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.
