Overview of Digital Amplifier

                                                     Overview of Digital Amplifier

A digital amplifier is an amplifier with characteristics such as low distortion, low noise, and large dynamic range. Its basic circuit is a Class D amplifier (Class D amplifier). A digital power amplifier mainly consists of three parts: signal modulation, power amplification, and output filtering. The input audio analog signal is modulated and processed through a PWM circuit, and then amplified and filtered through a switch circuit to restore the amplified audio signal. Digital amplifiers are widely used in fields such as car audio and home theaters, with high fidelity and clear sound quality, making them an important development direction for power amplifiers.
