If you need to build the amplifier circuit for your home. The TDA2030 Audio Amplifier Circuit may be the best choice. Because it is a cheap IC and easy to use. Suitable for beginners thought will build the electroacoustic to listen to yourself. These projects use IC of SGS company TDA2030.
Which the SGS said that it is a great power amplifier IC on 5 pins form. And, setting a circuit on a class AB power amplifier. The TDA2030 has high output current and very low harmonic and crossover distortion.
Also, This device has the short-circuit and the too high-temperature protection system.
As we experiment to build this project and listen to the sound quality nice. We turn the high volume for several hours. The TDA2030 is not hot or just warm. So, suitable for beginners to build this circuit to listen with yourself.
Technical Specifications
- Maximum voltage supply used of +/- 18VDC
- Begin working at the minimum voltage of +/- 6VDC
- Power driver output 14W at 4Ω and 9W at 8Ω
- The maximum current of 900mA
- Frequency response range 10HZ-140KHz at -3dB

TDA2030 Pinout
I like this IC. Because it looks like transistor on TO-220, mini size. So, it is so easy to install on a heatsink. Look at a pin connection of top view. The tap connects to -Vs pin.
Also, you look at its circuit symbol pin connection below.
The TDA2030 integrated circuit is the best choice to make good audio amplifier circuit. It is used to make many amplifier outputs 10 watts to 200 watts. And a lot of types, Mono or Stereo, OTL, OCL, BCL (Bridge amplifier). Example, the super Bridge 120 Watts—I love it. Because of small, easy using, and cheap.
We can build more circuits with it below.
120W Subwoofer Power Amplifier
14W TDA20130 Stereo amplifier circuit
More clear new design
This is an OCL stereo amplifier using TDA2030. It is suitable for a small room as the output power of 14 watts + 14 watts at 4 ohms speaker. Also, you can build it easily with the PCB layout. And using a few components with 15 dual power supply for TDA2030. Continue Reading

30W TDA2030 transistor Amp with PCB
Versatile Power Amplifier
The multi-purpose Amplifier using TDA2030 circuit. It has power 8W(RMS) at 8Ω loudspeakers. It has low noise be valuable THD (Total harmonic distortion) 0.1%. When friends use Power supply Voltage Source 28V at 4Ω loudspeakers. It has the output power of 12W. But be high class the noise increases to are 2 times.
Besides still three be usable with Volt supply about 9V. but there is the electric power is down respectively. The VR1 use for Volume popularity level of a sound signal.
If you cannot find 22K potentiometer. You can use 50K instead. Look at others detail about TDA2030.
Mini main Power Amplifier with PCB
PCB of 15W OTL Power Amplifier using TDA2030
This is the main power amplifier of 15W OTL at 8Ω loudspeakers. You should use power supply at least of 24V 1A for MONO.
It is specified with PCB layout you can try to build this project.
TDA2030 Bridge Amplifier circuit, 35 watts
If you want a higher sound than only one. You can use this circuit. We called the TDA2030 Bridge amplifier. It is direct coupling to a speaker to be like OCL amplifier. But uses two ICs and more current in Still using the same voltage. Continue reading

my english is poor … sorry .
I read this article.
It is possible to make this amplifier circuit with MOSFET Transistors

30 Oct 2012i have made this circuit but it did not worked what the problem is there i do not know. however i shall try again to check it up. then will comment.

7 Aug 2013Anyone know the proper connections.???.
Joel
8 Aug 2013The problem is on the 2030 chip you have pin 3 and 5 reversed . Pin 1 is + and pin 5 should be on the same side in the schematic. Pin 2 is – and pin 3 should be on the same side in the schematic. Easy mistake

12 Aug 2013Whis it? In the parts list you show c2,3,4,5,7 as 0.022uf but in the schematic you show them as 0.22uf. There is a big difference. Also in the parts list you have c1 and c6 as 0.0015 uf 50v and 10 uf 16v but the schematic shows them as both 0.22 uf . Can u pleas write me with the correct info? What else is wrong with the project? Help please. I bought all the parts but can’t assemble until I know.
Thank u

9 Sep 2014There is little mistake in the circuit.if the output is 120watts then the power transistor getting DC+ voltage via TDA2030 ? It must be in parallel to 2.2ohms supply. it will not work in 6volt DC. It requires 12V/7Amps free from rippling DC.

25 Dec 2014yeh… i hav made dis circuit…
the sound quality is nice.
but the bass reflex is very poor..
i replace both TDA2030A IC to TDA2050..
and added one 1mF caps at the (+ve) input signal
and added one 2000mF caps at the output signal..
now the bass and the output power is increased to more… then before it has.

27 Nov 2017Is this circuit runs well? there is no rectifier in this circuit. so, will this circuit will run connecting 15 volt 2 amp transformer directly to the circuit board?

12 Feb 2015Hi everybody,
The circuit has many problems and it should be rectified before building this.
So if you are searching for tda2030a or tda2050 Integrated Circuits then you may visit the links below
Here is the complete Youtube video for building a stereo amplifier based on tda2030a great IC
and here is the complete PCB board and notes for building this great project

8 Aug 2016Hey…i want to knw exacly can this curcuit use 2OHM speaker load?coz on explanation above blabla watt reach 200w on 2ohm load..so that mean admin already test it on 2ohm without anyfailure overheating etc??The connection between PIN R4 and R8 2.2k resistor..the line conected like that way?i feel something not right on this schematic,,,U sure r4 & r8 connected that way??
pls dont confuse us on this all things right here..coz if something doesnt right happen our $$$ fly away…maybe cheap on u country but on my country???this chip reach $15.00 each for tda2030 /TDA2030A.power transistor O_O $ 14.00 each so 2 pair = 14×4,,the capasitor for ps also walla..50v/10000uF reach $46.00 each..

25 Aug 2016I rebuilt the circuit. One of the output tranisistors was blown up. There was also a bit of “Magic smoke”.
I hoped better caracteristics from this circuit.
