Class D Audio Amplifiers: What, Why, and How

Class D Audio Amplifiers: What, Why, and How

Class D amplif iers, f irst proposed in 1958, have become increasingly popular in recent years. What are Class D amplifiers? How do they compare with other kinds of amplifiers? Why is Class D of interest for audio? What is needed to make a “good” audio Class D amplifier? What are the features of... »

A Little Theory of Class-D Amplifiers

A Little Theory of Class-D Amplifiers

Why Class-D? It is a known fact that Class-A or Class-AB amplifiers are rather inefficient and thereforeproduces rather little power for the buck. When it comes to subwoofers, and electrical low frequency enhanced subwoofers in particular, the requirement for high power is quite evident, which makes such a system unnecessarily expensive if the power is... »

Class D Fundamentals of Operation

Class D Fundamentals of Operation

Class D Amplifiers: Fundamentals of Operation Introduction Most audio system design engineers are well aware of the power-efficiency advantages of Class D amplifiers over linear audio-amplifier classes such as Class A, B, and AB. In linear amplifiers such as Class AB, significant amounts of power are lost due to biasing elements and the linear operation of... »

Theory Class D Amplifier

Theory Class D Amplifier

A Class D amplifier or switching amplifier is an electronic amplifier where all power devices (usually MOSFETs) are operated as binary switches. They are either fully on or fully off. Ideally, zero time is spent transitioning between those two states. Theoretical power efficiency of class D amplifiers is 100%. That is to say, all of... »
