GENERAL DESCRIPTION
This user guide details the operation of the evaluation board for
the
AD5678
octal channel, voltage output, digital-to-analog
converter (DAC).
The evaluation board is designed to help users quickly prototype
new
AD5678
circuits and reduce design time. The
operates from a single 2.7 V to 5.5 V supply.
For full data, see the
in conjunction with this user guide when using the evaluation
board.
The evaluation board interfaces to the USB port of a PC via the
SDP-B
board. Software is available for download from the
