GENERAL DESCRIPTION

This user guide details the operation of the

EVAL-AD5696RSDZ

evaluation board for the

AD5696R

quad-channel, voltage output,

digital-to-analog converter (DAC).

The

EVAL-AD5696RSDZ

evaluation board is designed to help

users quickly prototype

AD5696R

circuits and reduce design

time. The

AD5696R

operates from a single 2.7 V to 5.5 V supply.

The

AD5696R

incorporates an internal 2.5 V reference to give

an output voltage of 2.5 V or 5 V. The

EVAL-AD5696RSDZ

evaluation board also incorporates additional voltage references.

The

EVAL-AD5696RSDZ

interfaces to the USB port of a PC via

a system demonstration platform (

SDP

) board. The analysis

control evaluation (

ACE

) software is available for download

from the

EVAL-AD5696RSDZ

product page to use with the

evaluation board to allow the user to program the

AD5696R

. A

PMOD connection is also available to allow the connection of
microcontrollers to the evaluation board without the

SDP

board. Note that when a microcontroller is used through the
PMOD connection, the

SDP

board must be disconnected, and

the user is unable to operate the

ACE

software.

The

EVAL-AD5696RSDZ

evaluation board is compatible with

any Analog Devices

SDP

board, which can be purchased separ-

ately. A typical connection between the

EVAL-AD5696RSDZ

and the

EVAL-SDP-CS1Z

board (

SDP-S

controller board) is

shown in Figure 1.

For full details, see the

AD5696R

data sheet, which must be

used in conjunction with this user guide when using the

EVAL-

AD5696RSDZ

evaluation board.
