M I C R O S E M I C O M P A N Y Audio MAX™ P RELIMINARY LX1710/1711 Class-D Mono Power Amplifier Controller IC The LX1710/1711 is a monolithic high performance integrated class-D controller IC designed for high efficiency audio requirements such as portable or battery operated products, automotive amplifier, and multimedia applications. This high frequency, full audio bandwidth switching power amplifier controller, is a pletely new design with dramatically improved performance over Linfinity’s previous generation amplifier products. Enhancements include better SNR, lower noise floor, and reduced THD. bined with output power MOSFET’s and an output filter, the LX1710/1711 is a plete class-D audio solution. A plete audio amplifier module is available to quickly evaluate the LX1710 controller. Simply connect the amplifier to the power source, audio signal, and speakers. Reference designs support a variety of requirements including multi channel systems, subwoofers, and various speaker loads (2 amplifier solution can easily be adjusted for frequency response, optimized for efficiency and performance, or designed to minimize PCB area and ponent count. The LX1710/LX1711 is available in a space saving 28-pin SSOP package. Integrated Switching Class-D W W W . Microsemi .
