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 solution.
