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.
