DATASHEET D2-4P Family Audio SOC FN6785 Rev 2.00 Mar 19, 2019 Intelligent Digital Amplifier PWM Controller and Audio Processor The D2-4P (D2-45057 and D2-45157) devices are complete System-on-Chip (SoC) Clas s-D digital audio amplifiers . These devices combine high performance integrated Power Stages, an optimized Audio Processor feature set, and a PWM controller to offer a complete, powerful, and very cost effective audio solution for high volume and cost-critical products. This 4th generation Digital Audio Processor (D2-4P) device combines extensive integrated Digital Signal Proces sor (DSP) audio processing with amplifier control for a complete audio solution. Its ease of integration into the existing system processor provides complete suppor t for all system product and amplifier functions. The four configurable Power Stages operate as four separate Half-Bridge outputs, as two Full-Bridge outputs, or in combinations of Half-Bridge plus Full-Bridge, which provides flexible loudspeaker drive solutions. Separate PWM outputs provide additional combinations to drive headphone outputs or line level stereo and subwoofer outputs.
