ANALOG DEVICES ADAU1467WBCPZ300RL Audio Control, SigmaDSP Digital Audio Processor, 1.14V to 1.26V, I2C, SPI, LFCSP-EP, 88 Pins

ADAU1467WBCPZ300RL is a SigmaDSP digital audio processor. This automotive-qualified audio processor that far exceeds the digital signal processing capabilities of earlier SigmaDSP® devices. They are pin and register compatible with the ADAU1450/ADAU1451/ADAU1452 SigmaDSP processors. The restructured hardware architecture is optimized for efficient audio processing. The audio processing algorithms support a seamless combination of stream processing (sample by sample), multi-rate processing, and block processing paradigms. The SigmaStudio® graphical programming tool enables the creation of signal-processing flows that are interactive, intuitive, and powerful. Applications include automotive audio processing, head units, distributed amplifiers, rear seat entertainment systems, trunk amplifiers, commercial and professional audio processing.
