GENERAL DESCRIPTION
This new family of amplifiers has ultralow offset, drift and bias current. The AD8571, AD8572 and AD8574 are single, dual and quad amplifiers 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 the benefits previously found only in expensive autozeroing or chopper-stabilized amplifiers. Using Analog Devices’ new topology these new zero-drift amplifiers combine low cost with high accuracy. (No external capacitors are required.) In addition, using a patented spread-spectrum autozero technique, the AD857x family virtually eliminates the intermodulation effects from interaction of the chopping function with the signal frequency in ac applications.
