description:
  The TAS2781 is a mono, digital input Class-D audio amplifier
  optimized for efficiently driving high peak power into small
  loudspeakers. An integrated 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.
