GENERAL DESCRIPTION

This user guide details the operation of the E VA L -AD5313RDBZ

evaluation board for the AD5313R dual-channel, voltage output

DAC. The AD5313R operates from a single 2.7 V to 5.5 V supply.

The E VA L -AD5313RDBZ is designed to quickly prototype

AD5313R circuits and reduce design time. The evaluation board

interfaces with the USB port of a PC via the SDP-B controller

board. Software can be downloaded via the EVA L-AD5313RDBZ

product page that allows users to program the AD5313R.

This evaluation board requires the SDP-B controller board,

which is available for order on the Analog Devices, Inc.,

website.

Full data on the AD5313R can be found in the AD5313R data

sheet available from Analog Devices and should be consulted in

conjunction with this user guide when using the evaluation board.

EVALUATION BOARD HARDWARE

POWER SUPPLIES

The nanoDAC® E VA L-MBnanoDAC-SDZ motherboard

supports single and dual power supplies.

The E VA L -AD5313RDBZ 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 E VA L -

AD5313RDBZ evaluation board. The AGND and DGND planes

connect at one location on the E VA L -MBnanoDAC-SDZ. It is

recommended that AGND and DGND do not connect

elsewhere in the system to avoid ground loop problems.

All supplies are decoupled to ground with a 10 µF tantalum

capacitor and 0.1 µF ceramic capacitor.

LINK OPTIONS

A number of link options are incorporated in the EVA L -

MBnanoDAC-SDZ and must be set for the required operating

conditions before using the EVA L-AD5313RDBZ. Table 2

describes the positions of the links to control the evaluation

board via the SDP-B controller 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 SOFTWARE

INSTALLING THE EVAL-AD5313RDBZ EVALUATION

SOFTWARE

The E VA L -AD5313RDBZ evaluation software is compatible with

Windows® Vista (64-bit/32-bit), and Windows 7 (64-bit/32-bit).

Install the software before connecting the SDP-B controller

board to the USB port of the PC to ensure that the SDP-B

controller board is recognized when it connects to the PC.

To install the EVA L-AD5313RDBZ evaluation software, take

the following steps:

1. Start the Windows operating system.

2. Download the installation software from the E VA L-

AD5313RDBZ evaluation board page.

3. Run the setup.exe file from the installer folder if it does not

open automatically.

4. After the installation is complete, power up the evaluation

board as described in the Power Supplies section.

5. Connect the E VA L-AD5313RDBZ to the SDP-B controller

board and the SDP-B controller board to the PC using the

USB cable included in the evaluation kit.

6. When the software detects the E VA L-AD5313RDBZ,

proceed through any dialog boxes that appear to finalize

the installation.

RUNNING THE SOFTWARE

To run the E VA L -AD5313RDBZ evaluation software, proceed

with the following steps:

1. Connect the EVA L -AD5313RDBZ to the SDP-B controller

board and connect the USB cable between the board and

the PC.

2. Power up the E VA L -AD5313RDBZ as described in the

Power Supplies section.

3. Click Start > All Programs > Analog Devices > AD5313R

Evaluation Software to locate the evaluation board.

If the SDP-B controller board is not connected to the USB port

when the software launches, a connectivity error displays (see

Figure 2).

Connect the SDP-B controller board to the USB port of the PC

and wait a few seconds. When the SDP-B controller board and

the E VA L -AD5313RDBZ daughter board are detected, the

display updates (see Figure 3).

Figure 4. AD5313R Evaluation Software Main Window

Alternatively, the E VA L -AD5313RDBZ evaluation software can

be used without an evaluation board. The EVA L-AD5313RDBZ

evaluation software runs in simulation mode displaying

expected outputs based on the input data. The main window of

the E VA L-AD5313RDBZ evaluation software then opens, as

shown in Figure 4.

SOFTWARE OPERATION

The E VA L -AD5313RDBZ evaluation software allows the user to

program values to the input and DAC registers of each DAC

individually or collectively.

Write to Input Register

Click the Write to Input Register button to load the code of the

input data control to the input register of the selected DAC

(DAC A, DAC B, or All DACs).

Update DAC Register from Input Register

Click the Update DAC Register from Input Register button to

copy the value in the input register to the corresponding DAC

appropriated voltage. Ignore the LDAC MASK indicator LED.

Write to Input and DAC Registers

Click the Write to Input and DAC Registersbutton to load the

code of the input data control to the input register and DAC

updated with the appropriated voltage. Ignore the LDAC MASK

indicator LED.

LDAC Control

Select the Pulse LDAC button to bring the LDAC pin low and

then back to high, copying the data from the input registers to

the DAC registers, and the outputs update accordingly. Ignore

any DAC updates disabled by the LDAC mask settings.

The LDAC pin can also be set high or low by clicking LDAC

HIGH or LDAC LOW, respectively.

LDAC Mask Register

Each DAC can be configured to respond or ignore the LDAC

pin settings in the LDAC Control. Click the blue progressive

disclosure option on the LOGIC INTERFACE block to access

the LDAC Configuration window, as shown in Figure 5.

When the LDAC selections are completed, click OK to write the

appropriate values to the AD5313R. The LDAC MASK indicator

LED lights up accordingly when a DAC LDAC mask is enabled.

Rev. A | Page 6 of 13

Power-Down Control

DAC A and DAC B in the AD5313R can be powered down

individually. Each of the DACs has a selection box allowing the

selected DAC to operate in normal mode or power-down mode.

Click on the blue progressive disclosure button on the POWER-

DOWN LOGIC block to access the Powerdown Configuration

window, shown in Figure 6. When the power-down setting for

the DAC is selected, click OK to write the appropriate values to

the AD5313R. The POWER DOWN indicator LED lights up

accordingly when a DAC powers down.

Figure 6. Powerdown Configuration Window

GAIN Control

Set the GAIN pin high or low by clicking the blue progressive

disclosure button on the GAIN SELECT block to access the Gain

Control window, shown in Figure 7. Select GAIN X1 to give a full-

scale output of 2.5 V or select GAIN X2 to give a full-scale output

of 5 V.
