Class d amplifier circuit

Class d amplifier circuit:

This is the Class D amplifier circuit diagram. This circuit can produce 100 watts. We can use 35-0-35 voltage and 5 amperes. It needs dual voltage. It’s a mono-circuit diagram board. Class D amplifiers are popular nowadays. Here, we use 2 MOSFETs only. 

The type of Designator is IRF9540N. type of Transistor is MOSFET. The type of Control Channel is P -Channel. The maximum Power Dissipation is 140 Watts. The maximum Drain-Source Voltage is 100 Volts. the maximum Gate-Source Voltage is 20 volts. The maximum Gate-Threshold Voltage is 4 Volts. The maximum Drain Current is 23 Ampers.

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