EVALUATION BOARD
GENERAL DESCRIPTION
The TxDAC family evaluation boards allow for easy setup and
testing of any TxDAC product in the SOIC and LFCSP packages.
Careful attention to layout and circuit design, combined with a
prototyping area, allows the user to evaluate the AD9740 easily
and effectively in any application where high resolution, high
speed conversion is required.

This board allows the user the flexibility to operate the AD9740
in various configurations. Possible output configurations
include 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 AD9740 with either the internal or
external reference or to exercise the power-down feature.
