Evaluating the AD5142 Digital Potentiometer
FEATURES
GENERAL DESCRIPTION
Full featured evaluation board in conjunction with low
voltage digiPOT motherboard (EVAL-MB-LV-SDZ)
Various test circuits
Various ac/dc input signals
PC control via a separately purchased system demonstration
platform (SDP-B or SDP-S)
PC software for control
This user guide describes the evaluation board for evaluating the
AD5142—a quad-channel, 256-position, nonvolatile memory,
digital potentiometer. With versatile programmability, the AD5142
allows multiple modes of operation, including read/write access
in the RDAC and EEMEM registers, increment/decrement of
resistance, resistance changes in ±6 dB scales, wiper setting readback, and extra EEMEM for storing user-defined information,
such as memory data for other components or a lookup table.

Self-installing software that allows users to control the
board and exercise all functions of the device
Electronic version of the AD5142 data sheet
Electronic version of the UG-471 user guide
The AD5142 supports a dual-supply ±2.25 V to ±2.75 V operation
and a single-supply 2.3 V to 5.5 V operation, making the device
suitable for battery-powered applications and many other applications. In addition, the AD5142 uses a versatile SPI-compatible
serial interface, allowing speeds of up to 50 MHz. The EVALAD5142DBZ can operate in single-supply or dual-supply mode
and incorporates an internal power supply from the USB.
Complete specifications for the AD5142 part can be found in the
AD5142 data sheet, which is available from Analog Devices, Inc.,
and should be consulted in conjunction with this user guide
when using the evaluation board.

POWER SUPPLIES
The EVAL-MB-LV-SDZ motherboard supports using single and
dual power supplies.
The EVAL-AD5142DBZ evaluation board can be powered either
from the SDP port or externally by the J1 and J2 connectors, as
described in Table 1.
All supplies are decoupled to ground using 10 µF tantalum and
0.1 µF ceramic capacitors.

Several link and switch options are incorporated in the EVALMB-LV-SDZ motherboard and should be set up before using
the board. Table 2 describes the positions of the links to control

Linear Gain Setting Mode
The linear gain setting mode pin is controlled directly by
Jumper A1. If the jumper is placed in DEPEN, the AD5142
powers up in potentiometer mode, and the linear gain setting
mode can be controlled by software. If the jumper is placed in
INDEP, the part powers up in linear gain setting mode, loading
independent values for each resistor string—RAW1, RWB1, RAW2,
and RWB2. The part cannot be placed in potentiometer mode
again unless the jumper is manually placed in DEPEN.

TEST CIRCUITS
However, by using the R34 and R35 external resistors, the user
can reduce the voltage of the voltage references. In this case, use
the A1 and B1 test points to measure the voltage applied to the
A and B terminals and to recalculate VA and VB in Equation 1.
The EVAL-AD5142DBZ and EVAL-MB-LV-SDZ incorporate
several test circuits to evaluate the performance of the AD5142.

EVALUATION BOARD SOFTWARE
INSTALLING THE SOFTWARE
The EVAL-AD5142DBZ kit includes a CD containing the
evaluation board software. The software is compatible with
Windows® XP, Windows Vista, and Windows 7 (both 32 bits
and 64 bits).
2.
Install the software before connecting the SDP board to the USB
port of the PC to ensure that the SDP board is recognized when
it is connected to the PC.
Start > Control Panel > Add or Remove Programs >
AD5142 Eval Board.
If the SDP board is not connected to the USB port when
the software is launched, a connectivity error displays (see
Figure 8). Simply connect the evaluation board to the USB
port of the PC, wait a few seconds, click Rescan, and follow
the instructions.

5.
Start the Windows operating system and insert the CD into
the CD-ROM drive.
The installation software opens automatically. If it does not
open automatically, run the setup.exe file from the CD.
After the installation is complete, power up the evaluation
board as described in the Power Supplies section.
Connect the EVAL-AD5142DBZ and EVAL-MB-LV-SDZ
to the SDP board, and then connect the SDP board to the
PC using the USB cable included with the SDP board.
When the software detects the evaluation board, follow the
instructions that appear to finalize the installation.

buttons are available that allow you to change the level of some
hardware pins.
Manual Mode
The Manual Mode tab, as shown in Figure 10, allows you to
customize an I2C data-word by manually switching the scroll
bars from 0 to 1 or from 1 to 0, as desired, and then clicking
SEND DATA.
The INDIVIDUAL CHANNEL COMMANDS section allows
you to send quick commands to only specific channels of
the AD5142.
The block diagram allows you to update the control register
status. Each register value can be easily updated by changing the
