NUVOTON NPCA110BA0YX

The NPCA110B device is a member of Sound Enhancing family optimized for low cost TV, portable devices such as docking stations for MP3-players and mobile phones, Multi-Media speakers, PC monitor speakers and Boom boxes. The NPCA110B integrates Waves MaxxAudio-3 Lite sound enhancement algorithms. These are proprietary, patented, psychoacoustic algorithms that compensate for the acoustic limitations of small CE devices. MaxxAudio-3 Lite algorithms enable reproduction of rich content, with a wide dynamic range and a full frequency range, on a limited audio system. For low-frequency reproduction, MaxxBass uses a patented psychoacoustic technique to create a perceived low bass, which can be extended up to 1.5 octaves lower than the original. This technique reproduces full and rich sounding bass tones. Power handling is done by MaxxVolume, which utilizes the power amplifiers and speakers to their full extent yet avoids clipping and distortion. The MaxxAudio-3 Lite software suite provides an additional algorithm to design a resonance-free audio system: MaxxEQ provides a flexible equalizer with 10 bands.
