AD8538/AD8539 Auto-Zero Op Amps

Analog Devices AD8538/AD8539 Auto-Zero Op Amps feature low offset voltage, low input bias current, and low power consumption. The amplifiers' supply current is less than 215µA maximum per amplifier at 5.0V. They operate fully specified from 2.7V to 5.0V single supply (±1.35V to ±2.5V dual supply). Their low power makes them ideal for battery-powered devices and portable equipment.
