Amplifier circuit diagram using TPA3100D2:
This is an amplifier circuit diagram using TPA3100D2. this diagram can make 40 watts. in stereo mode 20watts + 20watts. here we can use a minimum of 10 voltage to a maximum of 26 voltage.


This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and this circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker
