description: |
The NTP8835 is a single chip full digital audio amplifier
including power stages for stereo amplifier systems.
NTP8835 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. NTP8835C has identical programming interface,
but has different output signal characteristics.
