GENERAL DESCRIPTION
The AD8027/AD8028
1
is a high speed amplifier with rail-to-
rail input and output that operates on low supply voltages and
is optimized for high performance and wide dynamic signal
range. The AD8027/AD8028 has low noise (4.3 nV/√Hz,
1.6 pA/√Hz) and low distortion (120 dBc @ 1 MHz). In appli-
cations that use a fraction of or the entire input dynamic range
and require low distortion, the AD8027/AD8028 is an ideal
choice.
Many rail-to-rail input amplifiers have an input stage that
switches from one differential pair to another as the input sig-
nal crosses a threshold voltage, which causes distortion. The
AD8027/AD8028 has a unique feature that allows the user to
select the input crossover threshold voltage through the
SELECT pin. This feature controls the voltage at which the
complementary transistor input pairs switch. The AD8027/
AD8028 also has intrinsically low crossover distortion.

With its wide supply voltage range (2.7 V to 12 V) and wide
bandwidth (190 MHz), the AD8027/AD8028 amplifier is
designed to work in a variety of applications where speed and
performance are needed on low supply voltages. The high per-
formance of the AD8027/AD8028 is achieved with a quiescent
current of only 6.5 mA/amplifier typical. The AD8027/AD8028
has a shut down mode that is controlled via the SELECT pin.
The AD8027/AD8028 is available in SOIC-8, MSOP-10, and
SOT-23-6 packages. They are rated to work over the industrial
temperature range of –40°C to +125°C.
