GENERAL DESCRIPTION 

This user guide supports the EVAL-AD5761RSDZ evaluation 
board, Revision D. The 

UG-751

 user guide supports previous 

revisions of the evaluation board. 

The EVAL-AD5761RSDZ is a fully featured evaluation board that 
allows the user to easily evaluate all the features of the 

AD5761R

 

16-bit, voltage output digital-to-analog converter (DAC). The 

AD5761R

 pins are accessible at on-board connectors for external 

connection. The evaluation board can be controlled by two means: 
via the on-board peripheral module (PMOD) connector (J5), or 
via the system demonstration platform (SDP) connector (J1).  

The evaluation board also integrates a power solution utilizing 
the 

ADP5070

 switching regulator and linear regulators (

ADP7142

ADP7182

) to generate a bipolar supply of up to −13 V and +23.2 V  

from a single supply as low as +3 V. The 3 V input voltage is 
supplied with a linear power supply via the on-board connector 
(PVIN_3V–15V), through the USB port connector (USB_ 
POWER), or from the SDP-B controller board. The bipolar supply 
generated by the power solution allows the DAC to operate in any 
of the available eight different output ranges. Alternatively, the 
DAC can be supplied with a linear power supply via the on-board 
connector (J4). 

The 

EVAL-SDP-CB1Z

 SDP-B board allows the EVAL- 

AD5761RSDZ to be controlled through the USB port of a 
Windows® based PC featuring Windows XP or later, using the 

AD5761R

 evaluation software. 

The 

AD5761R

 is a single channel, 16-bit serial input, voltage output 

DAC. The device operates from single supply voltages from 
+4.75 V up to +30 V, or dual supply voltages from −16.5 V to 
0 V (V

SS

) and +4.75 V to +16.5 V (V

DD

). The nominal full-scale 

output range is software or hardware selectable. The integrated 
output amplifiers, reference buffers, and power-up/power-down 
control circuitry provide an easy to use, universal solution. 

Complete specifications for the 

AD5761R

 are available in the 

AD5761R

 data sheet, which should be consulted in conjunction 

with this user guide when using this evaluation board.
