Description
This 2 x 30W Class-D Amplifier board features the TPA3110 Hi-Fi Audio amplifier chip with high efficiency, low distortion and a high signal-noise ratio of about 100dB.
The recommended speaker impedance is 4-8 Ohms.
A DC power supply of 8-26V is required and it should be clear that only a high voltage will result in the maximum output power and that the power supply also needs to be able to deliver the required current of up to 3.5A. Please refer to the diagrams in the TPA3110 datasheet.
Inputs, Outputs and Power Supply Connections are clearly marked on the module and don’t require any further instructions. Again, if you have questions about certain details, have a look at the datasheet.
Module size is 53 x 45 mm

This amplifier can be driven directly from an Alexa Echo Dot; no volume control required. I used an old laptop power supply at 19V. The module was able to drive bookshelf sized speakers to a high volume. I can’t comment on the audio quality because the Echo Dot does not seem to output a wide audio spectrum.

I feed this amplifier with a signal derived from a DAB/FM radio, and it drives hi-fi speakers; the result sounds good to me. I did discover, however, that the labels on the right-hand output pads are swapped; the correct order of the pads along the edge of the board is R+, R-, L-, L+.
