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).

FEATURES
   Low offset voltage: 13 µV maximum
   Input offset drift: 0.03 µV/°C
   Single-supply operation: 2.7 V to 5.5 V
   High gain, CMRR, and PSRR
   Low input bias current: 25 pA
   Low supply current: 180 µA
   Qualified for automotive applications
