RH-AUDIO

In 1958, the   Class D Amplifier   was first proposed. And in recent years, it has become more and more popular. The   Class D Amplifier   is designed to produce the input audio signal (with real, efficient and low distortion effect) on the sound output component at the desired volume and power level. Audio frequency range is about 20 Hz to 20 kHz, so there must be good frequency response in this frequency range as for the amplifier (when driving the speaker with a limited frequency band, the frequency range is reduced. For example woofer or tweeter). Output power capacity varies widely in accordance with the application: from headphones with several milliwatts (mW), the TV or personal computer (PC) audio with a few watts (W), "mini" home audio and car audio with dozens of watts, to household and commercial audio system with high power (hundreds of watts or more), and audio system in the theater or concert hall.

What is Type D Amplifier Class D Amplifier is the amplifier which drives the speaker by ON/OFF switch in the control switch unit. The class D amplifier was first proposed in 1958 and it has become more and more popular in recent years. In the past several generations, class D amplifier has been greatly developed, and the system designers have greatly improved the durability and audio quality of the system. In the traditional   type D amplifier , the analog or digital audio signal is converted into PWM signal by the controller before the signal is integrated into the power MOSFET tube in the power backend device. These amplifiers are highly efficient, and the very small radiator is used or no radiator is required at all. While it reduced the requirement for power output. The Advantages of class D amplifier In conventional transistor amplifiers, the output class amplifier contains transistors that provide the instantaneous continuous output current. There are many types o...
