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/
μ
s 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.
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
