ADAU1467WBCPZ300

ADAU1467 is a SigmaDSP digital audio processor that far exceed the digital signal processing capabilities of earlier SigmaDSP® devices. The audio processing algorithms support a seamless combination of stream processing (sample by sample), multirate processing, and block processing paradigms. The enhanced digital signal processor (DSP) core architecture enables some types of audio processing algorithms to be executed using significantly fewer instructions than were required on previous SigmaDSP generations, leading to vastly improved code efficiency. It has four input serial ports and four output serial ports. Each device has an asynchronous clock domain capable of operating as either a bit clock and frame sync. Each of the serial ports supports multiple data lines. Typical applications are automotive audio processing, head units, distributed amplifiers, rear seat entertainment systems, trunk amplifiers, commercial and professional audio processing.
