1. Question:
How much das the hysteresis spread from chip to chip when using a resistor to
programm the "Ihys"?
2. Question:
Is the hysteresis dependent on the input voltage of the comparator?

 

The amount of hysteresis is not trimmed in any way and can vary +/- 25% lot to
lot.

There are temperature effects as well, so if high precision is needed some sort
of calibration should be used.
