Video Circuit Collection &mdash AN57
PDF, 559 Kb, 档案已发布: Jan 2, 1994
AN57, the Video Circuit Collection, features a variety of video circuits designed at LTC. The LT1204 70MHz multiplexer is featured in a number of circuits which require excellent video isolation from channel to channel. High speed voltage and current feedback amplifiers are highlighted throughout the section on video processing circuits. There is a section on applying Current Feedback Amplifiers (CFAs) and a number of articles taken from the Linear Technology magazine.

Application Note 57
January 1994
Video Circuit Collection
Jon Munson and Frank Cox
INTRODUCTION
Even in a time of rapidly advancing digital image processing, analog video signal processing still remains eminently
viable. The video A/D converters need a supply of properly
ampliп¬Ѓed, limited, DC restored, clamped, clipped, contoured, multiplexed, faded and п¬Ѓltered analog video before
they can accomplish anything. After the digital magic is
performed, there is usually more amplifying and п¬Ѓltering
to do as an adjunct to the D/A conversion process, not to mention all those pesky cables to drive. The analog way
is often the most expedient and efп¬Ѓcient, and you donвЂ™t
have to write all that code.
The foregoing is only partly in jest. The experienced engineer
will use whatever method will properly get the job done;
analog, digital or magic (more realistically, a combination
of all three). Presented here is a collection of analog video
circuits that have proven themselves useful. CIRCUIT INDEX
