GENERAL DESCRIPTION
This user guide describes the EVAL-ADHV4702-1CPZ evalua-
tion board, which helps users evaluate the
a 7 mm × 7 mm, 12-lead lead frame chip scale package (LFCSP)
with an exposed pad at the bottom. The evaluation board provides
a platform for quick and easy evaluation of the ADHV4702-1.
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 attaching a heat sink to provide additional
thermal management.
The evaluation board is a 6-layer board designed to minimize
leakage currents with its guard ring feature. It accepts Subminia-
ture Version A (SMA) and Subminiature Version B (SMB) edge
mounted connectors on the inputs for easy connection to test
equipment or other circuitry.
The
ADHV4702-1
data sheet covers the specifications and details
of the device operation and application circuit configurations
and guidance. Full specifications of the
found in the
ADHV4702-1
data sheet, available from Analog
Devices, Inc., and must be consulted in conjunction with this
user guide, especially when powering up the evaluation board
for the first time.
For safety, the EVAL-ADHV4702-1CPZ evaluation board is
covered top and bottom with acrylic plastic guards to reduce
the risk of inadvertent contact with high voltage. Do not operate
the board without these guards in place. If the guards must be
removed to adjust jumpers or change component values, discon-
nect the board from the power supply before removing guards,
and replace the guards before powering up again. For full
precautions when using this high voltage evaluation board, see
the High Voltage Evaluation Board section.
