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.  
14-Lead SOIC  
(R Suffix)  
14-Lead TSSOP  
(RU Suffix)  
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.

With an offset voltage of only 1 µV and drift of 0.005 µV/°C, the  
AD8571 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.  
8
The AD857x family is specified for the extended industrial/automotive  
(–40°C to +125°C) temperature range. The AD8571 single is  
available in 8-lead MSOP and narrow 8-lead SOIC packages. The  
AD8572 dual amplifier is available in 8-lead narrow SO and 8-lead  
TSSOP surface mount packages. The AD8574 quad is available in  
narrow 14-lead SOIC and 14-lead TSSOP packages.
