OPA627, 637
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.
FIGURE 9. OPA627 Dynamic Performance, G = –1.
NOTE: (1) Optimum value will
depend on circuit board lay-
out and stray capacitance at
the inverting input.
