GENERAL DESCRIPTION
This user guide details the operation of the evaluation board for
the AD5338R dual-channel, voltage output, digital-to-analog
converter (DAC).
The evaluation board is designed to help users quickly prototype
new AD5338R circuits and reduce design time. The AD5338R
operates from a single 2.7 V to 5.5 V supply.
Full details can be found in the AD5338R 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-
AD5338RDBZ evaluation board page to allow the user to
program the AD5338R.

EVALUATION BOARD HARDWARE
MOTHERBOARD POWER SUPPLIES
The E VA L-MBnanoDAC-SDZ motherboard supports single and
dual power supplies.
The E VA L-AD5338RDBZ evaluation board can be powered either
from the SDP-B port or externally by the J5 and J6 connectors,
as described in Table 1.
Both AGND and DGND inputs are provided on the board. The
AGND and DGND planes are connected at one location on the
E VA L-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.
Table 1. Power Supply Connectors
Connector No. Label Voltage
J5, Pin 1 (J5-1) VDD Analog positive power supply, VDD.
Single and dual supply 5.5 V.
J5, Pin 2 (J5-2) AGND Analog ground.
J5, Pin 3 (J5-3) VSS Analog negative power supply, VSS.
Dual supply −5.5 V.
J6, Pin 1 (J6-1) VLOGIC Digital supply from 1.8 V to VDD.
J6, Pin 2 (J6-2)
DGND
Digital ground.
MOTHERBOARD 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 4. The positions listed
in Table 2 and Table 4 match the evaluation board imprints (see
Figure 12).

EVALUATION BOARD SOFTWARE QUICK START PROCEDURES
INSTALLING THE SOFTWARE
The EVAL-AD5338RDBZ 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 when it connects to the PC.
To install the software, take the following steps:
1. Start the Windows operating system. Download the
installation software from the EVAL-AD5338RDBZ
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, do the following:
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,
AD5338R 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
AD5338R evaluation software then opens, as shown in Figure 4.

SOFTWARE OPERATION
The software for the AD5338R allows the user to program
values to the input and DAC registers of each DAC individually
or collectively.
Write to Input Register
Click Write to Input Register to load the code of the input data
control to the input register of 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. The LDAC mask register setting is ignored.
Write to Input and DAC Register
Click Write to Input and DAC Register 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. The LDAC mask is ignored.
LDAC Control
Click Pulse LDAC to bring the LDAC pin low and then back
high. This action copies the data from the input registers to the
DAC registers, and the outputs update accordingly. Any DAC
updates disabled by the LDAC mask settings are ignored.
Alternatively, the LDAC pin can also be set high or low by
clicking LDAC HIGH or LDAC LOW, respectively.
Power-Down Control
Each DAC can be powered down individually, and has an
associated selection box allowing the selected DAC to operate in
normal mode or power-down mode. Click the blue progressive
disclosure option on the POWER-DOWN LOGIC block to access
the Powerdown Configuration window, as shown in Figure 5.
When the power-down setting for the DAC is selected, click OK
to write the appropriate values to the AD5338R. The POWER
DOWN indicator LED lights up accordingly when a DAC is
powered down.

GAIN Control
To set the GAIN pin high or low, click the blue progressive
disclosure option on the GAIN SELECT block to access the
Gain Control window, as shown in Figure 6. In the GAIN
selection box, select X1 for a full-scale output of 2.5 V or select
X2 for a full-scale output of 5 V.
14514-106
Figure 6. Gain Control Window
LDAC Mask Register
Each DAC can be configured to respond to or ignore the LDAC
pin settings in the LDAC Configuration dropdown menu. Click
the blue progressive disclosure option on the LOGIC INTERFACE
block to access the LDAC Configuration window, as shown in
Figure 7. When the LDAC selections are completed, click OK to
write the appropriate values to the AD5338R. The LDAC MASK
indicator LED lights up accordingly when the LDAC mask of
the DAC is enabled.
