ABSTRACT:
A circuit and method for controlling a slew rate of an output buffer. A pre-driver is provided that drives an input of an output pad driver of the output buffer. An output slew rate of the pre-driver is electronically selected among at least two electronically selectable slew rates. An output amplitude of the pre-driver is controlled such that the output amplitude is not greater than an amplitude that is generally minimally sufficient to cause the output pad driver to produce an output signal having a desired dynamic range.
