GENERAL DESCRIPTION

This user guide describes the evaluation board for the AD5758,
a functional safety certified, single-channel, voltage and current
output, digital-to-analog converter (DAC) with on-chip dynamic
power control (DPC) that minimizes package power dissipation.
For full details on the AD5758, refer to the
Consult the data sheet when using the EVAL-AD5758SDZ. The
configuration of the various link options is explained in the
Evaluation Board Hardware section. The installation of the
companion software is discussed in the Software Quick Start
