL DESCRIPTION

This family of amplifiers has ultralow offset, drift, and bias current. The AD8571/AD8572/AD85741are single, dual, and quad
amplifiers, respectively, featuring rail-to-rail input and output swings. All are guaranteed to operate from 2.7 V to 5 V single supply.

With an offset voltage of only 1 μV and drift of 0.005 μV/°C, the AD8571/AD8572/AD8574 are 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 their operating temperature range. Many more systems require the rail-to-rail input and
output swings provided by the AD8571/AD8572/AD8574.
