ADAU1401AWBSTZ-RL

ADAU1401A is a complete, single-chip audio system with 28-/56bit audio DSP, ADCs, DACs, and microcontroller-like control interfaces. Signal processing includes equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, speaker compensation, and stereo image widening. This processing can be used to compensate for real-world limitations of speakers, amplifiers, and listening environments, providing dramatic improvements in perceived audio quality. The signal processing of the device is comparable to that found in high end studio equipment. Most processing is done in full 56bit, double-precision mode, resulting in very good low level signal performance. It is used in applications such as multimedia speaker systems, MP3 player speaker docks, automotive head units, minicomponent stereos, digital televisions, studio monitors, speaker crossovers, musical instrument effects processors, in-seat sound systems (aircraft/motor coaches).
