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 ...

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 ...

In audio applications there is a trend towards Class D audio amplifiers as replacements for traditional Class AB electronics. The main driving forces are improved efficiency and space savings.

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 ...

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 ...

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 ...

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.

The benefits of using Class D amplifiers. What to look for when choosing a Class D amp. Making the tradeoff between THD+N and quiescent current. Back in the day (1970s), audio amplifiers like the ...

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, ...

The Mola Mola Ossetra is a $25,100 Class D mono amplifier delivering 350W into 8 ohms with ultra-low distortion, challenging Devialet in the high-end arena. The new Mola Mola Ossetra isn’t just ...

Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...

Analog Devices has created a pair of 22V stereo Class-D audio amplifier that idle at 6mA and shut-down to microamps. MAX98415A and MAX98425A are similar, and both including envelope tracking control ...
