Evaluation Board User Guide

GENERAL DESCRIPTION

This user guide describes the EVAL-AD5423SDZ evaluation
board for the
AD5423
single-channel, 16-bit voltage, 16-bit
current output digital-to-analog converter (DAC).
The EVAL-AD5423SDZ (see Figure 1) requires the
CS1Z
system demonstration platform (SDP-S) board. The
EVAL-AD5423SDZ interfaces to the USB port of the PC via the
SDP-S
board. The Analysis, Control, Evaluation (ACE) software
allows simplified programming of the AD5423, and is available
to use with the EVAL-AD5423SDZ.
For full details on the AD5423, see the
Consult the data sheet in conjunction with this user guide when
using the EVAL-AD5423SDZ.
