GENERAL DESCRIPTION
This user guide describes the evaluation board for evaluating the
AD5162,a dual-channel, 256-position digital potentiometer.
The AD5162 supports a single-supply 2.7 V to 5.5 V operation,
making the device suitable for battery-powered applications and
many other applications. In addition, the AD5162 uses a versa-
tile SPI-compatible serial interface, allowing speeds of up
to 25 MHz.
The EVAL-AD5162SDZ can operate in single-supply mode and
incorporates an internal power supply from the USB.
Complete specifications for the AD5162 part can be found in
the AD5162 data sheet, which is available from Analog Devices,
Inc., and should be consulted in conjunction with this user
guide when using the evaluation board.

EVALUATION BOARD HARDWARE
POWER SUPPLIES
The EVA L-AD5162SDZ supports using single power supplies.
The evaluation board can be powered either from the SDP-B
port or externally by the J1-1 and J1-2 connectors, as described
in Table 1.
All supplies are decoupled to ground using 10 µF tantalum and
0.1 µF ceramic capacitors.
Table 1. Maximum and Minimum Voltages of the Connectors
Connector No. Label Voltage
J1-1 EXT Analog positive power supply, VDD.
VDD For single-supply operation, it is 2.7 V
to 5 V.
J1-2 GND Analog ground.
LINK OPTIONS
Several link and switch options are incorporated in the
evaluation board and should be set up before using the board.
Tabl e 2 describes the positions of the links to control the
evaluation board by a PC, via the SDP-B board, using the EVA L -
AD5162SDZ in single-supply mode. The functions of these link
options are described in detail in Table 3 through Tabl e 6.

TEST CIRCUITS
The EVA L-AD5162SDZ incorporates several test circuits to
evaluate the AD5162 performance.
DAC
RDAC1 can be operated as a digital-to-analog converter (DAC),
as shown in Figure 2.
Figure 2. DAC
Tabl e 4 shows the options available for the voltage references.
Table 4. DAC Voltage References
Terminal Link Options Description
A1 A20 AC + DC Connects Terminal A1 to
(VDD − VSS)/2.
VDD Connects Terminal A1 to VDD.
W1 BUF_W1 Connects Terminal W1 to an
output buffer.
B1 A21 DC Connects Terminal B1 to
(VDD − VSS)/2.
GND Connects Terminal B1 to
analog ground.
The output voltage is defined in Equation 1.

where:
RWB1 is the resistor between the W1 and B1 terminals.
VA1 is the voltage applied to the A1 terminal (A20 link).
VB1 is the voltage applied to the B1 terminal (A21 link).
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
A0 and B0 terminals and recalculate VA0 and VB0 in Equation 1.
AC Signal Attenuation
RDAC1 can be used to attenuate an ac signal, which must be
provided externally using the AC_INPUT connector, as shown
in Figure 3.
Figure 3. AC Signal Attenuator
Depending on the voltage supply rails and the dc offset voltage
of the ac signal, various configurations can be used as described
in Tabl e 5.
Table 5. AC Signal Attenuation Link Options
Link Options Conditions
A20 AC + DC No dc offset voltage.
AC signal is outside the voltage supply rails
due to the dc offset voltage.
DC offset voltage ≠ VDD/2.1
AC All other conditions.
A21 DC Use in conjunction with ac + dc link.
GND All other conditions.
1Recommended to ensure optimal total harmonic distortion (THD) performance.

In addition, R36 can be used to achieve a pseudologarithmic
attenuation. To do so, adjust the R36 resistor until a desirable
transfer function is found.

Signal Amplifier
RDAC2 can be operated as an inverting or noninverting signal
amplifier supporting linear or pseudologarithmic gains. Tabl e 6
shows the available configurations.

