+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.
