rail to rail
A hot topic with single-supply operational amplifiers is whether
they have rail-to-rail input or output operation capability.
While some amplifiers on the market are able to accept input
voltages from one rail to the other rail, this is achieved with
a few compromises in performance. Single-supply amplifier
manufacturers also claim they have devices that will swing railto-
rail on the output. With these types of amplifiers, the output
cannot go all the way to the rails, though it can get close. This
Analog Design Note briefly shows the actual performance of
some of the more popular single-supply amplifiers.
