ANALOG DEVICES ADAU1451WBCPZ-RL Audio Control, SigmaDSP Digital Audio Processor, 2.97V to 3.63V, 1.14V to 1.26V, I2C, SPI

ADAU1451 is a sigmaDSP digital audio processor. The restructured hardware architecture is optimized for efficient audio processing. The audio processing algorithms are realized in sample-by-sample and block-by-block paradigms that can both be executed simultaneously in a signal processing flow created using the graphical programming tool, SigmaStudio�. The restructured 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 is widely used in application such as automotive audio processing, head units, navigation systems, rear seat entertainment systems, DSP amplifiers (sound system amplifiers), commercial and professional audio processing, consumer audio processing etc.
