Class D audio amplifiers have been increasingly famous in the recent years. This article will present the what’s, why’s and how’s of Class-D audio amplifiers. The article will also present audio ...

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, ...

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 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 ...

Fig 1. This shows the spectra of both waveforms when the Class D output is issuing silence (no audio, duty cycle = 50%) with a switching frequency of 333 kHz. Fig 2. The blue line shows the energy ...

StormAudio has introduced a multichannel amplifier reinforcing the shift toward networked, software-driven AV system design ...

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 ...

Technology has democratized the music industry in many obvious ways – notice how every band, regardless of stature, has a MySpace page? But one of technology's more subtle effects has been to make our ...

I've been hosting an outdoor movie event for over 10 years now and have been slowly adding and upgrading equipment. There are usually around 30 people, pretty spread out and up to 50ft away from the ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...

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 ...
