Offering true audiophile sound and low EMI, the AD1990/2/4/6 Class-D amplifiers feature less than 0.005% THD + N and up to 2 x 40-W output power. Integrating an internal sigma-delta modulator and a ...

Claiming to deliver audiophile-quality sound, the AD199x Class-D amplifiers also boast of outperforming PWM based Class-D schemes, through the combination of single-chip design featuring an internal ...

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 ...

A recent article in EE Times (The truth about Class D amplifiers) perpetuated several misperceptions in the digital amplifier/Class D market that should be clarified. The first misperception is the ...

The TAS5706 embarks as the industry’s first digital-input, 20W stereo Class-D amplifier with a closed-loop feedback architecture to produce a richer, more accurate sound quality. The device also ...

Essence just released the DPA-440 Class D Digital Audio Power Amplifier, which is being billed as the killer amp for audiophiles. This $1300 amplifier uses the latest Class D topology to provide a ...

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 ...

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.

Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers. Reaching efficiencies greater than 90% compared to only 50% for analog, ...
