If you need to build the amplifier circuit for your home. The TDA2030 Audio Amplifier Circuit may be best choice. Because it is cheap IC and easy to use. Suitable for beginners thought will build the electroacoustics to listen yourself. This project use IC of The SGS company number TDA2030, which SGS said that it is power amplifier IC in 5 pin form. Setting circuit on a class AB power amplifier to the output of the high harmonic distortion and low crossover, Ready, shock output protection, and the temperature is too high, complemented within the integrated circuit.
As we experiment to build this project, and listen to the sound quality nice. We turn the volume fully to several hours. The IC is not hot. Or just warm. Therefore, suitable for beginners build this circuit to listen with yourself.
Technical Specifications
– maximum voltage supply used of +/- 18VDC.
– Begin working at minimal voltage of +/- 6VDC.
– Power driver output 14 watt at 4 ohm and 9 watt at 8 ohm.
– Maximum current of 900mA.
– Frequency response range 10HZ-140KHz at -3dB.
The TDA2030 integrated circuit is best choice for make good audio amplifier circuit. It is used to make many amplifier output 10 watts to 200 watts. and a lot of types. Mono or Stereo and OTL, OCL, BCL (Bridge amplifier) Eg. the super Bridge 120W I love it because small, easy using, and cheap.
We can builds more circuits with it. below

16 Oct 2012Hi
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.

1 Nov 2012i have made the circuit bridge120W by i.cTDA2030 as per the circuit and pcb given but it does not work why? i do not know all connections and wiring has been checked could any help me in this matter

15 Jan 2013Pin 2 of two IC TDA2030 mustn’t connect Power.The Power will be connected with pin 5 of two IC TDA2030.Negative (pin 2) pole and positive pole(pin 1) connect with Audio signal…

2 Jul 2013Friends the given circuit diagram is wrong
Joel
7 Aug 2013What is. Correct way?
Joel
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

10 Aug 2013pls give me a 5.2 channel circuit
simple ic transistor based
with power supply
Joel
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

26 Jul 2016Me I have problems with the loadline protection for amplifier in circuit
Iwant2Know
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.
