A | Page 2 of 13 EVAL-AD5686RSDZ User Guide UG-725 EVALUATION BOARD HARDWARE POWER SUPPLIES LINK OPTIONS The EVAL-AD5686RSDZ provides an on-board, 3.3 V regulator powered through the USB supply. If a different supply is required or if the board is controlled through the PMOD, an external supply must be provided by the EXTSUP x connector. See Table 1 for more details. 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 Table 3. Both AGND and DGND inputs are provided on the board. The AGND and DGND planes are connected at one location close to the AD5686R. To avoid ground loop problems, it is recommended that AGND and DGND not be connected elsewhere in the system. All supplies are decoupled to ground with 10 µF tantalum and 0.1 µF ceramic capacitors. LDO RECOMMENDATION The ADP7118 low dropout (LDO) linear regulator (maximum VIN = 20 V) is recommended to power the VDD rail for maximal performance. A 4.7 Ω resistor in series with the input capacitor of the ADP7118 adds additional rejection at higher frequencies to reduce any power supply ripple artifacts below the noise floor. The ADP162 is recommended for powering the VLOGIC rail. Table 2 lists the positions of the different links controlled by the PC via the USB port. An SDP board operating in single-supply mode is required. VOLTAGE REFERENCES The AD5686R provides an internal voltage reference. The evaluation board provides external references with values of 2.5 V and 5 V. Note that the ADR3450 requires the use of an external supply through the EXTSUP x connector (see Table 3). TEST POINTS The evaluation board has various test points for debugging and monitoring purposes. These test points are described in Table 4. Table 1.

AD5686R Evaluation Software Main Window SOFTWARE OPERATION LDAC CONTROL The software for the AD5686R allows the user to program values to the input and DAC registers of each DAC individually or collectively. Within the HARDWARE LDAC PIN drop-down menu, select LDAC LOW to bring the LDAC pin low, and then select LDAC HIGH to return it to high. This action copies the data from the input registers to the DAC registers, updating the outputs accordingly. Write to Input Register Click Write to Input Register to load the value into the INPUT VALUE (HEX) box for the input register of any DACs selected in the DAC A, DAC B, DAC C, and DAC D boxes. Write to Input and DAC Register Click Write to Input and DAC Register to load the value into the input data control for the DAC registers selected in the DAC A, DAC B, DAC C, and DAC D boxes. The DAC outputs are updated automatically with the appropriate voltage. Update DAC Register from Input Register Click Update DAC Register from Input Register to copy the value in the DAC input register to the corresponding DAC register. DAC outputs are updated automatically with the appropriate voltage. GAIN Control The GPIO of the SDP sets the logic level of the GAIN pin and the software controls it. To display the correct voltage, set the gain selection to match the level of the GAIN pin. Select × 1 or × 2 from the GAIN drop-down menu to set the gain. Reference Control The AD5686R has an on-chip reference that can be disabled to reduce power consumption. Select Reference OFF from the REFERENCE drop-down menu to disable the on-chip reference. Power-Down Control Each of the DACs can be powered down individually. Each of the DACs has an associated POWER-DOWN DAC x drop-down menu that allows the device to operate in normal mode, be powered down with either a 1 kΩ or a 100 kΩ resistor to ground, or be three-stated. When power-down mode is selected, the software sends the appropriate command to the AD5686R and sets the appropriate channel to the selected power-down mode. Rev. A | Page 6 of 13 EVAL-AD5686RSDZ User Guide UG-725 LDAC Mask Register FULL SPI COMMAND When the LDAC MASK REGISTER boxes are checked, it forces the DAC channels to ignore transitions on the LDAC pin, regardless of the state of the hardware LDAC pin. The SPI commands sent to the DAC are displayed in the Full SPI Command box. This command is in hexadecimal format and shows what must be written to the AD5686R to replicate the function of the evaluation board if a different controller is used. Rev.
