MAX11103 Evaluation Kit
General Description
The MAX11103 evaluation kit (EV kit) is a fully assem-
bled and tested PCB that evaluates the MAX11103
2-channel, 12-bit, SPI™-compatible 3Msps analog-
to-digital converter (ADC). The EV kit also includes
Windows XP
®
, Windows Vista
®
, and Windows
®
7-com-
patible software that provides a simple graphical user
interface (GUI) for exercising the features of the device.
The EV kit comes installed with a MAX11103AUB+ in a
10-pin
FMAX
®
package with an exposed pad.

MAX11103 EV kit
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. Administrator privileges are
required to install the USB device driver on Windows.
Required Equipment
5.5V, 500mA DC power supply
Windows XP, Windows Vista, or Windows 7 PC with
a spare USB port
Function generator
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 window should display
Hardware
Connected
at 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.
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.
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)
2)
Uncompress the 11103Rxx.ZIP file in a temporary
folder.
Install the EV kit software on your computer by run-
ning the INSTALL.EXE program inside the tempo-
rary 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 indicat-
ing that this software is from an unknown publisher.
This is not an error condition and it is safe to pro-
ceed with installation. Administrator privileges are
required to install the software on Windows.
Verify that all jumpers are in their default positions,
as shown in Table 1.
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.
Set the signal source to generate a 100kHz, 1V
peak-to-peak sinusoidal wave with 2V offset.
Connect the positive terminal of the signal gen-
erator to the AIN1_DC or AIN1_DC_SMA connector.
Connect the negative terminal of the signal genera-
tor to the GND connector.
Turn on the power supply.
Turn on the function generator.
Procedure
Detailed Description of Software
The main window of the evaluation software
(Figure 1) contains a
Device Configuration
group box,
a
Datalogging
group box, and four tab sheets to display
the sampled data.
Use the
Channel Select
drop-down list in the
Device
Configuration
group box to select the analog input
channel for analog-to-digital conversion.
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.

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.

Figure 1. MAX11103 EV Kit Software Main Window
The
Single Conversion
tab sheet displays one sampled
data.
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 (Figures 2a and 2b),
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 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.
