This family of amplifiers has ultralow offset, drift, and bias current. The AD8571, AD8572, and AD8574 are 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.
The AD857x family provides benefits previously found only in expensive auto-zeroing or chopper-stabilized amplifiers. Using Analog Devices, Inc. topology, these zero-drift amplifiers combine low cost with high accuracy. (No external capacitors are required.) Using a patented spread-spectrum auto-zero technique, the AD857x family eliminates the intermodulation effects from interaction of the chopping function with the signal frequency in ac applications.
With an offset voltage of only 1 V and drift of 0.005 V/, the AD857x family 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 their operating temperature range. Many more systems require the rail-to-rail input and output swings provided by the AD857x family.
The AD857x family is specified for the extended industrial/ automotive (−40 to +125) temperature range. The AD8571 single amplifier is available in 8-lead MSOP and narrow 8-lead SOIC packages. The AD8572 dual amplifier is available in 8-lead narrow SOIC and 8-lead TSSOP surface mount packages. The AD8574 quad amplifier is available in narrow 14-lead SOIC and 14-lead TSSOP packages.
