GENERAL DESCRIPTION
●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, cross over, bass enhancement, multiband dynamics processing, delay compensation, speaker compensation, and stereo image widening and can be used to compensate for real-world limitations of speakers, amplifiers, and listening environments, providing a dramatic improvements of perceived audio quality.
●FEATURES
