Circuit of power audio amplifier with tda2003 for 10 Watts power. TDA 2003 has a better performance than the tda2002 using the same configuration of pins. Additional characteristics relate to the tda2002, 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 is 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 printed circuit board.
