Description
NTP3000 is a single chip full digital audio
amplifier including power stage for stereo or
2.1 channel amplifier system. NTP3000 is
integrated with versatile digital audio signal
processing functions, high-fidelity fully digital
PWM modulator and two high-power full bridge
MOSFET stages.
NTP3000 receives 2-channel serial audio data
with sampling frequency from 8 kHz to 192
kHz. It delivers 2x30W in stereo mode or
2x15W + 1x30W in 2.1 channel mode without
heat sink.
Combining use of built-in mixer and biquad
filters can make additional preprocessing like
bass management, loudness control, loud-
speaker response compensation and preset
parametric equalizers possible.
All the functions of NTP3000 are set by I2C
register configuration.
