Comparator hysteresis can be increased with the addition of
resistor R H . The hysteresis equations have been simplified and
do not account for the change of input current I in as V in crosses
the comparator threshold. The internal resistance, R in is simply
calculated using I in = 0.26 m A at 2.6 V.
