| 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. |
