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.
