BD-225 Amplifier

A Class D amplifier is a type of audio amplifier that uses a digital switching technology to amplify audio signals. It is also known as a switching amplifier or a digital (erroneously) amplifier. Un- like traditional analog amplifiers, which use continuous voltage waveforms to amplify signals, Class D amplifiers employ a more efficient method that switches the input signal on and off rapidly.

HOW CLASS D WORKS

Class D amplifiers work by using ‘Pulse Width Modulation’ (PWM) to convert the audio signal into a series of highfrequency pulses. These pulses are then amplified by a Mosfet switching transistor, which acts as a switch that turns on and off at a high frequency. The width of the pulses determines the amplitude of the audio signal. The audio signal is first converted into a digital format by an analog-to-digital converter (ADC). The digital signal is then processed by a digital signal processor (DSP), which generates the PWM signal based on the input signal. The PWM signal is then fed into the switching transistor, which amplifies the signal and converts it back into an analog format through a low-pass filter.
