I have also given a very basic circuit below. The TDA2030A datasheet given at the bottom of this page consists of some basic circuits which can be used to make this IC work. The TDA2030 is breadboard friendly and hence can be easily tested using a breadboard. This IC can deliver up to 20W of output power, so you can run a 4Ω speaker at 12W or a 8Ω speaker at 8W. Audio amplifier circuits can also be made using simple op-amps, but if you need higher volume that is loud enough for a room then this power audio amplifier is will be the best choice. An audio amplifier is nothing but one that has the capability to amplify the audio signals from any audio source such as mobile phone jack or microphone so that volume is increased when the audio is played in a speaker. The TDA2030 is a powerful audio amplifier IC.
Note: Complete Technical Details can be found at the TDA2030A datasheet given at the end of this page. Short circuit and thermal protection is available.Wide range of power supply from 6V to 36V.Can provide up to 20 Watts as output power.Low frequency class AB amplifier most suited for audio amplification.Supply voltage, Minimum 6V and Maximum 36V The TDA2030 IC is a powerful audio amplifier IC able to deliver up to 20W of output power, so you can use it to run a 4Ω speaker at 12W or a 8Ω speaker at 8W.
