GENERAL DESCRIPTION 

This user guide details the operation of the evaluation boards 
for th

AD5676

/

AD5676R

 octal channel, voltage output digital-

to-analog converter (DAC). 
The

boards help users to quickly prototype new

circuits and reduce design time. The 

AD5676

/

AD5676R

 operate 

from a single 2.7 V to 5.5 V supply. Th

AD5676R

 has an internal 

2.5 V reference giving a maximum output voltage of 2.5 V or 5 V. 
The 

AD5676

 does not have an internal reference; therefore, an 

ADR431

 is provided on-board as a 2.5 V reference source. A 

different reference voltage can be applied via the EXT_REF SMB 
connector, if required.  
Full data on the 

AD5676

/

AD5676R

 are available in the respective 

product data sheets, available from Analog Devices, which should 
be consulted in conjunction with this user guide when using the 
evaluation boards. 
The evaluation boards interface to the USB port of a PC via the 
SDP board. The Analysis Control Evaluation (ACE) software is 
available for use with the evaluation board to allow the user to 
program the 

AD5676

AD5676R

 

The evaluation boards are compatible with th

EVAL-SDP-CB1Z
