Audio amplifier circuit 60 Watts:
This is an Audio amplifier circuit 60 Watts. this diagram can make 60 watts. it’s a mono diagram. here use TDA2052 this IC is a mono integrated circuit. here in this diagram we can use 6 voltage to 25 voltage. this diagram needs dual voltage. positive negative and ground voltage. normally we can use 18-0-18 voltage and 3 amperes. also we can use TDA7298 IC in this diagram.
The diagram is here
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.
Always we have to use a best quality of voltage. voltage is the important to make a good output watts. we know that voltage X amperes = watts. alwats we have to use a good quality of transformer to make ac voltage to dc voltage. and needs good quality of diode. and need best quality of capacitor to make pure dc voltage. and need a best quality of heat sink for the IC. because this type of IC makes hot.
