driver. Administrator privileges are required to install

the USB device driver on Windows.

7) Start the EV kit software by opening its icon in the

Windows All Programs menu.

8) Press the Start Conversion button.

9) From the Device Configuration tab sheet, select

0110 UPPER_EXT from the SCAN drop-down list.

10) Select the Data Analysis tab sheet.

11) Press the Start Conversion button.

12) Observe the scope image (as shown in Figure 1) and

verify the data sampled is valid.

Precision Quick Start

Required Equipment

+5V, 750mA DC power supply

5V, 100mA 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-

line 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) Visit www.maxim-ic.com/evkitsoftware to download

the latest version of the EV kit software, 11131Rxx.Zip.

Save the EV kit software to a temporary folder and

uncompress the zip file.

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

Start | Programs menu. During software installa-

tion, 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 USB device

driver on Windows.

3) Verify that all jumpers are in their default positions, as

shown in Table 1.

4) Move the shunt on jumper JU17 to the 1-4 position.

5) Connect the +5V DC power supply to the VIN and

GND test points.

6) On the Q5V DC power supply, connect the +5V ter-

minal to the OP+ test point, the -5V terminal to the

OP- test point, and the ground terminal to the nearest

GND test point.

7) Set the function generator to generate a 500kHz,

+2.4V peak-to-peak sinusoidal wave with +1.2V

offset.

8) Connect the positive terminal of the function

generator to the AIN0+_SMA connector or AIN0+

test point. Connect the negative terminal of the func-

tion generator to the GND test point.

9) Turn on the power supplies.

10) Enable the function generator.

11) 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.

12) Start the EV kit software by opening its icon in the

Windows All Programs menu.

13) Select the Data Analysis tab sheet.

14) Press the Start Conversion button.

15) Verify the RMS value of approximately 1.47V, the

MIN of 0V, MAX of 2.4V, and the Avg DC of 1.2V are

displayed in the Calculation group box.

Detailed Description of Software

The MAX11131 EV kit software main window (Figure

2) contains a Device Configuration tab and a Data

Analysis tab to display the sampled data.
