The Class D amplifier topology theoretically offers ideal characteristics for audio: 100% efficiency, 0% THD, and no audible noise. While practical Class D implementations can come attractively close ...
Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...
There are two salient facts about Class A amplifiers: they are inefficient; they give the best possible distortion performance. The quiescent dissipation of the classic Class A amplifier is equal to ...
“Class” is in session. This discussion of electronic amplifier circuits offers an overview of the characteristics that define commonly used class designations ...
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 ...
