system.

Procedure

The EV kit is fully assembled and tested. Follow the

steps below to verify board operation. Caution: Do not

turn on power supplies until all connections are

completed.

1) Visit www.maxim-ic.com/evkitsoftware to down-

load the latest version of the EV kit software,

11040Rxx.ZIP. Save the EV kit software to a tempo-

rary folder and uncompress the ZIP file.

Make sure that the shunts of all jumpers are in the

default positions, as shown in Table 1.

3) Connect the analog voltage supply to the AVDD

and AGND connectors.

4) Connect the digital voltage supply to the DVDD and

DGND connectors.

5) Turn on the power supply.

6) Connect the negative terminal or ground terminal of

the signal source to the negative input (‘-’) on J3

(AIN0 on U1), and the positive terminal of the signal

source to the positive input (‘+’) on J3.

7) Set the signal source to generate a 60Hz, 2V peak-

to-peak sinusoidal wave.

8) Install the MAX11040 evaluation software on your

computer by running the INSTALL.EXE program

inside the temporary folder. The program files are

copied and icons are created for them in the

Windows Start | Programs menu.

9) Connect the USB cable from the PC to the EV kit. A

Building Driver Database window pops up in addi-

tion to a New Hardware Found message when

installing the USB driver for the first time. If a win-

dow that is similar to the one described above is not

seen after 30s, remove the USB cable from the EV

kit and reconnect it. Administrator privileges are

required to install the USB device driver on

Windows.

10) Follow the directions of the Add New Hardware

Wizard to install the USB device driver. Choose the

Search for the best driver for your device option.

Specify the location of the device driver to be

C:\Program Files\MAX11040 using the Browse

button. During device driver installation, Windows

may show a warning message indicating that the

device driver Maxim uses does not contain a digital

signature. This is not an error condition and it is

safe to proceed with installation. Refer to the

USB_Driver_Help.PDF document included with the

software for additional information.

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

Start | Programs menu.

12) Wait until the program automatically detects the

MAX11040 hardware and displays the user-inter-

face panel (Figure 1).

13) Press the Start Conversion button in the Data

Logging group box.

14) Press the Calculate button and verify that the

Frequency of 60Hz, the MIN value of -1V, and the

MAX value of 1V are displayed in the Calculation

group box.