EVALUATION BOARD SOFTWARE
INSTALLING THE SOFTWARE
The EVA L-AD5162SDZ evaluation kit includes evaluation
board software provided on a CD. The software is compatible
with Windows® XP, Windows Vista, and Windows 7 (both
32 bits and 64 bits).
Install the software before connecting the SDP-B board to the USB
port of the PC to ensure that the SDP-B board is recognized
when it is connected to the PC.
1. Start the Windows operating system and insert the CD.
2. The installation software opens automatically. If it does
not, run the setup.exe file from the CD.
3. After installation is completed, power up the evaluation
board as described in the Power Supplies section.
4. Connect the E VA L -AD5162SDZ to the SDP-B board and the
SDP-B board to the PC using the USB cable included in the
evaluation kit.
5. When the software detects the evaluation board, follow the
instructions that appear to finalize the installation.
To uninstall the program, click Start > Control Panel >
Add or Remove Programs > AD5162 Eval Board.
RUNNING THE SOFTWARE
To run the program, do the following:
1. Click Start > All Programs > Analog Devices > AD5162 >
AD5162 Eval Board.
2. If the SDP-B board is not connected to the USB port when
the software is launched, a connectivity error displays (see
Figure 6). Simply connect the evaluation board to the USB
port of the PC, wait a few seconds, click Rescan, and follow
the instructions.
Figure 6. Pop-Up Window Error
The main window of the E VAL -AD5162SDZ evaluation
software then opens, as shown in Figure 7.

SOFTWARE OPERATION
The main window of the E VA L -AD5162SDZ software is
divided into the following sections: RDAC1, RDAC2, and
REGISTER ACCESS.
RDAC1 and RDAC2 can be used to update the RDAC registers
by entering a desirable value into the text box and clicking
WRITE.
REGISTER ACCESS has the following options:
•SEND DATA is a customized I2C data-word that can be
sent by manually switching the scroll bars from 0 to 1 or
from 1 to 0, as desired, and then clicking SEND DATA.
In addition, the scroll bars are updated on each write
transfer, showing the command sent to the part.
•Clicking EXIT closes the program but does not reset the part.

NOTES
I2C refers to a communications protocol originally developed by Philips Semiconductors (now NXP Semiconductors).
ESD Caution
ESD (electrostatic discharge) sensitive device. Charged devices and circuit boards can discharge without detection. Although this product features patented or proprietary protection
circuitry, damage may occur on devices subjected to high energy ESD. Therefore, proper ESD precautions should be taken to avoid performance degradation or loss of functionality.
Legal Terms and Conditions
By using the evaluation board discussed herein (together with any tools, components documentation or support materials, the “Evaluation Board”), you are agreeing to be bound by the terms and conditions
set forth below (“Agreement”) unless you have purchased the Evaluation Board, in which case the Analog Devices Standard Terms and Conditions of Sale shall govern. Do not use the Evaluation Board until you
have read and agreed to the Agreement. Your use of the Evaluation Board shall signify your acceptance of the Agreement. This Agreement is made by and between you (“Customer”) and Analog Devices, Inc.
(“ADI”), with its principal place of business at One Technology Way, Norwood, MA 02062, USA. Subject to the terms and conditions of the Agreement, ADI hereby grants to Customer a free, limited, personal,
temporary, non-exclusive, non-sublicensable, non-transferable license to use the Evaluation Board FOR EVALUATION PURPOSES ONLY. Customer understands and agrees that the Evaluation Board is provided

“Third Party” includes any entity other than ADI, Customer, their employees, affiliates and in-house consultants. The Evaluation Board is NOT sold to Customer; all rights not expressly granted herein, including
ownership of the Evaluation Board, are reserved by ADI. CONFIDENTIALITY. This Agreement and the Evaluation Board shall all be considered the confidential and proprietary information of ADI. Customer may
not disclose or transfer any portion of the Evaluation Board to any other party for any reason. Upon discontinuation of use of the Evaluation Board or termination of this Agreement, Customer agrees to
promptly return the Evaluation Board to ADI. ADDITIONAL RESTRICTIONS. Customer may not disassemble, decompile or reverse engineer chips on the Evaluation Board. Customer shall inform ADI of any
occurred damages or any modifications or alterations it makes to the Evaluation Board, including but not limited to soldering or any other activity that affects the material content of the Evaluation Board.
Modifications to the Evaluation Board must comply with applicable law, including but not limited to the RoHS Directive. TERMINATION. ADI may terminate this Agreement at any time upon giving written notice
to Customer. Customer agrees to return to ADI the Evaluation Board at that time. LIMITATION OF LIABILITY. THE EVALUATION BOARD PROVIDED HEREUNDER IS PROVIDED “AS IS” AND ADI MAKES NO
