轨到轨：铁路建设和电子运算放大器

摘要：铁路已经有多年了，其实，近轨到轨的轨到轨组件。运算放大器采用相同的近轨到轨的传统。本应用笔记讨论了轨至轨运算放大器，并解释了为什么一些输入和输出可以是小于，接近或略高于电源轨。

APPLICATION NOTE 4428
Rail-to-Rail: Railroading and the Electronics of Op Amps
By:Bill Laumeister, Strategic Applications Engineer


Abstract:Railroads have had rail-to-rail components for years that were, in fact, nearly rail to rail. Op amps employ the same
nearly rail-to-rail tradition. This application note discusses rail-to-rail op amps, and explains why some inputs and outputs can be
less than, nearly, or slightly more than the power rails.
