NOTE: (1) Optimum value will
depend on circuit board lay-
out and stray capacitance at
the inverting input.
When driven with a very fast input step (left), common-mode
transients cause a slight variation in input stage currents which
will reduce output slew rate. If the input step slew rate is reduced
(right), output slew rate will increase slightly.
