Stereo 2.8W Class D Audio Amplifier - TS2012

[botcabin1]

Hi,

I have purchased many of your different amplifiers including:

Stereo 2.8W Class D Audio Amplifier - TS2012

Stereo 3.7W Class D Audio Amplifier - MAX98306

Mono 2.5W Class D Audio Amplifier - PAM8302

Stereo 20W Class D Audio Amplifier - MAX9744

I would like to know how I can independently measure the Power that these boards supply to a speaker (ie, a 4-Ohm speaker).

Is there some type of Power meter that can be used? Also can I measure parameters with a standard VOM that will provide the Power value?

In advance, thank you!

There are meters that will measure power, but they tend to be expensive.

In most cases, you just use two meters: one connected to measure the current flowing into the circuit, and one measuring the voltage across the circuit. The product of current and voltage is power.
