MAX13335E Evaluation Kit
Evaluates: MAX13335E/MAX13336E
Quick Start
Recommended Equipment
• MAX13335E EV kit (USB cable included)
• Function generator
• Oscilloscope
• User-supplied Windows XP, Windows Vista, or
Windows 7 PC with an available USB port
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 EV kit is fully assembled and tested. Follow the
steps below to verify board operation. Do not turn on
the power supply until all connections are completed.
1) Visit www.maxim-ic.com/evkitsoftware to down-
load the latest version of the EV kit software,
13335ERxx.ZIP. Save the EV kit software to a
temporary folder and uncompress the ZIP file.
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 on the desktop and in the Windows Start |
Programs| Maxim EVKIT Software menu.
3) Verify that all jumpers are in their default positions,
as shown in Table 1.
4) Set the function generator output to high impedance
and to output a 1kHz, 10V
P-P
, sine wave with 0V
offset. Disable the function generator.
5) Connect the function generator output to the
INPUTL+ and INPUTR+ PCB pads.
6) Connect the function generator ground to the GND
PCB pad.
7) Connect the INPUTL- and INPUTR- PCB pads to the
GND PCB pad.
8) Connect the oscilloscope channel 1 to the OUTL
PCB pad.
9) Connect the oscilloscope channel 2 to the OUTR
PCB pad.
10) Connect a USB cable between the PC and the Mini-
USB port on the EV kit. A New Hardware Found
window pops up when installing the USB driver
for the first time. If a window that is similar to the
one described above is not seen after 30s, remove
the USB cable from the board and reconnect it.
Administrator privileges are required to install the
USB device driver on Windows.
11) Follow the directions of the Found New Hardware
window to install the USB device driver. Refer to the
USB_Driver_Help_200.PDF document included with
the software for additional information.
12) Start the EV kit software by opening its icon on
the desktop or in the Start | Programs | Maxim
EVKITSoftware menu. The EV kit software main
window appears, as shown in Figure 1.
13) Wait while the software connects to the EV kit. Once
the connection is established, the bottom-left status
bar displays Hardware: Connected.
14) Enable the function generator.
15) Verify that the oscilloscope channels 1 and 2 each
output a 1kHz, 2V
P-P
, sine wave with 0V offset.
Detailed Description of Software
Graphical User Interface (GUI)
The MAX13335E EV kit software GUI provides a
convenient way to test the features of the MAX13335E IC.
Figure 1 shows the EV kit software’s main window. The
EV kit software main window divides the EV kit functions
into logical blocks. Actions on this software window
generate I
2
C commands to update the IC’s internal
memory registers.
