Converting to Class D designs promises higher output power within the same system volume or miniaturization at existing power levels—both desirable for automotive audio and infotainment applications.

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

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 ...

Switching Amplifier (Class D) Basics - page 2 Amplifier Topologies and Low-Frequency EMI Performance So, although it seems that the effects of the attenuated switching fundamental aren't very severe, ...

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, ...

What does Class D amplifier actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

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.

Class D amplifiers run cool to the touch, but they haven't always sounded great. Now they're gaining favor with audiophiles.

Class D amplifiers maynot have much name recognition, but they're already changing the ways welisten to music, with the welcome side effect of shrinking and greeningthe world's audio hardware.

Class D is a digital-like amplifier that works by turning a transistor fully on or off, but the "D" technically does not stand for digital. See Class D amplifier.
