Class D amplifiers run cool to the touch, but they haven't always sounded great. Now they're gaining favor with audiophiles.

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, ...

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.

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 ...

Although thus far we have shown class D amplifiers for power amplifier applications, there is another area of need in the signal chain for good sound reproduction—the loudspeaker.

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 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 ...

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

As for overheating, that's what the whole class-D/switching amplifiers are supposed to be good at. They're supposed to be so efficient that they barely give off heat.

The Cherry Audio MEGAschino Mk2 Standard Edition Class D Amplifier is energy efficient, boasting SOTA specs and gobs of power output (>400wpc, 8 ohms). Is it worth the $6k price? Read our review.

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

The Class D amplifier, which is having a massive, albeit largely unacknowledged effect on consumer audio devices, is responsible.
