GENERAL DESCRIPTION  
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.  
With an offset voltage of only 1 μV and drift of 0.005 μV/°C, 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 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.  
The AD857x family is specified for the extended industrial/  
automotive (−40°C to +125°C) 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 14-lead narrow SOIC  
and 14-lead TSSOP packages.
