AD9744
EVALUATION BOARD
GENERAL DESCRIPTION
The TxDAC family evaluation boards allow for easy setup and
testing of any TxDAC product in the SOIC and LFCSP pack-
ages. Careful attention to layout and circuit design, combined
with a prototyping area, allows the user to evaluate the AD9744
easily and effectively in any application where high resolution,
high speed conversion is required.

This board allows the user the flexibility to operate the AD9744
in various configurations. Possible output configurations in-
clude transformer coupled, resistor terminated, and single and
differential outputs. The digital inputs are designed to be driven
from various word generators, with the on-board option to add
a resistor network for proper load termination. Provisions are
also made to operate the AD9744 with either the internal or
external reference or to exercise the power-down feature.
