The AD8574-EP provides benefits previously found only in  
expensive auto-zeroing or chopper-stabilized amplifiers. Using  
a patented spread-spectrum, auto-zero technique, the AD8574  
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  
AD8574-EP is perfectly suited for applications where error  
sources must be minimized.  
The AD8574-EP is specified for the military temperature range  
(−55°C to +125°C). The AD8574-EP quad amplifier is available in  
a 14-lead TSSOP package.  
APPLICATIONS  
Additional applications and technical information is available in  
the AD8571/AD8572/AD8574 data sheets.

Precision current sensing

GENERAL DESCRIPTION  
This amplifier has ultralow offset, drift, and bias current. The  
AD8574-EP is a quad amplifier, featuring rail-to-rail input and  
output swings. It is guaranteed to operate from 2.7 V to 5 V  
single supply.
