General Description  

The Nuvoton NPCA110P device is a member of Nuvoton’s  Sound Enhancing family optimized for portable devices such  as docking stations for MP3-players and mobile phones, MultiMedia speakers, PC monitor speakers and Boom boxes.  

The NPCA110P integrates Waves MaxxAudio 3 sound  enhancement algorithms. These are proprietary, patented,  psychoacoustic algorithms that compensate for the  acoustic limitations of small CE devices.  The MaxxAudio 3 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 distortions.  

The MaxxAudio 3 software suite provides additional algorithms that enhance the overall sound quality, such as  Maxx3D, which widens the stereo image, and MaxxTreble,  for reproducing crystal clear high frequencies. To design a  resonance-free audio system, MaxxEQ provides a flexible  equalizer with 10 bands.  The NPCA110P enables digital control over the Volume and  Bass, replacing traditional analog potentiometers. Additional digital controls for selecting a specific music style (Jazz,  Vocal, Rap, Classical, etc.) can also be added.  

The Maxx family of devices includes:  

■ High-performance, 24-bit audio enhancing engine preprogrammed with Waves MaxxAudio 3 algorithms  

■ Optional Audio ADC  

■ Optional Audio DAC  

■ Digital I/O and other features for high-performance  audio systems
