Power Driver Integrated Full Digital Audio Amplifier
NTP-8230
General Description
The NTP-8230 is a single chip full digital audio
amplifier including power stage for stereo amplifier
system. NTP-8230 is integrated with versatile
digital audio signal processing functions, high-
performance, high-fidelity fully digital PWM
modulator, a stereo headphone amplifier and two
high-power full-bridge MOSFET power stages.
The NTP-8230 receives digital serial audio data
with sampling frequency from 8kHz through
192kHz. It delivers 2 x 30 watts in stereo mode
without heat sink.
The NTP-8230 has a mixer and Bi-Quad filters
which can be used to implement the essential
audio signal processing functions like loudness
control, compensation of a loud speaker response
and parametric equalization.
All the functions of the NTP-8230 can be
controlled by internal register values via I2C host
interface bus.
