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…

The TDA7491P is a dual BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors. Thanks to the high efficiency and exposed-pad-down (EPD) package no separate heatsink is required. Furthermore, the filterless operation allows a reduction in the external component count.

This article describes how to design a simple class D power amplifier using the High Voltage GreenPAK™ IC. A class D amplifier operates by deriving a two-state signal from a continuous control signal and amplifying it using power switches. At the core of every class D amplifier is at least one comparator and one switching power stage. In all but the lowest-cost …

https://www.nordacoustics.co.uk/product-page/nord-one-se-mp-nc500-stereo-power-amp-in-black It's amazing the power and transparency that is now available compared to only a few years ago due to the improvement in D Class amps and Chinese DACs. I would argue you can now obtain a very transparent "HiFi" front end (Streamer, Topping 50s DAC & Nord …
