Circuit  of power audio amplifier with tda2003 for 10 Watts potency

TDA 2003 has a better performance than the tda2002 using the same configuration of pins. Additional characteristics in relation to the tda 2002, it demands few components external, easy assembly, it is a low cost solution for an audio amplifier. A mounted amplifier with tda2003 presents protection against short of the pins with the ground. The good of setting up an amplifier with tda2003 is that he easy of being found at the market, even for who is far away from the great centers, has the possibility to do to buy him/it integrated by the internet. The tda2003 can be supplied by batteries by a long period.

Description of the circuit of the amplifier of 10 watts simple source

It is treated of an assembly easy of being accomplished what is necessary it is just a tda2003 and one more half dozen of components.

To facilitate the assembly the circuit it counts with a circuit plate printed.

  1. As i understand from schematic:
    on the left side:1 In; 2 and 3 Ground
    on the right side: RL +Speaker ;+ V in; Ground

    Anyone assembled this one and thested with this values?

    Regards

  2. i’m a little bit confused in this project, i don’t know wheres the “+” and “-” for the input voltage and for the input of sounds and the output of the speaker.. please help me.. what is the input voltage?

  3. I have enjoyed myself browsing through this great circuit but if u can include the operation of the circuit
