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
|

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.
