SigmaDSP Compact Digital Audio Processor with Extended Internal Memory
Model: ADAU1466
- Qualified for automotive applications
- High performance SigmaDSP core enables low latency and audio applications
- Active noise cancellation (ANC)
- Echo-canceller and noise reduction (ECNR)
- Surround sound algorithms
The ADAU1462/ADAU1466 are automotive qualified audio processors that far exceed the digital signal processing capabilities of earlier SigmaDSP® devices. They are pin and register compatible with each other, as well as 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. 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.
