50 Watts amplifier using CXD9646Z
This is a 50 Watts amplifier using CXD9646Z. We can use 12 to 32 volts and get 50 watts. it’s a mono-circuit diagram. We have to use dual circuits to make the stereo. we can use this amplifier in car audio.
This IC made by Panasonic. 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.
