TDA2030 Amplifier Circuit With Basic Components

In this tutorial, I will show you a cheap class AB audio amplifier using a few components. If you need to build the amplifier circuit in your home. The TDA2030 Amplifier Circuit can be a nice choice. Because it’s miles a reasonably-priced IC and easy to use. The TDA2030 has excessive output contemporary and really low harmonic and crossover distortion. Also, This tool has a short-circuit and a too high-temperature safety system. As we experiment to build this task and listen to the sound great nice. We can listen to high volume for numerous hours.

Working of TDA2030 Audio Amplifier

The IC can either work on a dual-mode power supply or single-mode power supply, to keep this easy I actually have preferred 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 resistor R1 and R2 set up a potential divider across the 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 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 channel integrates them each to make it as a single channel.
