Below are the applications of power amplifiers across different sectors:

1.Consumer Electronics: Audio power amplifiers are used in almost all consumer electronic devices ranging from microwave ovens, headphone drivers, televisions, mobile phones and Home theatre systems to theatrical and concert reinforcement systems.

2.Industrial: Switching type power amplifiers are used for controlling most of the industrial actuator systems like servos and DC motors.

3.Wireless Communication: High power amplifiers are important in transmission of cellular or FM broadcasting signals to users. Higher power levels made possible because of power amplifiers increases data transfer rates and usability. They are also used in satellite communication equipment.
