GENERAL DESCRIPTION

This user guide describes the evaluation board for the AD5064

quad 16-bit digital-to-analog convertor (DAC). The AD5064

operates from a single 4.5 V to 5.5 V supply. There is an external

reference, which is the REF195 on this evaluation board.

Complete specifications for the AD5064 are found in the data

sheet available from Analog Devices, Inc., and should be con-

sulted in conjunction with this user guide when using the

evaluation board.

The evaluation board interfaces to the USB port of an IBM®-

compatible PC. Software is available with the evaluation board

allowing the user to easily program the AD5064.

Evaluation Board User Guide UG-144 EVALUATION BOARD HARDWARE POWER SUPPLIES LINK OPTIONS To power the EVAL-AD5064EBZ, supply 5.5 V between the AVDD and AGND inputs for the analog supply of the AD5064. Alternatively, placing Link 6 in Position B powers the analog circuitry from the USB port (default setting). A number of link and switch options on the evaluation board should be set for the required operating setup before using the board.
