TDA2030 Datasheet

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

Also, you look at its circuit symbol pin connection below.

The TDA2030 integrated circuit is the best choice to make a 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).

For Example, the super Bridge 120 Watts—I love it. Because of small, easy using, and cheap.

For Example TDA2030 Circuits

Are you interest in it? Let’s see we can apply it to what circuits.

1# Small Versatile Power Amplifier, 12W OTL

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 the Volume popularity level of a sound signal.

If you cannot find a 22K potentiometer. You can use 50K instead.

See next circuit are better.

Recommended: Do you want higher output power than this?
Use TDA2050

2# Mini 15W OTL Power Amplifier with PCB

This is the main power amplifier of 15W OTL at 8Ω loudspeakers.

You should use a power supply of at least 24V 1A for MONO.

The Setting circuit on a class AB power amplifier to the output of the high harmonic distortion and low crossover.

They are ready, shock output protection, and the temperature is too high, complemented within the integrated circuit.

TDA2030 Stereo Amplifier OCL circuit diagram

As we listen to the sound quality nice. We turn the volume fully to several hours. The IC is not hot. Or just warm. so, suitable for beginners to build this circuit to listen with yourself.

Technical Specifications of IC-TDA2030

  • Begin working at a minimal voltage of +/- 6VDC.
  • Power driver output 14 watts at 4 ohms and 9 watts at 8 ohms.
  • The maximum current of 900mA.
  • Frequency response range 10HZ-140KHz at -3dB.

How this circuit works

In the circuit, the figure is a single channel amplifier. You will see that have very few parts. Both pin 1 and pin 2 of IC-TDA2030 input.

The pin 1 is non-inverting input and pin 2 is inverting input. Then input of power amplifier comes to C1 into pin 1 of IC.

  • The R3 determines the input impedance of the IC.
  • Pin 3 is -VCC leg or negative voltage, and pin 5 is a +Vcc or positive voltage.
  • Four capacitors C3, C4, C5, and C6 are bypass filter voltage +Vcc and -Vcc.
  • R1 as acts adjust the gain of IC with a negative feedback form. If R1 has higher resistance. Then, the gain rate of IC rises up as well.
  • The R4 and C7 are protectors a oscillated high frequency.

You need to put all parts correctly on PCB. Even You need to be careful putting the polarity of the electrolytic capacitors and Diodes right ways.

Recommended:

Full wave rectifier diodes

In the component layout, use both full wave rectifier diode that has three lead. For positive has A K A
And negative has K A K lead.  It may be an old part.   So you can apply two diodes connection as below circuit diagram.

full wave rectifier diodes

How to install TDA2030

The IC is the final sequence. You should install with a heat sink first. Then, Solder it on PCB. Because of if soldering IC first. The Holes between the ICs and the heat sink may be mismatched.

When all things are complete. Then, connect the speakers to the output. And connect the ACV of transformer current at least of 2A, ACV 12V CT 12V or 15V CT 15V, One or the other to the power connector terminal.

Testing

Our amplifiers are ready to test. We use a finger, touch input on both. It will noise of the hum out of the speakers. That sound is good. Then, use a good quality tone controls. To test the complete sound again.

    What are “aka” and “kak” coded parts near 1000uf capacitor? Are they rectifier diodes?

    Yours Sincerely…

    Reply
    • Hello sir, am Jackson, the coded aka and kak means you have to connect diode in the following arrangement
      AKA- Anode-Cathode-Anode, and KAK- Cathode-Anode-Cathode.

  6. 3# 14W TDA2030 Stereo amplifier circuit

    C8 should be at least 1000µF. C8=C9. C3 and C6(100µF) are useless as long as C8 and C9 are ten times greater(they are in parallel).

  7. Pin 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…

  8. 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

  9. 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

  10. 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.

  11. 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?

  13. Hey…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..

  14. 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.
