EVALUATION BOARD
GENERAL DESCRIPTION
The AD9709-EB is an evaluation board for the AD9709 8-bit
dual DAC. Careful attention to layout and circuit design,
combined with a prototyping area, allow the user to easily and
effectively evaluate the AD9709 in any application where high
resolution, high speed conversion is required.
This board allows the user flexibility to operate the AD9709 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
AD9709, best performance is obtained when running the digital
supply (DVDD1/DVDD2) at 3.3 V and the analog supply
(AVDD) at 5 V.
