GENERAL DESCRIPTION  
TOP VIEW  
(Not to Scale)  
The AD8538/AD8539 are very high precision amplifiers featuring  
extremely low offset voltage, low input bias current, and low power  
consumption. The supply current is less than 215 μA maximum  
per amplifier at 5.0 V. Operation is fully specified from 2.7 V to  
5.0 V single supply ( 1.35 V to 2.5 V dual supply).

The AD8538/AD8539 are specified over the extended industrial  
temperature range (−40°C to +125°C). The AD8538 amplifier is  
available in 5-lead TSOT-23, and 8-lead, narrow body SOIC  
packages, and the AD8539 amplifier is available in 8-lead, narrow  
body SOIC and 8-lead MSOP. See the Ordering Guide for the  
automotive part.
