ADAU1701 Datasheet PDF - ADI

●GENERAL DESCRIPTION

●The ADAU1701 is a complete audio system-on-a-chip including a 28/56-bit audio DSP, ADCs and DACs, and microcontroller-like control interfaces. Signal processing includes equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, speaker

●compensation, and stereo image widening. These algorithms can be used to compensate for the real-world limitations of speakers, amplifiers, and listening environments, resulting in a dramatic improvement of perceived audio quality.
