AUDIO AMPLIFIER USING TDA2003 IC

This is a simple audio-frequency (AF) amplifier using the amplifier IC TDA2003.  The main components are
  • TDA2003 IC
  • 10K Pot
  • 8 ohm loudspeaker 
  • Resistors 
  • Capacitors
  • Power Supply 6V
  • Breadboard or PCB
The circuit diagram shown below 
            The IC can easily deliver 10W to a 4 Ohms load at 18V DC supply voltage. The IC can be also operated from 12V and that makes it applicable in car audio systems. The useful features of TDA2003 include short circuit protection between all pins, thermal overload protection, low harmonic distortion, low cross over distortion etc.
