The UTC1517 is an integrated class-B dual output amplifier in a plastic single in-line medium power package with fin and a plastic heat-dissipating dual in-line package. The device is primarily developed for multi-media applications.

A Class-B dual output amplifier is an electronic amplifier configuration that utilizes two transistors, often one NPN (Negative-Positive-Negative) transistor and one PNP (Positive-Negative-Positive) transistor, to amplify an input signal. This configuration is also known as a push-pull amplifier and is commonly used in audio and radio frequency (RF) applications.

It’s worth noting that while Class-B amplifiers are efficient, they may not be as linear as Class-A amplifiers. To address crossover distortion and improve linearity, Class-AB amplifiers are commonly used in practice. These amplifiers operate in a manner that combines some of the characteristics of Class-A and Class-B amplifiers, offering improved linearity while maintaining relatively high efficiency.
