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/s 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 55C to +105C. noise operation (8 nV/Hz and 600 fA/Hz) at extremely low 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.
