Converting to Class D designs promises higher output power within the same system volume or miniaturization at existing power levels—both desirable for automotive audio and infotainment applications.

A new book authored by Robert N. Buono delves deeply into Class-D amplifiers, a crucial technology in audio designs. Buono ...

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 ...

Different Forms of Class D Amplification Though we may think that “digital” means all the circuits in a digital amplifier work in on/off pulses, in fact there are a number of different types, ...

A class-D amplifier uses transistor switching (or in this case MOSFET switching) to generate the pulse-width-modulated signal that drives the speaker.

Nuvoton has released the NAU83U25YG, an automotive-grade Class-D audio amplifier designed for vehicle electronics ...

A Class D audio amplifier is a switching amplifier that consists of a pulse width modulator (with switching frequency in the order of several hundred kHz), a power bridge circuit and a low pass filter ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...

Class D amplifiers are superior to their predecessors in many ways, but none of them matter to music fans unless they sound good, too.
