Have you ever read an amplifier review and encountered the terms Class A, Class A/B or Class D? We explain all.

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 ...

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

Apogee Technology has complained about some of Texas Instruments Inc.'s Class D claims. In March, TI called itself the first to introduce a single-chip Class D amplifier in the 125-watt/channel range.

Class D amps from $130 to $50,000—pulling more ears into hi-fi without demanding you sell a kidney. Solid tech, serious power, and none of the usual overpriced fluff. Finally, affordable doesn’t sound ...

Class D is particularly attractive in portable applications because it helps extend battery life. Complete 3-W class D amplifiers are now available in packages as small as 1.5 by 1.5 mm.

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

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.

Class D audio amplifier with 4th order output filter and self-oscillating full-state hysteresis based feedback driving capacitive transducers, Dennis Nielsen, Arnold Knott & Michael A. E. Andersen, ...

Savant 16-channel Class D Amplifier Savant Systems LLC, having delivered the first Apple-based home automation and control system, has announced the introduction of a 16-channel class D amplifier for ...

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, ...
