Full data on the AD5593R can be found in the AD5593R data sheet, available from Analog Devices and should be consulted in conjunction with this user guide when using the evaluation board. The evaluation board is designed to help customers quickly prototype new AD5593R circuits and reduce design time. The AD5593R operates from a single 2.7 V to 5.5 V supply and incorporates an internal 2.5 V reference to give an output voltage span of 2.5 V or 5 V. An external reference (a 2.5 V reference is provided on the evaluation board) can also be used to give an output from 0 V to VREF or 0 V to 2 × VREF. The evaluation board interfaces to the USB port of a PC via the SDP board. Software is supplied with the evaluation board to allow the user to program the AD5593R. This evaluation board requires the EVAL-SDP-CB1Z board (SDP-B controller board), which is available for order on the Analog Devices website at www.analog.com.

The software is compatible with Windows® XP, Windows Vista (32-bit version), and Windows 7 (32- and 64-bit versions). The software must be installed 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. 4. To install the software, take the following steps: 1. 2. Start the Windows operating system and insert the CD. The installation software should open automatically. If it does not open automatically, run the setup.exe file from the CD. 5. After installation is completed, power up the evaluation board as described in the Power Supplies section. Connect the evaluation board to the SDP board and connect 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. EVALUATION BOARD SETUP PROCEDURES 1. 2. Rev. 0 | Page 4 of 14 Connect the evaluation board to the SDP board, and connect the USB cable between the SDP board and the PC. Power the SDP and evaluation boards by connecting 6 V to the J3 connector. EVAL-AD5593RSDZ User Guide UG-756 EVALUATION BOARD HARDWARE POWER SUPPLIES DIGITAL INPUT AND OUTPUT SIGNALS To use the evaluation board with the SDP board, a 6 V power supply is required, which is connected to Connector J3. The evaluation board can also be used without the SDP board. In this case, J2 is the power supply input for the VDD supply. A separate VLOGIC supply can be connected to J1 if required. LK11 selects the source for the AD5593R VLOGIC supply. When the SDP board is used to control the AD5593R evaluation board, the digital input signals are applied to Connector J4. When the SDP board is not being used, digital signals should be applied to the 10-way header, J5.

When the board is shipped, it is assumed that you are going to operate the evaluation board with the SDP board (SDP controlled mode). A number of link options are incorporated in the evaluation board and must be set for the required operating conditions before using the board. The functions of these link options are described in detail in Table 2. SETUP CONDITIONS Take care before applying power and signals to the evaluation board to ensure that all link positions are as required by the operating mode. There are two modes in which to operate the evaluation board. The evaluation board can be operated in SDP controlled mode to be used with the SDP board, or the evaluation board can be used in standalone mode. Table 2. Link Functions Link Number LK1 LK2, LK4 to LK9, LK20 LK3 LK11 Option This link selects the VDD source for the AD5593R. Position A selects the internal voltage source (5V_VDD) from the ADP3331. Position B selects an external supply voltage (EXT_VDD). These links connect a 100 kΩ pull-down resistor from the I/Ox pins to AGND. When a link is removed, the level of associated pin is determined by the configuration of the AD5593R. This link selects the reference source for the AD5593R. Position A selects the on-board 2.5 V reference as the reference source. Position B selects an off board voltage reference via the EXT_REF connector. This option should also be selected if the internal reference is to be used. This link selects the source of the VLOGIC supply for the AD5593R. Position A selects the 3.3 V supply from the SDP board. Position B selects the VLOGIC supply from Connector J1. Position C selects the VDD supply determined by LK1.

The evaluation board contains two voltage regulators, which generate the analog and digital power supplies and also power the SDP board if it is connected. The two regulators are powered via a 6 V supply attached to Connector J3. Alternatively, a separate supply can be attached via Connector J2. An optional VLOGIC supply can be connected to J1 if required. Control of the AD5593R is typically performed by the SDP board, which is attached to J4. The SDP board allows the software provided with the kit to be to used configure the AD5593R and write/read data to/from the AD5593R. When the SDP is not required, the control signals can be applied to the AD5593R by connecting them to the relevant pins on Connector J5. In addition to the on-chip reference of the AD5593R an external, 2.5 V reference is also provided and can be connected to the AD5593R reference input/output pin (VREF) using LK3.
