GENERAL DESCRIPTION This user guide describes the evaluation board for evaluating the ADN2850—a dual-channel, 1024-position, nonvolatile memory digital resistor. With versatile programmability, the ADN2850 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 read-back, and extra EEMEM for storing user-defined information, such as memory data for other components or a lookup table.
The ADN2850 supports a dual-supply ±2.25 V to ±2.75 V operation and a single-supply 2.7 V to 5.5 V operation, making the device suited for battery-powered applications and many other applications. In addition, the ADN2850 uses a versatile SPI-compatible serial interface, allowing speeds of up to 50 MHz.
The EVAL-ADN2850SDZ can operate in single-supply and dual-supply mode and incorporates an internal power supply from the USB.
Complete specifications for the ADN2850 part can be found in the ADN2850 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 EVAL-ADN2850SDZ supports the use of single and dual power supplies.
In single-supply mode, the evaluation board can be powered either from the SDP port or externally by the J1-1, J1-2, and J1-3 connectors, as described in Table 1.
If dual-supply mode is required, the J1-1, J1-2, and J1-3 connectors must provide the external power supply, 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 VDD Analog positive power supply, VDD. For single-supply operation, it is
2.7 V to 5.5 V. For dual-supply operation, it is
2.5 V to 2.75 V. J1-2 GND Analog GND. J1-3 EXT VSS Analog negative power supply, VSS. For single-supply operation, it is 0 V. For dual-supply operation, it is
−2.5 V to −2.75 V.
LINK OPTIONS Several link and switch options are incorporated in the evalu-ation board and should be set up before using the board. Table 2 describes the positions of the links to control the evaluation board by a PC, via the SDP board, using the EVAL-ADN2850SDZ in single-supply mode. The functions of these link and switch options are described in detail in Table 3 through Table 6.
Table 2. Link Options Setup for SDP Control (Default) Link No. Option A25 3.3 V A24 GND
Table 3. Link Functions Link No. Power Supply Options A25 VDD This link selects one of the following as the positive power supply: 5 V (from SDP). 3.3 V (from SDP). EXT (external supply from the J1-1 connector). A24 VSS This link selects one of the following as the negative power supply: GND (analog ground). VSS (external supply from the J1-3 connector).

EVALUATION BOARD SOFTWARE INSTALLING THE SOFTWARE The EVAL-ADN2850SDZ evaluation kit includes evaluation board software provided on a CD. The software is compatible with Windows® XP, Windows Vista, and Windows 7 (both 32 and 64 bits).
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.
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. Plug the EVAL-ADN2850SDZ 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, follow the instructions that appear to finalize the installation.
To uninstall the program, click Start > Control Panel > Add or Remove Programs > ADN2850 Eval Board.
RUNNING THE SOFTWARE To run the evaluation board software, do the following:
1. Click Start > All Programs > Analog Devices > ADN2850 > ADN2850 Eval Board.
2. If the SDP board is not connected to the USB port when the software is launched, a connectivity error is displayed (see Figure 9). Connect the evaluation board to the USB port of the PC, wait a few seconds, click Rescan, and follow the instructions.

SOFTWARE OPERATION The main window of the EVAL-ADN2850SDZ software is divided into the following sections: QUICK COMMANDS, REGISTER ACCESS, HARDWARE PINS, TOLERANCE, and MEMORY. The features of the main window are as follows:
• The QUICK COMMANDS section allows you to send the ADN2850 quick commands directly to the ADN2850.
• The REGISTER ACCESS section can be used to update the RDAC registers by typing a value into a window and clicking WRITE. Alternatively, you can send a customized SPI data word by manually switching the scroll bars from 0 to 1 or from 1 to 0, as desired, and then clicking SEND DATA. When WRITE is clicked or a quick command is executed, a write-read operation is performed, and the values displayed in this section are updated with the actual
RDAC register values. This function can be used to verify whether the write operation was completed successfully. The scroll bars are updated upon each write transfer.
• The HARDWARE PINS section selects the level of the external control pins, switches the level of the WP pin, and generates a pulse in the PR pin.
• The TOLERANCE section displays the stored tolerance of the RDAC1 internal resistor.
• The MEMORY section displays the data stored in the memory block. The data can be updated by switching the scroll bar from READ to WRITE, updating a particular window value, clicking UPDATE ALL or UPDATE SINGLE, and selecting the memory location to write.
• Clicking EXIT closes the program but does not reset the part.

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 WARRANTIES OR REPRESENTATIONS OF ANY KIND WITH RESPECT TO IT.
