20
Watt Bridged Audio Amplifier Circuit - Assembled
This is a compact, yet powerful
audio amplifier using two TDA2003 monolithic Integrated Circuits
connected in bridged configuration to achieve more output power at 12V
DC supply. It can deliver more than 20W of music power into a 4-Ohm
speaker and is ideal for any kind of audio amplification application.
