AUDIO: NTP-3000
1 chip 2.1 channel full digital amplifier
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 mudulator 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 model without heat sink.
Combining use of built-in mixer and biquad filters can make additional
preprocessing like bass managemen, loudness control, loud-speaker
response compensation and preset parametric equalizers possible.
All the functions of NTP3000 are set by I2C register configuration.
