INTRODUCING LX1710/1711 AUDIOMAX
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.
