FTD2XX.INF
Application program
MAX5535 EV kit help file
USB device driver file
1) Visit www.maxim-ic.com/evkitsoftware to download
the latest version of the EV kit software,
5535Rxx.ZIP. Save the EV kit software to a tempo-
rary folder and uncompress the ZIP file.
UNINST.INI
Uninstalls the EV kit software
2) Install the EV kit software on your computer by run-
ning the INSTALL.EXE program inside the temporary
folder. The program files are copied and icons are
created in the Windows Start | Programs menu.

3) Verify that all jumpers (JU1–JU6) are in their default
positions, as shown in Table 1.
7) 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\MAX5535 (default installation
directory) using the Browse button.
4) To measure OUTA, connect the first DVM between
H2-1 (OUTA) and H2-2 (GND).
5) To measure OUTB, connect the second DVM
between H2-3 (OUTA) and H2-4 (GND).
8) Start the MAX5535 EV kit software by opening its
icon in the Start | Programs menu. The EV kit soft-
ware main window should appear, as shown in
Figure 1.
6) Connect the USB cable from the PC to the EV kit
board. A Building Driver Database window pops
up in addition to a New Hardware Found mes-
sage 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 30s, remove the
USB cable from the board and reconnect it.
Administrator privileges are required to install the
USB device driver on Windows 2000 and XP.
Refer to the TROUBLESHOOTING_USB.PDF docu-
ment included with the software if any problems
arise during this step.
9) Enter 0xD2E into the D11 - D0 (Shift Register Data
Bits) edit box.
10) Press the lower Load DAC A and DAC B button
located at the bottom of the EV kit software main
window. This loads input and output DAC registers
from the shift register.
11) Verify that the voltage shown on both DVMs is
approximately 1V.

Figure 1. MAX5535 EV Kit Software Main Window (Load DACs Tab)
Detailed Description of Software
Detailed Description of Hardware
The main window of the evaluation software (shown in
Figure 1) displays the voltage and code for all DAC
input and output registers. In addition, the main window
has two tabs. The Load DACs tab sheet controls all the
DAC loading features of the MAX5535 family. The
Operating Modes tab sheet (shown in Figure 2) con-
trols all the DAC modes of the MAX5535 family. The
Load Setting(s) button must be pressed in order to
write the operating mode settings to the DAC(s).
The MAX5535 EV kit provides a proven layout for the
MAX5535. An on-board reference, level translators,
SPI-interface pads, and easy-to-use USB-PC connec-
tion are included on the EV kit.
Reference
Measure REFOUT at pin 2 of JU5 for all internal refer-
ence parts. Enter the value of the internal reference
voltage into the Set Vref edit box in the software GUI.
For external reference parts, connect a 0V to VDD
reference voltage to pin 2 of JU5 or connect the on-
board MAX6126 2.5V reference by placing a shunt
across pins 1-2 of JU5. Measure and enter the value of
the external reference voltage into the Set Vref edit box
of the software GUI.
Part
Select the Part menu item at the top of the GUI and
check the device that is soldered in the U1 location on
the EV kit board. The software selects the MAX5535 as
the default device because the EV kit is shipped with a
MAX5535ETC+. Contact the factory for free samples of
the pin-compatible MAX553_ETC+, MAX552_ETC+, or
MAX551_ETC+ devices.
Gain
The default gain is set to 1V/V. To change the gain, first
remove R8 and R10. Next, install R8–R11 when using
surface-mount resistors, or R12–R15 when using
through-hole resistors. Refer to the MAX5535 IC data
sheet for information on selecting the resistor values.
Enter the new value of the gain into the Set Gain field of
the software GUI.
Debug
Select the Debug menu item at the top of the GUI to
execute low-level SPI interface commands. Enter data
into the Data bytes to be written edit box and press
the Send Now button for manual SPI operations.

User-Supplied SPI Interface
To use the MAX5535 EV kit with a user-supplied SPI
interface, first move the shunts of JU1–JU4 to the 2-3
position. Next apply your own 1.8V to 5.5V power sup-
ply at the VDD pad. Lastly, connect your CS, SCLK,
and DIN signals to the corresponding CS, SCLK, and
DIN pads on the MAX5535 EV kit board.
User-Supplied Power Supply
The MAX5535 EV kit is powered completely from the
USB port as default. Move the shunt of JU1 to the 2-3
position to apply your own 1.8V to 5.5V power supply at
the VDD pad.
