The AD8038 (single) and AD8039 (dual) amplifiers are high speed (350 MHz) voltage feedback amplifiers with an exceptionally low quiescent current of 1.0 mA/amplifier typical (1.5 mA max). The AD8038 single amplifier in the SOIC-8 package has a disable feature. Despite being low power and low cost, the amplifier provides excellent overall performance. Additionally, it offers a high slew rate of 425 V/s and low input offset voltage of 3 mV max.

ADI's proprietary XFCB process allows low noise operation (8 nV/HZ and 600 fA/HZ) at extremely low quiescent currents. Given a wide supply voltage range (3 V to 12 V), wide bandwidth, and small packaging, the AD8038 and AD8039 amplifiers are designed to work in a variety of applications where power and space are at a premium.

The AD8038 and AD8039 amplifiers have a wide input commonmode range of 1 V from either rail and will swing within 1 V of each rail on the output. These amplifiers are optimized for driving capacitive loads up to 15 pF. If driving larger capacitive loads, a small series resistor is needed to avoid excessive peaking or overshoot.
