NXP Semiconductors N.V. has enhanced its family of Class-AB audio amplifiers, providing improved quiescent current reduction and decreased smart phone signal interference. The integrated GSM input ...

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 ...

[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 ...

Here is a 2W Class-AB audio power amplifier which provides low harmonic distortion (≈ 1.5%) and wide frequency response. It is also capable of driving an 8Ω loudspeaker with an output power of 5W but ...
