10 w amplifier using tda2003


Posted on Feb 6, 2014

This is a circuit diagram of amplifier circuit, these circuits have a 10W audio power amplifier using TDA2003 IC from SGS Thomson popular. The IC can easily provide 10W into 4 Ohms load at 18V DC supply voltage. IC can also be operated from 12V and that makes it applicable in a car audio system. Useful features include TDA2003 short circuit protec
