Quick Start
Required Equipment
Before beginning, the following equipment is needed:
? MAX9694 EV kit (USB cable included)
? A user-supplied Windows 2000/XP- or Windows
Vista-compatible PC with a spare USB port
DESCRIPTION
Installs the EV kit files on your computer
Application program
Software Initialization File
USB device driver file
Uninstalls the EV kit software
USB driver installation help file
Search for the best driver for your device option.
Specify the location of the device driver to be
C:\Program Files\MAX9694 (default installation
directory) 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 instal-
?
?
9V to 20V DC power supply @ 500mA
One digital voltmeter (DVM)
lation. Refer to the USB_Driver_Help.PDF document
included with the software for additional information.
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
underlined refers to items from the Windows operating
system.
Procedure
The MAX9694 EV kit is fully assembled and tested.
Follow the steps below to verify board operation:
1) Visit www.maxim-ic.com/evkitsoftware to down-
load the latest version of the EV kit software,
9694Rxx.ZIP. Save the EV kit software to a tempo-
rary folder and uncompress the ZIP file.
2) 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 and icons
are created in the Windows Start | Programs
menu.
3) Connect the USB cable from the PC to the EV kit
board. A New Hardware Found window pops up
when installing the USB driver for the first time. If
you do not see a window that is similar to the one
described above after 30 seconds, remove the USB
cable from the board and reconnect it.
Administrator privileges are required to install the
USB device driver on Windows.
4) Follow the directions of the Add New Hardware
Wizard to install the USB device driver. Choose the
5) Once the software and hardware installation is com-
plete, disconnect the USB cable from the EV kit.
6) Verify that shunts are installed as follows:
JU1: Pins 1-2 (on-board 3.3V digital power supply)
JU2: Pins 1-2 (MAX9694 write address = 0xE8)
7) Connect the USB cable to the EV kit.
8) Connect the DVM negative terminal to the AGND
PCB pad next to the VREFL_L PCB pad.
9) Connect a voltage probe to the DVM positive termi-
nal for later use.
10) Set the power supply to 15V and disable the power-
supply output.
11) Connect the power-supply positive terminal to the
AVDD PCB pad (center of board) and the negative
terminal to the nearby AGND PCB pad.
12) Enable the power-supply output.
13) Start the MAX9694 EV kit software by opening its
icon in the Start | Programs menu. The EV kit soft-
ware main window appears, as shown in Figure 1.
14) Use the DVM voltage probe to measure the refer-
ence input voltages on the VREFU_H, VREFU_L,
VREFL_H, and VREFL_L PCB pads, and type those
values into the corresponding edit boxes of the
Reference Voltages (V) group box in the software.
