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 AD568x(R) is used in this user guide to refer to the AD5686R,
AD5686, AD5684R, and AD5684.
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.
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.
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).
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.
The EVAL-AD5686RSDZ supports both the AD5686R and
AD5686, and the EVAL-AD5684RSDZ supports both the
AD5684R and AD5684.
