EVALUATION BOARD OVERVIEW

This user guide details the design and setup of the evaluation
board for the ADAU1962/ADAU1966. Because the
is a 12-channel device and the
device, the DAC 13 through DAC 16 outputs do not function
on the
ADAU1962
evaluation board. The evaluation board must
be connected to an external 12 V dc power supply and ground; the
board draws approximately 150 mA.

The board has an S/PDIF receiver with RCA and optical
connectors, as well as a discrete serial audio interface that is
available on the Analog Devices, Inc. system development
platform (SDP) interface. Analog outputs are accessible with two
D-sub, 25-pin connectors using the professional audio standard. A
single D-sub, 25-pin to XLR male cable is included with the board
for connecting individual DAC channels to an audio system.
