ADAU1702JSTZ 音频IC DSP

ADAU1702JSTZ

音频 SigmaDSP 28-/56-Bit Audio Processor  with Two ADCs and Four DACs

GENERAL DESCRIPTION  ADAU1702JSTZ

The ADAU1702 is a complete single-chip audio system with a  28-/56-bit 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.
