Texas Instruments Incorporated (TI) (NYSE: TXN) and Arrow Electronics Inc. (NYSE: ARW) will present a live Analog eLab(TM) Webcast for designers titled “Improved Voltage Reference Circuits Maximize Converter Performance” on Wednesday, September 12, 2007, at 11:00 a.m. CDT (18:00 hrs CET). The webcast will highlight how reference accuracy is a major factor in the overall accuracy of the data conversion. During the webcast, TI analog expert Bill Klein, P.E., and eLab panelists Miro Oljaca of TI and Peter Goad of Arrow will discuss noise reduction techniques and various circuit topologies for stabilizing output voltage accuracy and offer tips on maximizing performance. Engineers are invited to register for the one-hour session.
Analog-to-digital converter (ADC) and digital-to-analog converter (DAC) performance is directly tied to the operation of the associated voltage reference. Data converters present a unique current demand load for the reference buffer amplifier. The Analog eLab panelists will provide an understanding of the load dynamics necessary to ensure that the proper drive is supplied. They will also cover effective ways to maintain stable voltage reference output and avoid degradation of the output voltage accuracy.
During the lab session, the panelists will use FFT and histogram plots of ADC outputs to demonstrate circuit performance improvements. Viewers will be shown techniques for overcoming buffer amplifier stability issues and achieve noise reduction.
