Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1) Visit www.maxim-ic.com/tools/evkit/ to download
the latest version of the EV kit software, 9880ARxx.
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 in the Windows Start | Programs menu.
3) Verify that the shunts on jumpers JU13, JU19, JU20,
and JU27 are configured as shown in Figure 1 (the
line indicates a shunt installation).
4) Verify that the remaining jumpers are configured as
listed in Table 1.
5) Connect the USB cable from the PC to the EV kit
board’s J7 mini-USB connector. A Building Driver
Database window pops up in addition to a New
Hardware Found message if this is the first time the
EV kit board is connected to the PC. If a window is
not seen that is similar to the one described above
after 30s, remove the USB cable from the EV kit and
reconnect it. Administrator privileges are required
to install the USB device driver on Windows 2000,
Windows XP, and Windows Vista.
6) 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\MAX9880A (default installa-
tion directory) using the Browse button. Refer to the
USB_Driver_Help.PDF document included with the
software for additional information.
7) Connect the headphones to the capless 3.5mm
headphone jack (J4) and/or speakers to the OUTR
(J8) and OUTL (J9) RCA output connectors.
8) Connect the audio source to the mini-USB input con-
nector (J10).
9) Enable the audio source.
10) Start the EV kit software by opening its icon in the
Start | Programs menu.
11) Perform a software quick start by selecting the
Quick Start F3 menu item from the Tools menu bar
(or by pressing F3).
12) Verify that the input audio can be heard through the
connected headphones and/or speakers.
13) The EV kit is now ready for further evaluation.
