GENERAL DESCRIPTION
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 maximum).
The AD8038 single amplifier in the 8-lead SOIC 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/μs and a low input offset voltage of 3 mV
maximum.
The Analog Devices, Inc., 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 common-
mode range of 1 V from either rail and swing to 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.

The AD8039 amplifier is available in a 8-lead SOT-23 package,
and the single AD8038 is available in both an 8-lead SOIC and a
5-lead SC70 package. These amplifiers are rated to work over
the industrial temperature range of −40°C to +85°C.
