GENERAL DESCRIPTION
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 operate at very low power making these
amplifiers ideal for battery-powered devices and portable
equipment.
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.
