AD8475 EVALUATION BOARD
An evaluation board for the AD8475 is available to facilitate
standalone testing of the AD8475 performance and functionality
for customer evaluation and system design. The board provides
the user flexibility to configure the AD8475 in the desired gain
(0.4 or 0.8) and to install the suitable input and load impedances.
The AD8475-EVALZ board is designed so that a user can easily
evaluate system performance when the AD8475 is mated with
any Analog Devices, Inc., SAR ADC. The board can be installed
with SMB connectors that mate directly to the Pulsar® Analog-
to-Digital Converter Evaluation Kit.
See the AD8475 product page for more information on the
AD8475-EVALZ.
