TDA2030 Datasheet Audio Amplifier Circuits Pinout

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.

TDA2030 Datasheet Audio Amplifier Circuits Pinout

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 the typical Application circuit diagram.

Typical application using TDA2030

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.

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

Versatile Power Amplifier

Versatile Power Amplifier TDA2030

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.

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.

i 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.

Friends the given circuit diagram is wrong


What is. Correct way?


Anyone know the proper connections.???.


The 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


pls give me a 5.2 channel circuit
simple ic transistor based
with power supply


Whis 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


Can we use the tda2050 place of tda2030, what watts of that type amp


how many inch speaker it take load


There 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.




yeh… 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.


Is 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?


Hi 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

Hey…i want to knw exacly can this curcuit use 2OHM speaker load?coz on explanation above blabla watt reach 200w on 2ohm 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… Read more »


I 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.
