A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

Hang around in any of the many guitar or audiophile forums or discussion boards for long enough, and eventually you’ll come across the arguments over amplifier topologies. One of the more interesting ...

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

Add Yahoo as a preferred source to see more of our stories on Google. Ayre KX-R internals If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have ...

As Axiom’s chief R&D engineer Tom Cumberland describes it, a digital amplifier is a “power DAC”, and of course a DAC (Digital-to-Analog Converter) is the basis of all digitally recorded media, whether ...

Class D amps are simple – just take an input, and use that to modulate a square wave with PWM. Send this PWM signal to a MOSFET or something, and you have the simplest class D amp in existence.

In this chapter, the different configurations of Class-D power amplifiers are presented the increased efficiency of which is a result of employing the active device as switches. First, the ...

What is class D amplification? Class D amplifiers are a more efficient alternative to class AB (push-pull) power amplifiers for audio signals. Class D is particularly attractive in portable ...

A new generation of digital-input Class D audio amplifiers achieves high PSRR performance that is comparable to traditional analog Class D amplifiers. More importantly, digital-input Class D ...
