+ The TAS2118/TAS2X20/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 TAS5825/TAS5827 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. The
+ integrated speaker voltage and current sense provides for real time
+ monitoring of loudspeaker behavior.
