Analog Devices ADAU1452/ADAU1451/ADAU1450 SigmaDSP Digital Audio Processors are automotive-qualified and far exceed the digital signal processing capabilities of earlier SigmaDSP® devices. Their restructured hardware architecture is optimized for efficient audio processing. The audio processing algorithms are realized in sample-by-sample and block-by-block paradigms, which can both be executed simultaneously in a signal processing flow created using the graphical programming tool, SigmaStudio™. The new 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. The power efficient DSP core executes full programs while consuming only a few hundred milliwatts (mW) of power and can run at a maximum program load while consuming less than a watt, even in worst case temperatures exceeding 100°C. This relatively low power consumption and small footprint make the ADAU1452/ADAU1451/ADAU1450 ideal replacements for large, general-purpose DSPs that consume more power at the same processing load.
