Class D Audio Amplifiers: What, Why, and How - Analog …
https://www.analog.com/en/analog-dialogue/articles/class-d-audio-amplifiers.html
The goal of audio amplifiers is to reproduce input audio signals at sound-producing output elements, with desired volume and power levels—faithfully, efficiently, and at low distortion. Audio frequencies range from about 20 Hz to 20 kHz, so the amplifier must have good frequency response over this range (less when driving a band-limit…
Class D Amplifier Disadvantages: You Must Know the …

On the whole, Class D Amplifiers not only deliver high-quality sound but are also very energy efficient. The Bad. In the past, Class D Amplifiers produced a hard flat sound. The clarity of the sound is slightly less crisp than the larger amplifiers, but not enough for a “lay person” to discern a large difference.

Even so, the efficiency of a practical Class-D amplifier can be better than 90 percent, which is significantly better than a Class-AB design (78.5 percent at best and typically closer to 50 percent). Coming full circle, because a Class-D amplifier is more efficient than the conventional Class-AB one, it can be lighter.

Class D car amplifiers work on a relatively new type of amplifier design technology. They’re very efficient – in some cases up to nearly 90%! This contrasts with older designs which are around 65% efficient or less. What that means to you is they take up less space, generate less heat, draw less power, and often require smaller power wire.
Class AB VS Class D Amplifiers || Which one is right for me?
https://www.ctsounds.com/blogs/car-audio-education/class-ab-vs-class-d-amplifiers
About Class D Amplifiers. Class D amplifiers take it a step further and they are even more efficient, and less hot, than their AB counterparts. The transistors in class D amps will quickly switch back and forth from receiving power and being on, to receiving no power and being off. Being very efficient is a big plus when it comes to car audio ...

The class-D audio amplifier achieves a total root-mean-square (RMS) output power of 0.5W, a total harmonic distortion plus noise (THD+N) at the 8-Ω load less than 0.06%, and a power efficiency of 93%. The final design occupies approximately 1.5mm2.
