The active components of the Class D amplifier are the switching output stage and modulator. This circuitry can be built for roughly the same cost as an analog linear amplifier. The real trade-offs ...
Due to their small physical size and high energy efficiency, Class D amplifiers have become fixtures in smartphones and battery-driven artificial intelligence (AI) speakers, where space and power are ...
Starke Sound’s new AD4.320 4-channel power amplifier ($1,399) uses a home-grown Class D amplifier module combined with an old-school linear power supply. It can be bridged for up to 650 watts!
This article was originally published in the Dec 14, 1998 issue of Electronic Design. Class-D audio power amplifiers (APAs) were first introduced nearly 50 years ago. Since then, they have been used ...
The efficiency and size advantages of Class D audio amplification in battery- powered devices are well known. These advantages are now extended to amplifiers up to 500W, made possible by solidstate ...
