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 

AD5678

 

operates from a single 2.7 V to 5.5 V supply.  

For full data, see the 

AD5678

 data sheet, which must be consulted 

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 

EVAL-
