–IN B
+IN B
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 maximujm
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.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
