GENERAL DESCRIPTION
The AD5443, AD5446,and AD5453 are CMOS 12-bit, 14-bit,
and 14-bit, respectively, current output, digital-to-analog
converters (DACs). The AD5443 operates from a 3 V to 5.5 V
power supply, while the AD5446 and AD5453 operate from a
single 2.5 V to 5.5 V power supply. These devices are well suited
for portable battery-powered and applications such as waveform
generation and analog processing.
Because of the CMOS submicron manufacturing process, these
parts offer excellent 4-quadrant multiplication characteristics of
10 MHz for the AD5443 and up to 12 MHz for the AD5446 and
AD5453 DACs.
These DACs use a double-buffered, 3-wire serial interface that
is compatible with SPI, QSPI™, MICROWIRE™, and most DSP
interface standards. On power-up, the internal shift register and
latches are filled with 0s, and the DAC output is at zero scale. In
addition for the AD5443 and AD5446, a serial data out pin
(SDO) allows for daisy chaining when multiple packages are
used. Data readback allows the user to read the contents of the
DAC register via the SDO pin.
PLEASE SEE THE LAST PAGE FOR AN IMPORTANT
WARNING AND LEGAL TERMS AND CONDITIONS.
Rev. B | Page 1 of 12
The applied external reference input voltage (VREF) determines
the full-scale output current. An integrated feedback resistor
(RFB) provides temperature tracking and full-scale voltage output
when combined with an external current-to-voltage precision
amplifier.
The AD5443 and AD5446 are available in small 10-lead MSOP
packages, while the AD5453 is available in small 8-lead TSOT,
MSOP packages, also comes in 8-lead LFCSP.
The EV-AD5443/46/53SDZ board is used in conjunction with
the EVAL-SDP-CB1Z system demonstration platform (SDP)
board available from Analog Devices, Inc., which is purchased
separately from the evaluation board. The USB-to-SPI
communication to the DAC is completed using this Blackfin®based demonstration board.

EVALUATION BOARD SOFTWARE
Figure 2. Device Manager Showing the SDP Board Connected
INSTALLING THE SOFTWARE
RUNNING THE SOFTWARE
The EV-AD5443/46/53SDZ evaluation kit includes the software
and drivers on CD. To install the software, follow these steps:
To run the evaluation board program, do the following:
2.
3.
4.
5.
Install the software before connecting the SDP board to
the USB port of the PC.
Start the Windows® operating system and insert the
EV-AD5443/46/53SDZ evaluation kit CD.
Download the EV-AD5443/46/53SDZ LabVIEW™ software.
The correct driver, SDPDriversNET, for the SDP board
should download automatically after LabVIEW is
downloaded, supporting both 32-bit and 64-bit systems.
However, if the drivers do not download automatically, the
driver executable file can also be found in the Program
Files/Analog Devices folder. Follow the on-screen prompts
to install it.
After installation of the software and drivers is complete,
plug the EV-AD5443/46/53SDZ into the SDP board and the
SDP board into the PC using the USB cable included in the
box.
When the software detects the evaluation board, proceed
through any dialog boxes that appear to finalize the
installation (Found New Hardware Wizard/Install the
Software Automatically and so on).

Rev. B | Page 3 of 12
Click Start/All Programs/Analog Devices/
EV-AD5443/46/53SDZ.
If the SDP board is not connected to the USB port when
the software is launched, a connectivity error displays (see
Figure 3). Simply connect the evaluation board to the USB
port of the PC, wait a few seconds, click Rescan, and follow
the instructions.

Once the software is launched, the main window pops up
(see Figure 4).

EXAMPLE 1
Select the AD5453 part from the main window. Check the
Clock Data To Shift Register on Rising Edge box, and click the
OK button. The AD5453 Evaluation Software Window should
appear. The LED indicator with the Rising Edge Active label
should be lit indicating the actual functionality mode (see
Figure 5).
Enter Data 0x2000 (half scale) in the Input Data control and
click the Write to DAC button. Data is clocked on the rising
edge instead of the falling edge (by default). There is no loss of
data; therefore, the output shows the expected −5 V value. The
only change is the way the data is clocked.
VOUT = −VREF ×
D

EXAMPLE 2
Select the AD5446 part from the main window and click the
OK button. The AD5446 Evaluation Software Window should
appear. Enter Data 0x3FFF (full scale) in the Input Data control
and click the Write to DAC button. The output shows −10 V, and
because this write was the first action on the DAC after powering
up, the data on the SDO pin is not taken into account because
the data is not given any information.
VOUT
D
16,383
= −VREF × n = −10 ×
= −10 V
2
16,384
Write Data 0x1000 (quarter scale) to the DAC. The output changes
its voltage from −10 V to −2.5 V, and the previous data written
to the part will appear on the SDO pin (in this example, −10 V).
VOUT = −VREF ×
D
16,383

To finish evaluating the part, push the STOP button.
To disable daisy-chain mode, check the Disable Daisy-chain
box in the Main Window after launching the application and
before clicking the OK button. The LED indicator with the
Daisy-chain Disabled label is lit, indicating the functionality
mode.
EXAMPLE 3
Select the AD5443 part from the Main Window and click the OK
button. The AD5443 Evaluation Software Window should appear.
Enter Data 0x800 (half scale) in the Input Data control and
select Load And Update. The output shows the expected −5 V value.
VOUT = −VREF ×
2,048
D
= −10 ×

Select Clear DAC Output To Zero Scale to get a voltage value
of 0 V on the output.
To put the part in three-quarter scale, write 0xBFD in the Input
Data control and select Load And Update.
VOUT = −VREF ×
3,069
D
= −10 ×
= −7.5 V
2n

To verify the data in the DAC register is correct, select Initiate
Readback and the indicator window beside this option shows
−7.5 V.
