GENERAL DESCRIPTION
This user guide details the operation of the evaluation board for
the AD5678 octal channel, voltage output, digital-to-analog
converter (DAC).
The evaluation board is designed to help users quickly prototype
new AD5678 circuits and reduce design time. The AD5678
operates from a single 2.7 V to 5.5 V supply.
For full data, see the AD5678 data sheet, which must 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-B board. Software is available for download from the EVAL-
AD5678DBZ evaluation board page to allow the user to program
the AD5678.

EVALUATION BOARD HARDWARE
MOTHERBOARD POWER SUPPLIES
The EVAL-MBnanoDAC-SDZ motherboard supports single
and dual power supplies.
The EVAL-AD5678DBZ evaluation board can be powered either
from the SDP port or externally by the J5 and J6 connectors, as
described in Table 1.
Both the AGND and DGND inputs are provided on the board.
The AGND and DGND planes are connected at one location on
the EVAL-MBnanoDAC-SDZ. It is recommended that AGND
and DGND not be connected elsewhere in the system to avoid
ground loop problems.
All supplies are decoupled to ground with 10 µF tantalum and
0.1 µF ceramic capacitors.

LINK OPTIONS
A number of link options are incorporated in the E VA L -
MBnanoDAC-SDZ and must be set for the required operating
conditions before using the board. Table 2 describes the positions of
the links to control the evaluation board via the SDP-B board
using a PC and external power supplies. The functions of these
link options are described in detail in Table 3. The positions listed
in Table 2 and Table 3 match the evaluation board imprints (see
Figure 12).

EVALUATION BOARD SOFTWARE QUICK START PROCEDURES
INSTALLING THE SOFTWARE
The EVAL-AD5678DBZ evaluation software is compatible with
Windows® Vista (64-bit/32-bit), and Windows 7 (64-bit/32-bit).
The software must be installed before connecting the SDP-B board
to the USB port of the PC to ensure that the SDP-B board is
recognized by the PC.
To install the software, take the following steps:
1. Start the Windows operating system. Download the
installation software from the EVAL-AD5678DBZ
evaluation board page.
2. Run the setup.exe file from the installer folder if it does not
open automatically.
3. After installation is completed, power up the evaluation
board as described in the Motherboard Power Supplies
section.
4. Connect the evaluation board to the SDP-B board and the
SDP-B board into the PC using the USB cable included in
the evaluation kit.
5. When the software detects the evaluation board, click
through any dialog boxes that appear to finalize the
installation.
RUNNING THE SOFTWARE
To run the program, take the following steps:
1. Connect the evaluation board to the SDP-B board and
connect the USB cable between the SDP-B board and the PC.
2. Power up the evaluation board as described in the
Motherboard Power Supplies section.
3. From the Start menu, click All Programs, Analog Devices,
AD5678 Evaluation Software.
4. If the SDP-B board is not connected to the USB port when
the software is launched, a connectivity error displays (see
Figure 2). Connect the evaluation board to the USB port of
the PC and wait a few seconds. When the SDP-B board is
detected, the display is updated (see Figure 3).
Alternatively, the software can be used without an evaluation
board. The software runs in simulation mode displaying expected
outputs based on the input data. The main window of the AD5678
evaluation software then opens, as shown in Figure 4.

SOFTWARE OPERATION
The software for the AD5678 allows the user to program values
to the DAC REGISTER of the DAC.
Write to Input Register
Click Write to Input Register to load the code of the input data
control to the input register of the selected DAC in the DAC
selection box.
Update DAC Register from Input Register
Click Update DAC Register from Input Register to copy the
value in the input register to the corresponding DAC register.
The DAC outputs are automatically updated with the appropriate
voltage.
Write to Input and DAC Registers
Click Write to Input and DAC Registers to load the code of the
input data control to the input register and DAC register of the
selected DAC. The DAC outputs are automatically updated with
the appropriate voltage.
LDAC Control
Click Pulse LDAC to bring the LDAC pin low and then back
high. This action copies the data from the input register to the
DAC register, and the output updates accordingly.
Alternatively, the LDAC pin can be set to logic high or logic low
by selecting the corresponding LDAC HIGH or LDAC LOW
option.
Power-Down Control
Each DAC can be powered down individually. Click the POWER-
DOWN LOGIC blue progressive disclosure option to access the
Powerdown Configuration window, as shown in Figure 5. The
selected DAC can operate in normal operation or one of the three
different power-down, pull-down termination options. When the
power-down setting for each DAC is selected, click OK to write
the appropriate values to the AD5678.
14523-005
Figure 5. Powerdown Configuration Window

UG-987 EVAL-AD5678DBZ User Guide
Rev. A | Page 6 of 13
Reference Control
The DAC has an on-chip reference with an internal gain of 2.
Click the blue progressive option on the REFERENCE INPUT
block to access the Reference Input window, as shown in Figure 6,
which allows the user to select between the on-chip reference or
external reference voltage.
14523-006
Figure 6. Reference Input Window
When using an external reference, write the actual value of the
reference voltage in the External Reference (V) input box to make
sure that the software reflects the voltage output correctly.
LDAC Mask Register
Each DAC can be configured to respond to or override the LDAC
pin settings in the LDAC control. Click the blue progressive
disclosure option on the INTERFACE LOGIC block to access
the LDAC Register window, as shown in Figure 7. When the
LDAC selections are completed, click OK to write the appropriate
values to the AD5678. The LDAC REGISTER indicator lights
up accordingly when an LDAC mask of a DAC is enabled.
