Electronics Help Care Amplifier circuit diagram Amplifier circuit diagram using TDA2005:
This is an amplifier circuit diagram using TDA2005. It’s a complete audio circuit board. mono board. This board can make 25 watts in bridge mode. 12-volt-operated audio board. It’s also with a pre-amplifier and bass treble controller. Here are 3 adjustable volumes: 1st one for the main volume, 2nd for the Treble, and another for the Bass.
The Diagram is
This is the Speaker protection circuit diagram. It can protect our Speaker from burns. 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
Audio amplifier circuit using TDA2050:
This is an audio amplifier circuit using TDA2050. Here, use one IC and 2 transistors. tip41 and tip42 transistors. TDa2050 works as a driver. Here, 18-0-18 volts and 3 amperes. The dual voltage is needed to run this circuit. positive negative,e, and ground voltage.
This is the DIY 12-volt car amplifier circuit diagram using the TDA2004 IC. It’s a stereo audio circuit with a bridge mode IC. Here, the IC is used in bridge mode. We can use a DC 12 volts or a battery. Normally, this circuit is used in a car amplifier. This IC in stereo mode is 10+10 watts. and bridge mode 25 watts.
