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