| description: | |
| The TAS2562 is a mono, digital input Class-D audio amplifier optimized for |
| efficiently driving high peak power into small loudspeakers. |
| Integrated speaker voltage and current sense provides for |
| real time monitoring of loudspeaker behavior. |
| |
| Specifications about the audio amplifier can be found at: |
