Introduction
The class d amplifiers are the most efficient amplifiers to use on the car audio amplifier and also the home audio systems. So in this post i would like to share the very simple 10 watt class d amplifier circuit using TDA7480 IC.
You know the major difference between Class a class b and class d amplifiers, class A has the highest sound fidelity but it produces the highest amount of heat. The class b amplifiers are more efficient amps than the class a audio amplifiers.
But the one disadvantage of the class b amplifier is about the distortion. The class d amplifiers are the most efficient amplifiers in the world, and it is most suitable for all types of applications.
TDA7480 10 watt Mono Class D Amplifier IC
The tda74980 is a 10 watt mono class d amplifier IC, that can be worked on the single supply and also the dual supply ( splitted voltages). The ic is most efficient and the heat sink is not required for its working. Several features available on this IC are the overvoltage protection and the stan-by mute features. The IC is designed dfo the TV and home audio system.The IC is coming in th empower DIP packaging.

Circuit Diagram
The DC maximum input voltage is about 20 V and I recommend using the 15 V DC supply. While using the circuit in the dual power supply mode you must use the 15 V dual power supply.
