Editor's Note: Class D amplifiers are often considered THE solution for most applications – without full engineering analysis. In this series Robert Polleros of Maxim Integrated Products Inc. takes on ...

Different classes of amplifiers. What are the benefits of class AB amplifiers? Patents that address the quiescent current of class AB amps. Amplifiers have many classifications, and each class has its ...

The NCP2991 class AB audio amplifier from ON Semiconductor addresses two crucial requirements in today’s portable and wireless audio applications: noise-free audio amplification and fast response time ...

[Dino Segovis] wrote in to tell us about his “hack”, making an AB Audio Amplifier. The advantage of this particular amp is that the transistors never turn off, which would cause distortion. A full ...

Looking for a cool running new amplifier? Outlaw Audio's Model 7220 is a seven channel class AB fully balanced amp rated to deliver 220W per channel into an 8-ohm load with all seven channels driven.

Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...
