The EV kit software main window appears, as shown in Figure. ) The main window should display Hardware Connected at the bottom-left corner ) Check the Remove DC checkbox. ) Press the Start Conversion button. 6) Verify that the Frequency displayed in the Calculation group box reads approximately 00000Hz. Detailed Description of Software The main window of the evaluation software (Figure ) contains a Device Configuration group box, a Datalogging group box, and four tab sheets to display the sampled data. Device Configuration Use the Channel Select drop-down list in the Device Configuration group box to select the analog input channel for analog-to-digital conversion. Data Logging In the Datalogging group box, the user can select the desired number of conversions in 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. Maxim Integrated

Check the Auto Convert checkbox to automatically and repeatedly do the ADC conversions and update the active tab sheet. Time Domain Tab In the Time Domain tab sheet (Figure a and b), check the Remove DC check box to remove the DC component of the sampled signal. In the Scope Display Control Vertical group box, when the Auto Scale checkbox 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 ) displays the FFT plot of the signal shown in the Time Domain tab sheet. Maxim Integrated

9 MAX9777 Evaluation System Evaluates: MAX9777 Detailed Description of Hardware The MAX9777 EV kit is a fully assembled and tested PCB that evaluates the MAX9777 -channel, -bit, SPI-compatible Msps ADC. The EV kit comes installed with a MAX9777AZA+ in a 8-pin WLP package. Power Supplies A +.V power supply is required to power up the MAXPRECADCMB. Connect the positive terminal of the power supply to the VIN connector and the negative terminal to the GND connector. +V power supply is required to power up the +.0V reference to supply the MAX9777. On-Board Input Buffer On-board input buffers (U9_XXXX) are provided on the EV kit. To power the on-board buffers, connect the +V, GND, and -V terminals of the power supply to the OP+, GND, and OP- connectors, respectively. Analog Input Move the shunt on jumper J8_UA to the - position and remove the shunts on jumpers J9_UA and J0_UA. The user can connect the DC signal to the U_AIN_ DC_SMA or U_AIN_AC connector and connect the DC offset to the U_AIN_DC_SMA or U_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 J9_UA and connecting the measuring signal to the U_AIN_DC_SMA or U_AIN_ DC connector. To bypass the buffer and connect the measuring signal directly to the AIN input of the ADC, remove the shunt on J_UA. Then connect the measuring signal to the U_AIN connector. Analog Input Move the shunt on jumper J8_UB to the - position and remove the shunts on jumpers J9_UB and J0_UB. The user can connect the AC signal to the U_AIN_AC_SMA or U_AIN_AC connector and connect the DC offset to the U_AIN_DC_SMA or U_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 JU and connect the measuring signal to the U_AIN_DC_SMA or U_AIN_DC connector. To bypass the buffer and connect the measuring signal directly to the AIN input of the ADC, remove the shunt on J8_UB. Finally, connect the measuring signal to the U_AIN connector. User-Supplied SPI Interface For user-supplied SPI, the user must remove the shunts on headers J8 to J. The use can apply the usersupplied SPI signals to pin of header J8 to J, respectively. Make sure return ground is connected to the MAX9777 EV kit. Table. Jumper Settings JUMPER SHUNT POSITION DESCRIPTION J J_U J_BB J J Connects V+ and OP+ together.
