Description

The LX1721/1722 is a monolithic high performance Class-D stereo controller IC designed for high efficiency or space constrained audio requirements such as portable or battery operated products, automotive amplifiers, and multi-channel multimedia computer and video game applications. This high frequency, full audio bandwidth switching power amplifier controller offers dramatically improved performance over Linfinity's previous generation amplifier products. Enhancements include higher output power, better SNR, lower noise floor, and reduced THD. Combined with output power MOSFET's and an output filter, the LX1721/1722 is a complete Class-D audio

A complete audio amplifier module available to quickly evaluate the LX1721 or LX1722 stereo 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, satellite / subwoofer combinations and various speaker loads (2Ω 4Ω, 8Ω). The versatile amplifier solution can easily be adjusted for frequencyresponse, optimized for efficiency and performance, or designed to minimize PCB area and component count. The LX1721/1722 is available in a space saving 44-pin QSOP package. (Continued Next Page)
