GENERAL DESCRIPTION

The AD5443, AD5446 and AD54531 are CMOS 12-, 14-, and
14-bit, 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 battery­powered 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.

EVAL-AD5443/AD5446/AD5453SDZ

Figure 1.

The applied external reference input voltage (V

) determines

REF

the full-scale output current. An integrated feedback resistor
(R

) provides temperature tracking and full-scale voltage output

FB

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 EVAL-AD5443SDZ/EVAL-AD5446SDZ/EVAL-AD5453SDZ
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

10226-002

INSTALLING THE SOFTWARE

The EVAL-AD5443SDZ/EVAL-AD5446SDZ/EVAL-AD5453SDZ
evaluation kit includes the software and drivers on CD. To install
the software, follow these steps:

1. Install the software before connecting the SDP board to the

USB port of the PC.

2. Start the Windows® operating system and insert the

EVAL-AD5443SDZ/EVAL-AD5446SDZ/EVAL-AD5453SDZ

evaluation kit CD.

3. Download the EVAL-AD5443SDZ/EVAL-AD5446SDZ/

EVAL-AD5453SDZ LabVIEW™ software. The correct driver,

SDPDriversNET, for the SDP board should download
automatically after LabVIEW is downloaded, supporting
both 32- 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.

4. After installation of the software and drivers is complete,

plug the EVAL-AD5443SDZ/EVAL-AD5446SDZ/EVAL-

AD5453SDZ into the SDP board and the SDP board into

the PC using the USB cable included in the box.

5. 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).

RUNNING THE SOFTWARE

To run the evaluation board program, do the following:

1. Click Start/All Programs/Analog Devices/EVAL-

AD5443SDZ/EVAL-AD5446SDZ/EVAL-AD5453SDZ).

2. 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.

USING THE EVALUATION BOARD SOFTWARE

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

Figure 4. Main Window

Figure 7. AD5453 Evaluation Software Window

EXAMPLE 1

Select the AD5453 part from the main window. Tick 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
light indicating the actual functionality mode (see Figure 5).

Enter Data 0x2000 (half scale) in the Input Data control and
click the Writ e 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.

appear. Enter Data 0x3FFF (full scale) in the Input Data control
and click the Wri te 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.

Write Data 0x1000 (quarter scale) to the DAC. The output changes
