Procedure
Please visit the Maxim Integrated Products website
(www.maxim-ic.com) to download the most recent ver-
sion of the EV kit software 9590RXX.ZIP. The MAX9590
EV kit is fully assembled and tested. Follow these steps
to verify board operation. Do not turn on the power sup-
ply until all connections are completed.
1) Set jumper JU1 on the CMAXQUSB at 3.3V or 5V output.
2) Set DIP switch SW1 on the CMAXQUSB to the ON
position (SCL and SDA line pullup resistors
enabled).
3) Set the jumpers on the MAX9590EVKIT as follows:
JU1: pins 1-2 (EV kit powered by CMAXQUSB)
JU2: pins 1-2 (default I2C write address is 0xE8)
4) Connect the MAX9590 EV kit 2 x 10-pin receptacle
(J1) to the CMAXQUSB 2 x 10-pin header (P3).
5) Connect the 9V to 16.5V DC power supply to the
AVDD and AGND pads on the EV kit and turn on
the power supply.
6) Install the MAX9590 evaluation software on your
computer by running the INSTALL.EXE program. The
program files are copied and icons are created for
them in the Windows Start menu | All Programs |
Maxim MAX9590 Evaluation Kit by default.
7) Connect the USB cable between the PC’s USB port
and the CMAXQUSB’s USB connector (P2). A New
Hardware Found window should pop up. If you do not
see this window after about 30 seconds, try removing
the USB cable from the CMAXQUSB and reconnect it.
Administrator privileges are required to install the
USB device driver on Windows 2000 and Windows
XP. Refer to the TROUBLESHOOTING_USB.PDF file
if problems are experienced during this step.
8) 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\MAX9590 (or the directory cho-
sen during installation) using the Browse button.
9) Start the MAX9590 EV kit software by opening its
icon in the Start | All Programs | Maxim MAX9590
Evaluation Kit.
10) The program automatically detects the MAX9590
address and displays it on the bottom of the win-
dow. By default, the software sets the MAX9590 in
Standard operation mode and selects bank A to be
buffered to the output.
11) Measure the voltages on the VREFU_H, VREFU_L,
VREFL_H, VREFL_L pads, and type the values in
MAX9590 Evaluation Kit/Evaluation System
