tda2003 Circuit of power audio amplifier with ic tda2003 for 10 Watt

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.

    i just want to know what is the input voltage of this amplifier?

  2. VOxOm says:

    Thanks you so much it’s really worked

  3. umer says:

    i want to know the name of the software on which this is simulated (tda2003)?

  4. fauzi rahmat says:

    where’s place potentiometers 10k

  5. erik says:

    can i use 40ohms resistor for Rx, and a 40nF for the Cx?

  6. dion cabansag says:

    thank you so much, i enjoyed browsing, my student admired and enjoyed searching for their projects through this site.

    of this cicuit?

  8. Wilfredo Perdomo says:

    Well, this one have an updated schematics, more detailed and with power supply for TDA 2002 and TDA2003 http://xtronic.org/circuit/amplifier/power-audio-amplifier-tda2002/ a udpdate note on top would a good idea. Regards

  9. Wilfredo Perdomo says:

    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

  10. mardel says:

    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?
