Texas Instruments and Arrow Electronics Present Live Analog eLab Webcast on Digital Audio Modulation Techniques
Share:
DALLAS (August 23, 2006) - Texas Instruments Incorporated (TI) (NYSE: TXN) and Arrow Electronics, Inc. (NYSE: ARW) will present a live Analog eLab Webcast for designers entitled "Class-D Audio Power Amplifiers: Operation, Efficiency and EMC" on Wednesday, September 6, 2006, at 11:00 a.m. CDT (18:00 hrs CET). During the online discussion, TI analog expert Bill Klein, P.E., and eLab panelists Stephen Crump of TI and David Schmidt of Arrow will talk about the operation and efficiency of Class-D amplifiers with special focus on Class-BD modulation. In addition, they will discuss elements of electromagnetic compatibility (EMC) testing, filter component characteristics and proper PCB layout. Engineers are invited to register for the one-hour session at www.ti.com/analogelab.
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.
