Audio Amplifier TDA200 3A

This audio amplifier circuit takes a quiet sound signal and makes it louder so it can be heard clearly through speakers or headphones. It does this by using electronic parts like transistors or chips to boost the sound without changing it too much. The circuit is made up of a few stages that each help increase the signal’s strength, and it uses extra parts like resistors and capacitors to keep the sound clean and stable. Basically, it helps small sounds become big enough to fill a room.
