The AD8039-EP dual amplifier is a high speed (350 MHz) voltage The AD8039-EP amplifier has a wide input common-mode range feedback amplifier with an exceptionally low quiescent current of 1 V from either rail and swings to within 1 V of each rail on the of 1.0 mA per amplifier typical (1.5 mA maximum). Despite its output. This amplifier is optimized for driving capacitive loads up low power and low cost, the amplifier provides excellent overall to 20 pF. If driving larger capacitive loads, a small series resistor performance. Additionally, it offers a high slew rate of 425 V/μs is needed to avoid excessive peaking or overshoot. and a low input offset voltage of 3 mV maximum. The AD8039-EP amplifier is available in an 8-lead SOIC package The Analog Devices, Inc., proprietary XFCB process allows low and is rated to work over the extended temperature range of noise operation (8 nV/√Hz and 600 fA/√Hz) at extremely low −55°C to +105°C. quiescent currents. Given its wide supply voltage range (3 V to Additional application and technical information can be found in 12 V), wide bandwidth, and small packaging, the AD8039-EP the AD8038/AD8039 data sheet. amplifier is designed to work in a variety of applications where power and space are at a premium.
