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,
piezoelectric 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 printed circuit board (PCB) and heat sink
enabling efficient heat transfer for improved reliability in
demanding environments. The ADA4870 operates over the
industrial temperature range of −40°C to +85°C.
The ADA4870ARR-EBZ evaluation board 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.
