1. A system for supplying a current or a voltage to a load in response to an input signal or value, comprising:
an output driver for supplying the current or the voltage to the load;
a first control path that receives the input signal or value and has an output coupled to an input of the output driver;
a second control path that receives the input signal or value and has an output coupled to the input of the output driver;
a control circuit that selects between the first control path and the second control path in response to a path selection indication to provide the output to the input of the output driver; and
an evaluator that receives the input signal or value and determines the path selection indication conditioned on both of an amplitude and a slew rate at which the input signal or value is transitioning to a next value.
