Question

Could you explain me what is the "input Current" named in the figure 5 of TS391 comparator datasheet compare to the input bias current and input offset current?

    Hi,

    This curve shows the input bias current. Which is the average current getting out of the input pins.

    Iib=(Iib+ + Iib-)/2. (when the op amp is used in linear, not as a comparator)

    The input offset current is the difference between the current off the two inputs. Iio=Iib+ - Iib-

    Best Regards,

    Pierre
