^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14)   The TAS2764 is a mono, digital input Class-D audio amplifier optimized for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)   efficiently driving high peak power into small loudspeakers.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16)   Integrated speaker voltage and current sense provides for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17)   real time monitoring of loudspeaker behavior.
