13description:
14 The TAS2781 is a mono, digital input Class-D audio amplifier
15 optimized for efficiently driving high peak power into small
16 loudspeakers. An integrated on-chip DSP supports Texas Instruments
17 Smart Amp speaker protection algorithm. The integrated speaker
18 voltage and current sense provides for real time
19 monitoring of loudspeaker behavior.
