calculated by:
IN
When V
The total hysteresis provided by the network is defined as:
To assure that the comparator will always switch correctly, the resistors values should be chosen as follow:
R
It requires a two resistor network to implement a non inverting comparator with hysteresis and with a voltage
When V
The hysteresis of this circuit is the difference between V
must rise up to V
