Intelligent Class D Amplifier Controller Integrated Circuit as an Ingredient Technology for Multi-Channel Amplifier Modules of Greater than 50Watts/Channel

Digital input class D audio amplifiers will replace traditional analog types over the next 5 years. This paper describes a digital input class D amplifier controller integrated circuit (IC) which performs many of the functions needed to build a high performance class D audio amplifier module. A powerful Digital Signal Processor (DSP) is included allowing sophisticated modulation schemes, as well as additional audio signal processing. Possible processing functions include loudspeaker load compensation, equalization (EQ), time alignment, room acoustics compensation, howl prevention and other audio signal processing tasks. A novel clocking scheme decouples the input clock from the output switching clock, creating a highly jitter-tolerant design.
