Data Sheet Low Power, Precision, Auto-Zero Op Amps AD8538/AD8539 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 APPLICATIONS Mobile communications Portable instrumentation Battery-powered devices Sensor interfaces Temperature measurement Electronic scales 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). 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 (−40°C t.
