Class D audio amplifiers have been increasingly famous in the recent years. This article will present the what’s, why’s and how’s of Class-D audio amplifiers. The article will also present audio ...

Most audiophiles and enthusiasts have grown up with at least a basic understanding of what an amplifier does. It takes a tiny alternating electrical signal that represents the moment-to-moment ...

One of my first jobs as an engineer was at Empire Scientific Corp. in Garden City, NY in 1972. This was a high-end audio company that made speakers, turntables and phonograph cartridges. We had some ...

[Ben Laskowski’s] been working on a Class-D audio amplifier for several months. What you see above is the most recent version of the amp. A class-D amplifier uses transistor switching (or in this case ...

This file type includes high resolution graphics and schematics when applicable. Class D audio amplifiers are able to fulfill the requirements for audio applications such as mobile handsets, Bluetooth ...

If you’ve ever glanced at the specifications sheet for an amplifier, one of the things you may have noticed is the amplifier’s class. Typically denoted by a letter or two, the most common amplifier ...

Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers. Reaching efficiencies greater than 90% compared to only 50% for analog, ...

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.
