+
+description:
+  The NTP8918 is a single chip full digital audio amplifier
+  including power stage for stereo amplifier system.
+  The NTP8918 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.
