Tda2003 Subwoofer. By implementing this tda2003 ic in a low power audio amplifier we can built low harmonic and cross over distortion amplifier. Here is a simple circuit of 20 watt audio amplifier using tda2003 ic to amplify weak audio signal.
Various types of amplifier circuit have already posted in amplifier circuit section. It requires very low external components to operated as a amplifier and also it can provide high current output. It can also handle short circuits in both ac and dc rail without killing itself.
The useful features of tda2003 include short circuit protection between all pins thermal overload protection low harmonic distortion low cross over distortion etc.
The amplifier can output upto 3 5a current to drive speakers and can also handle high current upto 5a for shorter duration without any damage. Tda2003 is a general purpose audio amplifier circuit ic for stereo or mono audio design circuits. Tda2003 is a general purpose 10w amplifier ic that can be used in stereo or mono audio design circuits. It can also handle short circuits in both ac dc rails without damaging itself.
