TI and Arrow to Present Live Analog eLab Webcast on Digital Audio Modulation Techniques

Webcast panelists will provide an overview of Class-D audio power amplifiers that use switched output devices to produce power with high efficiency. There are a variety of ways to control the switching
patterns. One technique that will be highlighted is Class-BD modulation, which permits operation without an output filter in many applications, thereby reducing cost and complexity.

In addition, panelists will discuss benefits of Class-D amplifiers and compare efficiency, heat generation and battery life with Class-AB amplifiers. Knowing the difference between the amplifiers is key to successful designs for handheld devices.

During the lab segments, Klein and Crump will demonstrate how to achieve EMC through a better understanding of electromagnetic interference (EMI) filter component characteristics and PCB layout principles. They will use a working EMI chamber to illustrate EMI testing.
