14 The TAS2764/TAS2780 is a mono, digital input Class-D audio amplifier
15 optimized for efficiently driving high peak power into small
16 loudspeakers. Integrated speaker voltage and current sense provides
17 for real time monitoring of loudspeaker behavior.
28 I2C address of the device can be between 0x38 to 0x45.
