| 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. |
