The NTP-3100L is a single chip full digital audio amplifier including high operating voltage power stage for stereo amplifier system. NTP-3100L is integrated with versatile digital audio signal processing functions, high-performance, high-fidelity fully digitalPWM modulator and two high-power full bridge MOSFET power stages. The NTP-3100L receives digital serial audio data with sampling frequency from 8KHz to 192KHz. It delivers 2 x 30 watt in stereo mode without heat sink. The NTP-3100L has mixer and Bi-Quad filters which can be used to implement the essential audio signal processing functions like loudness control, loud speaker response compensation and parametric equalizers. Also it's possible to individual control with high frequency and low frequency through thedual band DRC. All the functions of the NTP-3100L can be controlled by internal register values via I2C host interface bus.
