The 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.
