Rail-to-Rail: Railroading and the Electronics of Op Amps


摘要 : 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.
