TI and Avnet Electronics Marketing Present Analog eLab Webcast on High-Speed Operational Amplifiers

Dec 5, 2005

DALLAS (December 5, 2005) - Analog design engineers are invited to register at www.ti.com/analogelab for a live Analog eLab Webcast entitled "Voltage Feedback and Current Feedback Op Amps in High-Speed Applications: Pros, Cons and Design Tricks." Presented by Texas Instruments Incorporated (TI) (NYSE:TXN) and Avnet Electronics Marketing, a division of Avnet, Inc. (NYSE:AVT), the Webcast will air at 11:00 a.m. CDT (18.00 hrs CET) on Wednesday, December 14, 2005. TI analog expert Bill Klein, P.E., guest engineers Michael Steffes and Xavier Ramus of TI, and Mike Claassen of Avnet will provide designers with an online discussion on high-speed operational amplifiers (op amps) for high frequency designs.
High-speed op amps fall into two classes based on their internal design: the current feedback and the more common voltage feedback. During the hour-long session, design engineers will hear about the basic differences in the design topology of these op amps and the importance it plays with the external application circuits. The eLab engineers will discuss various applications and offer advice on which device is more suited for specific designs.
During the lab segment, Klein, Steffes and Ramus will demonstrate how to use lab equipment similar to that used in characterizing these op amps and will show how to measure several key performance characteristics. The engineers will also share some useful design tricks. In addition, the lab session will cover pulse response, slew rate and distortion measurement as well as full power bandwidth and bandwidth control.

Analog eLab Design Engineers

Bill Klein, P.E. is the host for the TI Analog eLab Webcast. Klein is a senior applications engineer with the high performance linear division of TI. He joined TI through its acquisition of Burr-Brown in August 2000. Klein is the author of over 50 magazine articles, application notes and conference papers. His experience as an analog circuit designer covers 30 years in fields ranging from mineral exploration to medical nuclear imaging.

Michael Steffes is the market development manager for the high-speed signal conditioning group of TI in Tucson and is a distinguished member of technical staff. He has 24 years of experience with high-speed amplifier design, applications and marketing, and has written more than 85 product data sheets, published numerous contributed articles and applications notes, and presented nearly a dozen conference papers. Steffes also shares several basic patents in high-speed op amp design.

Xavier Ramus is an applications engineer in TI's high-speed signal conditioning group. With nearly ten years of experience, Ramus works with new product introductions, provides support for customer designs and develops presentation material for training in high performance analog. His particular area of interest is the interfacing of high-speed amplifiers to high-speed data converters. Ramus earned a MSEE from San Jose State University.

Mike Claassen is a technology director with Avnet, Inc. Previous to his seven years in distribution, Claassen was a design engineer for an industrial control company. His experience includes hardware, software and system design. In addition, he has authored various application notes and created and delivered hands-on technical training. Claassen holds a BSEE from Kansas State University.
