14 The TAS2562 is a mono, digital input Class-D audio amplifier optimized for
15 efficiently driving high peak power into small loudspeakers.
16 Integrated speaker voltage and current sense provides for
17 real time monitoring of loudspeaker behavior.
19 Specifications about the audio amplifier can be found at:
