+description:
+  The TAS2781 is a mono, digital input Class-D audio amplifier
+  optimized for efficiently driving high peak power into small
+  loudspeakers. Integrated an on-chip DSP supports Texas Instruments
+  Smart Amp speaker protection algorithm. The integrated speaker
+  voltage and current sense provides for real time
+  monitoring of loudspeaker behavior.
