Amplifier circuit diagram 200 watts:

This is an amplifier circuit diagram for 200 watts. This board produces 200 watts using dual TDA7297. It’s a bridge mode diagram. We can use 15-0-15 voltage to 24-0-24 voltage. It’s a mono board. the voltage should be a strong voltage to get a good output watts.

TDA7297 is a stereo IC. Here used in bridge mode.

Amplifier circuit diagram TDA7294:

This is an Amplifier circuit diagram for TDA7294. Here, use 4 ICs. This circuit can make 350 watts. It’s a bridge mode board. we can use 20-0-20 voltage to 40-0-40 voltage and 5 amperes. Here, a good-quality heatsink is needed for the IC. Always use high-quality voltage to achieve the best sound and wattage.

Amplifier circuit diagram TDA7294

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.
