| The TAS2118/TAS2X20 is mono, digital input Class-D audio |
| amplifier optimized for efficiently driving high peak power into |
| small loudspeakers. |
| The TAS257x is 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. |
| The TAS2563/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. |
| The TAS5802/TAS5815/TAS5825/TAS5827/TAS5828 is a stereo, 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. |
