Power Amplifier Circuit using TDA2009

Power Amplifier Circuit – 25 Watts

Description

Here is the diagram of a 25 Watt power amplifier circuit made of TDA 2009 IC.TDA 2009 has two channels each rating 12.5 watts on 4 Ohm load.Here the two channels are bridged to get a single out put channel weighting 25 W.

TDA 2009 IC has also built in features such as short circuit protection,thermal protection, overload protection etc using very low external components.The most interesting factor I see about this IC is that it require no dual supply.
