MAX5258 Evaluation Kit
General Description
The MAX5258 evaluation kit (EV kit) provides a proven
design to evaluate the MAX5258 low-power, 8-bit octal,
digital-to-analog converter (DAC). The EV kit also
includes Windows
®
2000/XP- and Windows Vista
®
-com-
patible software that provides a simple graphical user
interface (GUI) for exercising the features of the
MAX5258.
The MAX5258 EV kit PCB comes with a MAX5258EEE+
installed. This EV kit can also be used to evaluate the
MAX5259EEE+ low-power 8-bit octal DAC (2.7V to 3.6V).
Contact the factory for free samples of the
MAX5259EEE+.

lined
refers to items from the Windows operating system.
Procedure
The MAX5258 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,
5258Rxx.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) Verify that all jumpers (JU1–JU7) are in their default
positions, as shown in Table 1.
4) 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.
5) 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\MAX5258
(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
installation. Refer to the USB_Driver_Help.PDF doc-
ument included with the software for additional
information.

6) Start the MAX5258 EV kit software by opening its
icon in the
Start | Programs
menu. When the
Part
Selection
window appears, click on the
MAX5258
radio button and then press the
Next
button. The
EV kit software main window appears, as shown in
Figure 1.
7) To measure the OUTA voltage, connect the first
DVM between H2-1 (OUTA) and H2-2 (GND).
8) To measure the OUTB voltage, connect the second
DVM between H2-3 (OUTB) and H2-4 (GND).
9) Verify that the voltage on both DVMs is approxi-
mately 0V.
10) Enter
0x3F
into the
D7 - D0 (Shift Register Data
Bits)
edit box.
11) Press the
Load All DACs
button.
12) Verify that the voltage shown on both DVMs is
approximately 1V.

Detailed Description of Software
The main window of the evaluation software (shown in
Figure 1) displays the voltages and codes for all DAC
input and output registers. In addition, the main window
has two tabs. The
Load DACs
tab sheet controls all of
the DAC loading features of the MAX5258. The

tab sheet (shown in Figure 2) con-
trols all of the DAC modes of the MAX5258. The
Load

buttons must be pressed to write the corre-
sponding mode settings to the DAC(s).
Software Reset
Press the
Reset All Registers
button to reset the
MAX5258’s registers and GUI to the power-on-reset
(POR) state. This can be done at any time and is highly
recommended after using the
Advanced User
Interface
window (Figure 3).

Advanced User Interface
A manual serial interface can be established by advanced
users by selecting
Options | Interface (Advanced Users)
from the menu bar.
For SPI, click on the
3-wire interface
tab (shown in
Figure 3). Enter data into the
Data bytes to be written:
edit box and press the
Send Now
button.
Detailed Description of Hardware
The MAX5258 EV kit provides a proven layout for the
MAX5258. An on-board analog output signal header
(H2), an on-board digital input/output signal header
(H3), and jumpers to disconnect the on-board micro-
controller are all included on the EV kit.
