Product Summary

The LX1722CDB 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 LX1722CDB 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 LX1722CDB is a complete Class-D audio solution.
