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.
