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?

Could you explain me what is the "input Current" named in the figure 5 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
