4 / 10 page MAX5312 Evaluation Kit 4 _______________________________________________________________________________________ Use the DAC scrollbar to set the 12-bit DAC data. The adjacent label at the right of the scrollbar displays the equivalent expected output-voltage values of the DAC. Press the Load input register button to load the DAC data into the input register of the MAX5312 (DAC out- put unchanged). To load the input and DAC registers, press the Load input and DAC registers button (DAC output updated). To load the DAC register from the input register, press the Load DAC register from input register button (DAC output updated). Press the Enter Shutdown Mode button to put the MAX5312 into shutdown mode. To exit shutdown mode, press the Exit Shutdown Mode button. Hardware Control The Hardware Control group box controls the signals on the CLR, LDAC, UNI/BIP, and the SHDN pins through the GPIO pins of the microcontroller. By default, the signals on CLR, LDAC, and SHDN are high and the signal on UNI/ BIP is low. Press the Clear the input and DAC registers (/CLR) button to generate a negative pulse on the CLR pin and asynchronously clear the input and DAC registers. The DAC output is set to 0V in unipolar or bipolar mode. Press the Update the DAC register (/LDAC) button to generate a negative pulse on the LDAC pin and asyn- chronously load the DAC register from the input regis- ter. The DAC output immediately updates with the data from the input register. In the UNI//BIP group box, select the Bipolar Mode radio button to evaluate bipolar mode. Select the Unipolar Mode radio button to evaluate unipolar mode. In the /SHDN group box, select the Enter Shutdown Mode radio button to set the SHDN pin low to eval- uate the shutdown mode and reduce the current con- sumption. Select the Exit Shutdown Mode radio button to set the SHDN pin high and resume normal operation. Hardware control takes precedence over software control. SPI Interface Within the SPI Interface group box, the Status group box displays the last command that is sent to the MAX5312. Use the Send Command group box to manually enter the SPI command in hex format in the edit box and send the command to the MAX5312 by pressing the Send button. Detailed Description of Hardware The MAX5312 EV kit board provides a proven layout for evaluating the MAX5312. The EV kit comes with the MAX5312EAE+ installed. Voltage Reference By default, the on-board MAX6126 +5V external refer- ence is connected to the REF pin of the MAX5312. To use an external voltage reference, place the shunts of JU10 to the 2-3 position. Attach the external reference between +2V and +5.25V to the REF pad. Adjust the Voltage Reference values in the program. User-Supplied Signals To use the MAX5312 EV kit with an external SPI inter- face, install the shunts of JU1, JU4, JU5, and JU6 to the 2-3 position. Connect the SCLK, DIN, CS, DOUT, VCC, and GND lines from the external SPI interface to the corresponding pads on the MAX5312 EV kit. To apply the external signals to the SHDN and UNI/BIP pins of the MAX5312, install the shunts of JU2 and JU3 to the 2-3 position. Connect the external signals to the SHDN and UNI/BIP pads on the MAX5312 EV kit. Optimal Measurement To have the optimal measurements of the DAC output voltage, use an external power supply. After program- ming the output voltage for the DAC, disconnect the USB cable from the EV kit to eliminate any noise com- ing from the USB, and measure the output. |
