Digital power amplifier D series

Digital amplifiers, also known as Class D amplifiers (also known as Class D amplifiers in China), have the basic circuit of existing Class D amplifiers. The main function of digital amplifiers is that music signals cannot be directly amplified and must be converted into switch signals first. The amplifier operates in a switching state, and the power transistor is a field-effect transistor. The output end of the power amplifier has a low-pass filter composed of a coil and a capacitor.
