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/TAS5822/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.
