What does "rails" mean?
For example:
"5V at the rails"
"rail to rail amplifiers"
"As for current delivery, most will do a few milli-amps, but
typically not near the rails"
"an opamp with a symmetric output swing at each rail"
"as long as your supply rails were properly adjusted."
"This pretty much slams the square right up to the rails"
Thanks,
JP
