100 watt amplifier board
This is a 100 watt amplifier board. it’s a mono-circuit diagram. TDA7294 is a popular IC. It can make 100 watts maximum in bridge mode. we can use single voltage Ac 15 volt to 28 volt. the output will depend on voltage. strong voltage can make a strong watt. we have to use a good-quality heatsink for the IC. because this circuit makes it so hot in bridge mode.
The circuit diagram. for stereo mode, we have to use dual circuit diagram.
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.
