Thank you for your interest in the latest generation of AudioMAX products. The LXE1710/1711 evaluation board is
a fully functional mono amplifier designed to demonstrate the “new and improved” Switching Class-D Power
Amplifier IC from Linfinity Microsemi. The LX1710/1711 is a completely new controller design with superior
performance over the LX1720 stereo controller IC. Key improvements include better SNR, lower noise floor, and
reduced THD therefore resulting in a much “quieter” and “cleaner” sounding amplifier.
The evaluation board has been configured with easy-to-use terminal block connections for power supply/battery hook
up and speaker connections. An RCA jack or separate audio +/- pins allow a quick interface to your audio source.
Jumpers are also provided to enable/disable the amplifier (Sleep control) and to turn off the audio input (Mute
control). With minimal setup, the user can be listening to the amplifier in a matter of a few minutes.
Both the LX1710 and LX1711 operate from a single supply voltage. The LXE1710 evaluation board can
accommodate a supply voltage from 7V to 15V which produces 25W into 4
and greater than 40W into 2
. The
LX1711 can handle a higher supply voltage (7V to 25V) and provides greater than 50W continuous output power
into 4
. The evaluation amplifier board has been designed for a 4
load. The output filter can be easily modified to
change frequency response for other load optimization.
