LXE1710 EVALUATION BOARD
USER GUIDE
QUICK START GUIDE
The LXE1710 Evaluation Board is a fully functional,
Class-D Amplifier. Connection to a single supply
voltage (VDD from either a battery or power supply),
speakers, and your audio source is all that is required
to begin evaluating the amplifier and listening to music.
The following outlines the necessary connections and
control jumpers.
1) Verify contents of Evaluation Kit: The easy-to-
use amplifier is all contained on a single board.
Visually inspect to see if the board or any
components were damaged during shipping.
All components are located on the top side of
the PCB except for the decoupling capacitor,
C17. A copy of the LX1710/1711 Datasheet
should also be enclosed or a PDF version can
be downloaded from the Microsemi.com
website
(http://www.microsemi.com/datasheets/MSC1580.PDF).
2) Power and Ground Connections: The voltage
supply and ground connections are made
through terminal block TB1. Connect your “+”
(+7V to +15V) power supply or battery to the
+V input of TB1. Connect your supply or
battery ground to the GND input of TB1.
Please ensure the correct positive and ground
connections are made before turning on the
power supply.
3) Speaker Connection: The amplifier is designed
$ ! # "
“+” and “-“ to the +OUT and –OUT input of
terminal block TB2 respectively. The amplifier

can be used to drive other speaker loads but
frequency response may not be optimal. See
LC filter design section for recommended
inductor and capacitor modifications.
4) Audio Input Connection: Connect your audio
source to the RCA Jack CN1, Audio In. For
other type interfaces, the audio input signal can
also be connected to the amplifier board using
the J3 (In- and In+) location. Strip Line Plugs
can be inserted into J3 for connectivity.
5) Jumper Selection Controls: The “on/off” or
enable to the module is controlled with the
SLEEP/ signal. Jumper J1 connects the
SLEEP/ to “on” or “ off”. SLEEP/ is an active
Low control. Jumper J2 connects the MUTE
control which enables/disables the audio input
to the amplifier. MUTE is an active High signal.
See table below.
6) Power Source: If a power supply is being used,
make sure it is set to the correct voltage level
and turn the power supply on.
7) Audio Source: Make sure the audio source
signal is set to a minimum level. Start or “play”
audio source and adjust source volume to
desired level.
8) Listen to AudioMAX: If the amplifier is not
operating properly, verify preceding steps or
