GENERAL DESCRIPTION
The ADA4870-KGDis a unity-gain stable, high speed current
feedbackamplifier capable of delivering 1 A of output current
and 2500 V/µs slew rate from a 40 V supply. Manufactured
using the Analog Devices, Inc., proprietary high voltage extra
fast complementary bipolar (XFCB)process, the innovative
architecture of the ADA4870-KGD enables high output power,
high speed signalprocessing solutions in applications that
require driving a low impedance load.
The ADA4870-KGDis available in a 26-pad bare die. The
ADA4870-KGD operatesoverthe industrial temperature range
(−40°C to +85°C).
Additional application and technical information can be found
in the ADA4870 data sheet.
Known Good Die (KGD): these die are fully guaranteed to data
sheet specifications.
The ADA4870-KGDis ideal for driving high voltage power
FETs, piezo transducers, PIN diodes, CCD panels, anda variety
of other demanding applications that requirehigh speed from
high supply voltage at high output current.
