  The TAS2118/TAS2X20 is mono, digital input Class-D audio
  amplifier optimized for efficiently driving high peak power into
  small loudspeakers.
  The TAS257x is mono, digital input Class-D audio amplifier optimized
  for efficiently driving high peak power into small loudspeakers.
  Integrated speaker voltage and current sense provides for real time
  monitoring of loudspeaker behavior.
  The TAS2563/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.
  The TAS5802/TAS5815/TAS5822/TAS5825/TAS5827/TAS5828 is a stereo,
  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.
