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 to +125°C). The AD8538 amplifier is available in 5-lead TSOT-23, and 8-lead, narrow body SOIC packages, and the AD8539 amplifier is available in 8-lead, narrow body SOIC and 8-lead MSOP.
