DESCRIPTION
This board has a class D amplifier onboard that can drive 2 channels of 4-8 ohm impedance speakers at 20W each.
Since it’s class D, no heat sinks are required and it’s extremely efficient – up to 93% efficiency.
The MAX9744 amplifier has both analog and digital volume control capability. Use a single 1KΩ pot to adjust volume analog-style. Send I2C commands to set 64-steps of volume amplification.

Features
Power from 4.5V-14V DC voltage
Up to 93% efficient (88-93% typical)
20mA quiescent current (or put into shutdown for 1uA quiescent)
Up to 29.5dB max gain
Use DC or AC coupled line-level input, up to 3Vpp
Filterless Spread-Spectrum Modulation Lowers
