About The Circuit

Here is the circuit diagram of a 2X15 Watts stereo amplifier, which is also reffered to as a 30 Watt mono BTL amplifier. The IC called TDA 4935 is used here. This bipolar stereo amplifier has a built in circuitory for protection from overload as well as overtempreature shut down. The main features of this circuit is that there is no need of a dual power supply and it has a power voltage varying from (8-24)Volts.

The K1 and K2 speakers should have a rating of 20 Watts, 4 Ohms. The electrolytic capacitors should have a minimum rating of atleast 25 Volts.
