PWM Controller and Audio Processor 48-Pin QFN T/R

The D2-41151 (D2-41x51-QR) device is complete System-on-Chip (SoC) Audio Processor and Class-D Amplifier Controllers, offering a powerful yet very cost effective audio solution for high volume consumer products, including Digital TV systems, PC Multimedia Speakers, and Portable Device Docking Stations. This 4th generation Digital Audio Engine (DAE-4) device combines extensive integrated DSP processing and configurable audio processing algorithms, for complete audio system control. The D2-41x51-QR devices are built upon the proven technology present in D2Audio"s D2-814xx, D2-914xx, and D2-926xx families of Class-D Controller ICs, while providing an optimized feature set for high volume and cost-critical products. The D2Audio D2-41x51-QR devices offer the optimum balance of functionality and lowest system material cost, especially in an SoC system architectures with I2S audio output. All audio processing and amplifier control is handled by the D2-41x51-QR, and its ease of integration to the existing system processor handles all system control functions.
