NTP8910A
Power Driver Integrated Full Digital Audio Amplifier
General Description
The NTP8910A is a single chip full digital
audio amplifier including power stage for
stereo amplifier system. NTP8910A is
integrated with versatile digital audio signal
processing functions, high-performance, high-
fidelity fully digital PWM modulator and two
high-power full-bridge MOSFET power stages.
The NTP8910A receives digital serial audio
data with sampling frequencies of 32kHz,
44.1kHz, 48kHz, and 96kHz. It delivers 2 x 10
watts in stereo mode without heat sink.
The NTP8910A 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 NTP8910A can be
controlled by internal register values via I2C
host interface bus.
