PCB design can limit the performance or reduce the reliability of a class-D amplifier if some basic layout guidelines are not followed. The following describes some good PC board layout practices for ...

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 ...

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 ...

The goal of audio amplifiers is to reproduce input audio signals at sound-producing output elements, with desired volume and power levels–faithfully, efficiently and at low distortion. Class D amps ...

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, ...

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 ...

Technology has democratized the music industry in many obvious ways – notice how every band, regardless of stature, has a MySpace page? But one of technology's more subtle effects has been to make our ...

Analog Devices has introduced two Class-D audio amplifiers designed to meet the low-power, small size, and growing sound quality requirements of portable electronics. Analog Devices has introduced two ...

Does the Peachtree Audio GaN400 power amplifier redefine Class D? Let’s take a deeper look at this new amplifier that offers over 400 watts per channel. Peachtree Audio are a very interesting company.

Analog Devices has created a pair of 22V stereo Class-D audio amplifier that idle at 6mA and shut-down to microamps. MAX98415A and MAX98425A are similar, and both including envelope tracking control ...

Class-D audio amplifiers represent a significant advancement in modern audio engineering by utilising high-frequency pulse modulation to drive output stages with exceptional efficiency. Unlike ...
