SERIAL INTERFACE POWER SUPPLIES The EVAL-AD7175-8SDZ evaluation board connects to the Blackfin(R) ADSP-BF527 on the SDP-B controller board via the serial peripheral interface (SPI). There are four primary signals, CS, SCLK, and DIN (all inputs), and one output from the ADC, DOUT/RDY. Power the evaluation board from the ac-to-dc adapter connected to J4, or from an external bench top supply applied to J3 or J5. Linear LDOs generate the required voltages from the applied input voltage (VIN) rail when using J3 or J4. Use J5 to bypass the on-board regulators. The regulators used are the 5 V fixed output voltage and 2.5 V adjustable output voltage ADP1720 devices, which supply the AVDD1 and AVDD2 rails to the ADC; the ADP1720 (3.3 V) supplies the IOVDD rail. Use the ADP7104 (5 V) to supply 5 V for the SDP-B controller board. Each supply is decoupled where it enters the board and again at each device. Table 3 shows the various power supply configurations available, including split supply operation. To operate the evaluation board in standalone mode, disconnect the AD7175-8 serial interface lines from the 120-pin header by removing the 0 , R9 through R13 links. Use the test points to connect the signals to an alternative digital capture setup. Rev. 0 | Page 5 of 10 UG-901 EVAL-AD7175-8SDZ User Guide Table 3.

Main Window of the AD7175-8 Evaluation Software OVERVIEW OF THE MAIN WINDOW Sampling The main window of the software displays the significant control buttons and analysis indicators of the AD7175-8 evaluation software (see Figure 7). This window is divided into four sections. The green numbers shown in Figure 7 (Label 1 through Label 4) correspond to the following components of the main window: Sampling (set to Capture in Figure 7) enacts the sampling mode used by the software. This is unrelated to the ADC mode. The user can capture a defined sample set or continuously gather batches of samples. In both cases, the number of samples set in the Samples numeric input dictates the number of samples. Click ADC Setup to open the ADC register map window. Use the new window to change register settings. This window allows the user to save existing register settings or load previously saved register settings. Control toolbar (Label 1)--control buttons Data section (Label 2)--waveform graph and controls Analysis section (Label 3)--histogram graph and controls Status bar (Label 4)--information ADC Setup CONTROL TOOLBAR ADC Reset Start Sampling and Samples Click ADC Reset to perform a software reset of the AD7175-8. There is no hardware reset pin. Perform a hard reset by removing power to the board. The software reset has the same effect as a hard reset. Start Sampling, located on the right of the control toolbar, gathers ADC results. Results appear in the graphs of the DATA and ANALYSIS sections of the main window. The Samples numeric control is the number of samples gathered per batch. Delete Data Clear Graphs Click Delete Data Clear Graphs to clear any existing content from the waveform and histogram graphs. Rev. 0 | Page 8 of 10 EVAL-AD7175-8SDZ User Guide UG-901 DATA SECTION ANALYSIS SECTION Data Waveform Analysis Histogram and Analysis Channel The data waveform shows each successive sample of the ADC output. The toolbar in the graph allows the user to zoom in on the data. Change the scales on the graph by typing values into the x-axis and y-axis. The histogram shows the analysis of the channel selected via the analysis channel drop-down box. This graph only shows the histogram for one channel at a time. Display Units Click Display Units to select whether the data graph displays in units of voltages or codes. This is the number of samples used for creating the histogram analysis. This is automatically set to equal the number of samples when Start Sampling is clicked. Vref Analysis Results Vref sets the reference voltage used for calculating the results on the data graph. The user must update this value when the reference source changes, because it does not automatically update. This section displays the results of the histogram analysis for the selected analysis channel. This includes both noise and resolution measurements. Autoscale STATUS Autoscale enables and disables the y-axis autoscale control for the data graph. With this control enabled, the graph automatically sets the maximum and minimum y-axis values to fit the displayed data. The status section at the bottom of the window display status updates such as Analysis Completed and Reset Completed during software use. X-scale and X-scale Samples EXITING THE SOFTWARE These controls set the number of data points displayed on the x-axis. When set to fixed, the number of data points is equal to the number in the X-scale Samples numeric input. This control automatically updates each time Start Sampling is clicked. When set to dynamic, all samples are displayed, including those from previous sample batches. To exit the software, click the close button at the top, right corner of the main window (see Figure 7). Channel Selection 1. 2. 3. This control allows the user to choose which channels display on the data waveform. It also shows the analog inputs for that channel labeled next to the on and off controls. These controls only affect the display of the channels and do not have any effect on the channel settings in the ADC register map. Latest Data Analyse Last # Samples SAVING RESULTS The software can save the current captured data for later analysis. 4. Right-click the waveform graph. Click Export in the drop-down menu. Select the folder for the data to be saved into and the name of the file you want to save. Click Save. The data is saved in the format selected for display units via the Display Units option.
