GENERAL DESCRIPTION  
The AD8538 is a very high precision amplifier featuring  
extremely low offset voltage, low input bias current, and low  
power consumption. The supply current is less than 180 μA 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 operates using very low power making this  
amplifier ideal for battery-powered devices and portable  
equipment.  
The AD8538 is 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.
