High-Efficiency Class D Audio Amplifiers | Maxim Integrated
https://www.maximintegrated.com/en/design/technical-documents/tutorials/1/1760.html
Power-hungry linear amplifiers have long dominated the world of audio. But as consumers of portable electronics demand smaller devices with longer battery life, designers are replacing conventional linear amplifiers with high-efficiency devices. Switching audio has thus found a niche. Although Class AB amplifiers dominate the world of audio, Class D (switch-mode) …
