Several analog value comparators can be used to evaluate different operating
states. In this case 3 different operating states are evaluated.
Parameter settings of three analog value comparators:
First operating state

To compare two analog values, you can use the following circuit. In this case,
the comparison determines whether I7 is less than I8.
