Hi,

I plan to use the TLV1702 (or eq.) as a window comparator.

How do I add hysteresis to the window comparator?

Hi,

one way is to add resistors to the + inputs of comparators to provide individual hystereses, like shown here:

In addition to Kai's pictures, we have written two design cookbooks for adding hysteresis to circuits. Since the window comparator utilizes a non-inverting and inverting comparator configuration, you will need to use both of these for your design.
