Data Sheet
EVALUATION BOARD
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.
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.
