What Is a Class D Amplifier and How Does It Work?
A Class D amplifier is defined as a type of electronic amplifier that uses pulse-width modulation (PWM) to convert an analog input signal into a digital output signal, which is then amplified and converted back to analog to drive speakers. This type of amplifier is characterized by its high efficiency, often exceeding 90%, which means that it converts a large portion of electrical energy into audio power rather than heat.
According to the National Instruments website, Class D amplifiers operate by rapidly switching the output devices (transistors) on and off, creating a series of pulses that vary in width based on the amplitude of the input signal. This process allows the amplifier to efficiently modulate the power delivered to the load while minimizing energy loss. The output stage typically consists of complementary push-pull stages that enhance efficiency and reduce distortion.
Key aspects of Class D amplifiers include their operational efficiency, compact size, and ability to deliver high power output without generating substantial heat.
