+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.
