Evaluation Board for AD5686R/AD5686/AD5684R/AD5684
16-/12-Bit, Quad Channel Voltage Output DAC
The AD568x(R) is used in this user guide to refer to the AD5686R,
AD5686, AD5684R, and AD5684.
FEATURES
Full-featured evaluation board for the AD5686R, AD5686,
AD5684R, and AD5684
On-board references
Various link options
PC control in conjunction with Analog Devices, Inc., System
Demonstration Platform (SDP)
The evaluation board is designed to help customers quickly
prototype new AD568x(R) circuits and reduce design time.
The AD568x(R) operates from a single 2.7 V to 5.5 V supply.
The AD5686R and AD5684R incorporate an internal 2.5 V
reference to give an output voltage span of 2.5 V or 5 V. The
AD5686 and AD5684 require an external reference.
PACKAGE CONTENTS
Full data on the AD568x(R) can be found in the appropriate data
sheet available from Analog Devices and should be consulted in
conjunction with this user guide when using the evaluation board.
AD5686/AD5686R or AD5684/AD5684R evaluation board
CD includes
Self-installing software that allows users to control the
board and exercise all functions of the device
Electronic version of the AD5686R, AD5686, AD5684R, and
AD5684 data sheets
The evaluation board interfaces to the USB port of a PC via the
SDP board. Software is supplied with the evaluation board to
allow the user to program the AD568x(R).
Electronic version of UG-459
This evaluation board requires the EVAL-SDP-CB1Z board
(SDP-B controller board), which is available for order on the
Analog Devices website at www.analog.com.
GENERAL DESCRIPTION
This user guide details the operation of the evaluation board for
the AD5686R, AD5686, AD5684R, and AD5684 quad channel,
voltage output digital-to-analog converters (DACs).
The EVAL-AD5686RSDZ supports both the AD5686R and
AD5686, and the EVAL-AD5684RSDZ supports both the
AD5684R and AD5684.
