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.
|
||
|
|
|
||
|
