Connect the negative terminal of the same power supply to the GND connector on the board. Required Equipment * MAX11105 EV kit * +5.5V, 500mA DC power supply 5) * Windows XP, Windows Vista, or Windows 7 PC with a spare USB port Set the signal source to generate a 100kHz, +1V peak-to-peak sinusoidal wave with +2V offset. 6) * Function generator Note: In the following sections, software-related items are identified by bolding. Text in bold refers to items directly from the EV kit software. Text in bold and underlined refers to items from the Windows operating system. Connect the positive terminal of the function generator to the AIN_DC or AIN_DC_SMA connector. Connect the negative terminal of the function generator to the GND connector. 7) Turn on the power supply. 8) Turn on the function generator. Procedure 9) Connect the USB cable from the PC to the EV kit board. Follow the instructions on the SLS_USB_ Driver_Help_100.pdf file to manually install the USB driver. Administrative privileges are required to install the USB device driver on Windows. The EV kit is fully assembled and tested. Follow the steps below to verify board operation. Caution: Do not turn on the power supply until all connections are completed. 1) Uncompress the 11105Rxx.ZIP file in a temporary folder. 2) Install the EV kit software on your computer by running the INSTALL.EXE program inside the temporary folder. The program files are copied to your PC and icons are created in the Windows All Programs menu. During software installation, some versions of Windows may show a warning message indicating that this software is from an unknown publisher. This is not an error condition and it is safe to proceed with installation. Administrator privileges are required to install the software on Windows. 3) 10) Start the EV kit software by opening its icon in the Windows All Programs menu. The EV kit software main window appears, as shown in Figure 1. 11) The main windows should display Hardware Connected in the bottom-left corner. 12) Check the Remove DC checkbox. 13) Press the Start Conversion button. 14) Verify that the Frequency displayed in the Calculation group box reads approximately 100000Hz. Verify that all jumpers are in their default positions, as shown in Table 1. 4 _______________________________________________________________________________________ MAX11105 Evaluation Kit Evaluates: MAX11105 Figure 1. MAX11105 EV Kit Software Main Window _______________________________________________________________________________________ 5 Evaluates: MAX11105 MAX11105 Evaluation Kit Detailed Description of Software The main window of the evaluation software (Figure 1) contains a Datalogging group box and four tabs to display the sampled data. Data Logging In the Datalogging group box, the user can select the desired number of conversions from the Number of Samples drop-down list. Enter the desired sampling rate in the Sample Rate (ksps) edit box. The actual sampling rate is displayed at the right of the Sample Rate (ksps) edit box. Press the Start Conversion button to start sampling. After sampling is finished, the user can save the data to a file by pressing the Save to File button. The Save to File button is not active until the sampling is done. Time Domain, Frequency Domain, Histogram, and Single Conversion Tabs After the Start Conversion button in the Datalogging group box is pressed, the sampled data in the time domain is plotted in the Time Domain tab sheet. The sampled data in the frequency domain is plotted in the Frequency Domain tab sheet and the histogram of the sampled signal is plotted in the Histogram tab sheet. The Single Conversion tab sheet displays one sampled data. Check the Auto Convert checkbox to automatically and repeatedly perform the ADC conversions and update the active tab sheet. Time Domain Tab In the Time Domain tab sheet (Figure 2), check the Remove DC checkbox to remove the DC component of the sampled signal. When the Auto Scale checkbox in the Scope Display Control Vertical group box is checked, the software automatically scales the vertical axis in the plot. If the Auto Scale checkbox is unchecked, enter the appropriate values into the Y-MAX and Y-MIN edit boxes and press the Set button to set the boundaries for the vertical axis. The software automatically calculates the Frequency, RMS, MIN, MAX, and Avg DC of the sampled signal and displays the calculated values in the Calculation group box. Frequency Domain Tab The Frequency Domain tab sheet (Figure 3) displays the FFT plot of the signal shown in the Time Domain tab sheet. Histogram Tab The Histogram tab sheet (Figure 4) displays the histogram of the signal shown in the Time Domain tab sheet. The software automatically calculates the Mean and the Std Dev (standard deviation, sigma) and displays the calculated values in the Calculation group box. The Histogram Display Control radio group box provides three options to scale the horizontal axis on the histogram: 1) (Mean - 3 sigma) to (Mean + 3 sigma) 2) (Mean - 6 sigma) to (Mean + 6 sigma) 3) User-defined range (MIN, MAX) Single Conversion The ADC Value Display group box in the Single Conversion tab sheet (Figure 5) displays the ADC Code and calculated Voltage values for a single sample. Press the Start Conversion button in the Datalogging group box to update the status of the ADC Value Display group box. 6 _______________________________________________________________________________________ MAX11105 Evaluation Kit Evaluates: MAX11105 Figure 2.

Single Conversion Tab 10 MAX11105 Evaluation Kit The MAX11105 EV kit is a fully assembled and tested PCB that evaluates the MAX11105 12-bit, SPI-compatible 2Msps ADC. The EV kit comes with a MAX11105AUT+ in a 6-pin SOT package installed. Power Supply A +5.5V power supply is required to power up the EV kit. Connect the positive terminal of the power supply to the VIN connector and the negative terminal to the GND connector. On-Board Input Buffer An on-board input buffer (U9) is provided on the EV kit. Connect the +5V, GND, and -5V terminals of the power supply to the OP+, GND, and OP- connectors, respectively, to power the on-board buffer. Move the shunt of JU18 to the 2-3 position and remove the shunts on JU19 and JU20. The user can connect the AC signal to the AIN_AC_SMA or the AIN_AC connector and connect the DC offset to the AIN_DC_SMA or the AIN_DC connector. If the measuring signal has already been shifted above the ground level, short the AC input to ground by installing a shunt on JU19, and connect the measuring signal to the AIN_DC_SMA or the AIN_DC connector. To bypass the buffer and connect the measuring signal directly to the AIN input of the ADC, move the shunt on JU18 to the 1-2 position. Finally, connect the measuring signal to the AIN_DC_SMA or the AIN_DC connector. User-Supplied SPI Interface For a user-supplied SPI interface, first move the shunts on JU12, JU13, and JU14 to the 2-3 position and connect the user-supplied CS, SCLK, and MISO signals to the corresponding CS, SCLK, and DOUT connectors on the EV kit.
