The device is specified to operate from single supply voltages from 4.75 V up to 30 V, or dual supply voltages from −16.5 V to 0 V (VSS) and +4.75 V to +16.5 V (VDD). The nominal full-scale output range is software or hardware selectable. The integrated output amplifiers, reference buffers, and power-up/power-down control circuitry provide an easy to use, universal solution. EVALUATION BOARD DESCRIPTION The EVAL-AD5761RSDZ is a full featured evaluation board that allows the user to easily evaluate all the features of the AD5761R 16-bit, voltage output digital-to-analog converter (DAC). The AD5761R pins are accessible at on-board connectors for external connection. The evaluation board can be controlled by two means: via the on-board connector (J3), or via the SDP connector (J4). The EVAL-SDP-CB1Z SDP board allows the evaluation board to be controlled through the USB port of a Windows® XP (SP2 or later) or Windows Vista (32-bit) based PC using the AD5761R evaluation software. Complete specifications for the AD5761R are available in the AD5761R data sheet, which should be consulted in conjunction with this user guide when using this evaluation board.

Connector J3 Pin Configuration • 9 10 • • 3.3 V between the VCC and DGND inputs for the digital supply of the AD5761R. Alternatively, place Link LK1 in Position A to power the digital circuitry from the USB port (default). 4.75 V to 28 V between the VDD and AGND inputs for the positive analog supply of the AD5761R. −4.5 V to −16.5 V between the VSS and AGND inputs for the negative analog supply of the AD5761R. The analog and digital planes are connected at one location close to the AD5761R. To avoid ground loop problems, do not connect AGND and DGND elsewhere in the system. Each supply is decoupled to the relevant ground plane with 10 µF and 0.1 µF capacitors. Each device supply pin is again decoupled with a 10 µF and 0.1 µF capacitor pair to the relevant ground plane. 7 8 5 6 3 4 1 2 Table 3.

The evaluation software is compatible with Windows XP (SP2 or later) and Windows Vista (32-bit). If the setup file does not run automatically, run setup.exe from the CD. To launch the evaluation software, complete the following steps: Install the evaluation software before connecting the evaluation board and SDP board to the USB port of the PC to ensure that the evaluation system is correctly recognized when connected to the PC. 2. 2. After installation from the CD is complete, power up the EVAL-AD5761RSDZ evaluation board as described in the Power Supplies section. Connect the SDP board (Connector A) to the evaluation board and then to the USB port of your PC using the supplied cable. When the evaluation system is detected, proceed through any dialog boxes that appear to complete the installation. From the Start menu, click Analog Devices > AD5761R > AD5761R Evaluation Software. The main window of the software opens (see Figure 5). If the evaluation system is not connected to the USB port when the software is launched, a connectivity error displays (see Figure 2). Connect the evaluation board to the USB port of the PC, wait a few seconds, and click Rescan. Follow the instructions that appear. 12572-002 1. 1. Figure 2. Connectivity Error Alert Rev. 0 | Page 4 of 11 EVAL-AD5761RSDZ User Guide UG-751 MAIN WINDOW The main window of the evaluation software is divided into two tabs: Configure and DAC. 12572-103 Begin by choosing the device to evaluate: the AD5761R (16-bit resolution) or the AD5721R (12-bit resolution). Note that clicking the AD5721R option allows the user to evaluate the AD5761R as a 12-bit DAC; there is no separate evaluation setup for the AD5721R. A dialog box appears for this selection, as shown in Figure 3. The AD5761R requires an initial command to write to the control register to remove the output clamp to ground. A dialog box appears as a reminder to write to the control register (see Figure 4). During the same write, configure the AD5761R as necessary to modify the default values for the power-up voltage (Power Up Voltage), voltage output range (Output Range), clear voltage (CLEAR Voltage), overrange (OVR), bipolar range coding (B2C), thermal shutdown alter (ETS), and internal reference mode (IRO). 12572-003 Figure 3.
