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.

Where to use a TDA2030 amplifier?
The TDA2030 is a powerful audio amplifier IC. 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. 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. 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.
How to use TDA2030?
The TDA2030 is breadboard friendly and hence can be easily tested using a breadboard. The TDA2030A datasheet given at the bottom of this page consists of some basic circuits which can be used to make this IC work. I have also given a very basic circuit below.
The IC can wither work on dual power supply or single mode power supply, to keep this simple I have preferred single mode supply by using a 9V battery. The 5th pin (Vs) is connected to the positive terminal of the battery and the 3rd pin (Ground) is connected to the negative terminal of the battery. This IC is a power amplifier IC and hence requires a decent amount of current to operate, hence make sure your battery can source enough current.
The resistor R1 and R2 forms a potential divider across the pins 4 and 2. The two diodes D1 and D2 are used to protect the IC from reverse currents. The speaker LS1 can be any ordinary speaker of value 4Ω, 6Ω or 8Ω. The audio source C2(1) can be any audio source from a mobile jack or even a microphone. Just connect the positive point to C2(1) and ground the other point. Also note that this amplifier can amplify only mono channel sound signals. So if you have two audio wires for left and right channel combine them both to make it as a single channel.
Applications
- Used for Audio signal Amplification
- Suitable for high power amplification
- Capable of operating on dual/split power supply
- Can be used to cascade audio speakers
