AudioAmp click is a straightforward click. It functions as an audio amplifier that takes a stereo input and outputs a mono mixdown.
AudioAmp click is powered by a Texas Instruments LM48100Q-Q1 Boomer™ Mono, 1.3W Audio Power Amplifier chip. It takes a stereo signal from a 3.5mm stereo jack – you can try it with the line out from your PC.
The dual inputs are mixed/multiplexed into a mono output that you can connect to a passive speaker with wires through the onboard screw terminals.
The LM48100Q communicates with your target MCU through the mikroBUS™ I2C interface, giving you 32-step volume control over both input channels. So you can even mix a little bit.
As an extra feature, the chip also has fault protection (protecting the hardware against short circuits).
