Non-Inverting Comparator with Hysteresis

Non inverting comparator with hysteresis requires a two re-

sistor network, and a voltage reference (V

ref) at the inverting

input. When V

in is low, the output is also low. For the output

to switch from low to high, V

in must rise up to Vin1 where Vin1

is calculated by

When V

in is high, the output is also high, to make the com-

parator switch back to it’s low state, V

in must equal Vref be-

fore V

a will again equal Vref.Vin can be calculated by:

The hysteresis of this circuit is the difference between V

in1

and V

in2.

∆V

in =VccR1/R2
