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.

Hang around in any of the many guitar or audiophile forums or discussion boards for long enough, and eventually you’ll come across the arguments over amplifier topologies. One of the more interesting ...

Most audiophiles and enthusiasts have grown up with at least a basic understanding of what an amplifier does. It takes a tiny alternating electrical signal that represents the moment-to-moment ...

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 ...

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.

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 ...

A Zobel is an impedance matching circuit often used with loudspeakers. A Zobel circuit is also known as a Boucherot cell or somewhat incorrectly as an RC snubber. The nominal impedance of a ...

The efficiency and size advantages of Class D audio amplification in battery- powered devices are well known. These advantages are now extended to amplifiers up to 500W, made possible by solidstate ...

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 ...
