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.
