ADAU1462WBCPZ300RL

ADAU1462WBCPZ300RL is an automotive qualified audio processor that far exceed the digital signal processing capabilities of earlier SigmaDSP® devices. This device is 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), multirate 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.
