14 The TAS2770 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.
27 I2C address of the device can be between 0x41 to 0x48.
