Thank you for your interest in the latest generation of AudioMAX products. The enclosed LXE1710 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

Thank you again for your interest in the new “quieter”, high efficiency Class-D Audio Amplifier from Linfinity

Microsemi. Please let us know what you think and stay tuned for future product releases to our AudioMAX family

of products.
