EVALUATION BOARD

GENERAL DESCRIPTION

The AD9763/AD9765/AD9767-EBZ is an evaluation board

for the AD9763/AD9765/AD9767 10-/12-/14-bit dual DAC.

Careful attention to layout and circuit design, combined with a

prototyping area, allow the user to easily and effectively evaluate

the AD9763/AD9765/AD9767 in any application where a high

resolution, high speed conversion is required.

This board allows the user the flexibility to operate the AD9763/

AD9765/AD9767 in various configurations. Possible output

configurations include transformer coupled, resistor terminated,

and single-ended and differential outputs. The digital inputs can be

used in dual-port or interleaved mode and are designed to be

driven from various word generators, with the on-board option

to add a resistor network for proper load termination. When

operating the AD9763/AD9765/AD9767, best performance is

obtained by running the digital supply (DVDD1/DVDD2) at

3.3 V and the analog supply (AVDD) at 5 V.
