INTRODUCTION
Application Note 87 is the fifth in a series that excerpts
useful circuits from Linear Technology magazine to preserve them for posterity. This application note highlights
data conversion, interface and signal conditioning circuits
from issue VI:1 (February 1996) through issue VIII:4
(November 1998). Like its predecessor, AN67, this Application Note includes circuits for high speed video, interface and hot swap circuits, active RC and switched capacitor filter circuitry and a variety of data conversion and instrumentation circuits. There are also several circuits
that cannot be so neatly categorized. So, without further
ado, I’ll let the authors describe their circuits.
Note: Article Titles appear in this application note exactly
as they originally appeared in Linear Technology magazine. This may result in some inconsistency in the usage
of terminology. TABLE OF CONTENTS
