–IN A 2 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. …
