Rail To Rail Op Amp Meaning. Just as a train s rails place limits on the lateral movement of a train op amp power rails place limits on the voltage swing at the input and output. Same goes for inputs.
15v can only drive the output to within 3 or 4 volts of the rail for example with a bipolar 15 volt supply the amp may only be able to drive up to 12v. What does thisassertion really mean. Compared against state of the art amplifier designs.
Same goes for inputs.
Compared against state of the art amplifier designs. Page one of a single supply op amp sdata sheet may call out rail to rail input output swing inthe title or bullets.
