... The supply current is less than 215 μA maximujm per amplifier at 5.0 V. Operation is fully specified from 2 5.0 V single supply (±1. ±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 (− ...
