PRODUCT 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 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/µs and low input offset volt-
age 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 common-
mode 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 capaci-
tive loads, a small series resistor is needed to avoid excessive
peaking or overshoot.

Information furnished by Analog Devices is believed to be accurate and
reliable. However, no responsibility is assumed by Analog Devices for its
use, nor for any infringements of patents or other rights of third parties that
may result from its use. No license is granted by implication or otherwise
under any patent or patent rights of Analog Devices.
The AD8039 amplifier is the only dual low power, high speed
amplifier available in a tiny SOT23-8 package, and the single
AD8038 is available in both a SOIC-8 and a SC70-5 package.
These amps are rated to work over the industrial temperature
range of –40°C to +85°C.
