A class-D puts out a pulse-width modulated (PWM) signal instead of the typical class-AB amplifiers linear signal The PWM signal contains the audio signal and the PWM switching frequency plus harmonics ...

Market demands for low-profile designs and high audio output make Class D audio amplifiers very attractive to makers of high-end domestic and automotive audio products. For audio designers, integrated ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...

This article was originally published in the Dec 14, 1998 issue of Electronic Design. Class-D audio power amplifiers (APAs) were first introduced nearly 50 years ago. Since then, they have been used ...

EPC has used GaN transistors to create a high-power Class-D two-channel audio power amplifier design. Instantiated in evaluation kit EPC9192, it is capable of pushing 700W/channel into 4Ω (or 2Ω) or ...

International Solid-State Circuits Conference in San Francisco always seems to make space for audio amplifier developments, and this year is no exception, with some extraordinary distortion and noise ...

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.

Addressing the core issues of latency and integration in developing audio amplifiers for today’s smart cockpits.

Review: The IQ Audio M300 MonoBlock amplifier is deceivingly good, delivering rated power with pristine fidelity and finesse in an efficient, cool running pint sized package. Class D at its best.
