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

To demo this, [Afrotech] used TI’s TPA3122 class d amplifier chip. It’s a pretty cheap chip for being a 15 Watt stereo amplifier, and the circuit is simple enough to build on a breadboard.

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

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 ...

The Class D amplifier topology theoretically offers ideal characteristics for audio: 100% efficiency, 0% THD, and no audible noise. While practical Class D implementations can come attractively close ...

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

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 ...

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 ...

Trade offs in designing with IC and discrete component class D amplifiers including switching speeds, filtering options, and power supply considerations.
