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.

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 ...

I hadn't heard of Fosi or class-D amplifiers until a few weeks ago. I had an old AudioSource amp in our whole-house wired setup die and they came up when searching for a replacement.

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, ...

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

TPA3122D2 IC is used as a class D audio amplifier and can deliver up to 15W of power at 10% distortions. The real advantage of using a class D amp, ...

Class D amplifiers are superior to their predecessors in many ways, but none of them matter to music fans unless they sound good, too.

Class-D audio amplifiers represent a significant advancement in modern audio engineering by utilising high-frequency pulse modulation to drive output stages with exceptional efficiency. Unlike ...

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 ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...
