Working Principle of TDA2030 Amplifier Circuit
The IC can either work on a dual-mode power supply or a single-mode power supply, to keep this easy I actually preferred a single-mode power supply by using a 12V supply. The 5th pin is connected to the Vcc terminal of the supply and the 3rd pin is hooked up to the negative terminal of the supply. This IC is a power amplifier IC and hence requires a decent amount of contemporary to operate, hence make sure your power supply can supply enough current.
The resistors R1 and R2 set up a potential divider across pin 4 and pin 2. The two diodes D1 and D2 are used to shield the IC from opposite currents. The speaker SP1 may be any regular speaker or tweeter of value 4Ω, 6Ω or 8Ω. The audio input supply C2 can be any audio source from a 3.5mm jack or maybe a microphone. Just connect the Vcc terminal to C2 and ground the other point through the R3 resistor. Also, remember that this simple amplifier can amplify the handiest mono-channel sound signals. So when you have two audio channel wires for the left and right channels integrate them each to make it a single channel.
