2) The slew rate specifications are not warranted but are descriptions of typical performance. The actual transition
time is defined as the time for the input to change from 10% to 90%, or vice versa, of the programmed current
values. In case of very large load changes, e.g. from no load to full load, the actual transition time will be larger
than the expected time. The load will automatically adjust the slew rate to fit within the range (high or low)
that is closest to the programmed value.
