12description: |
13  The NTP8835 is a single chip full digital audio amplifier
14  including power stages for stereo amplifier systems.
15  NTP8835 is integrated with versatile digital audio signal
16  processing functions, high-performance, high-fidelity fully
17  digital PWM modulator and two high-power full-bridge MOSFET
18  power stages. NTP8835C has identical programming interface,
19  but has different output signal characteristics.
