GENERAL DESCRIPTION
The ADA4870 is a 40 V, unity-gain stable, high speed current
feedback amplifier capable of delivering 1 A of output current
from a 40 V supply. Manufactured using the Analog Devices,
Inc., proprietary high voltage XFCB process, the innovative
architecture of the ADA4870 enables high output power, high
speed signal processing solutions in a variety of demanding
applications.
The ADA4870 is ideal for driving high voltage power
FETs, piezo transducers, PIN diodes, and a variety of other
demanding applications that require high speed from high
supply voltage and high current output.
The ADA4870 is available in a power SOIC package (PSOP_3)
featuring an exposed thermal slug that provides high thermal
conductivity to the PCB and heat sink enabling efficient heat
transfer for improved reliability in demanding environments.
The ADA4870 operates over the industrial temperature range
(−40°C to +85°C).
The evaluation board, ADA4870ARR-EBZ, provides a platform
for quick and easy evaluation of the ADA4870. Figure 1 shows
the top side of the evaluation board. Figure 2 shows the bottom
side of the board with the large exposed copper area for
applying a heat sink as needed.
