Quick Start
Required Equipment
• MAX11105 EV kit
• +5.5V, 500mA DC power supply
• Windows XP, Windows Vista, or Windows 7 PC with
a spare USB port
• 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 under-
lined refers to items from the Windows operating system.
Procedure
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) Verify that all jumpers are in their default positions,
as shown in Table 1.
4) Connect the positive terminal of the +5.5V power
supply to the VIN connector on the board. Connect
the negative terminal of the same power supply to
the GND connector on the board.
5) Set the signal source to generate a 100kHz, +1V
peak-to-peak sinusoidal wave with +2V offset.
6) 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.
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.
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.

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 check-
box 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 automati-
cally calculates the Frequency, RMS, MIN, MAX, and
Avg DC of the sampled signal and displays the calcu-
lated 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.

Detailed Description of Hardware
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 con-
nector 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 con-
nect the user-supplied CS, SCLK, and MISO signals to
the corresponding CS, SCLK, and DOUT connectors on
the EV kit.
