Circuit Graph

When the position (percentage) of the wiper of potentiometer Rref1 is higher than the position (percentage) of the wiper of potentiometer Rref2, the circuit operates as an active high range comparator. When the input signal is both higher than the reference voltage of the bottom comparator AND lower than the reference voltage of the top comparator the voltage at the output/load is high. Otherwise (when the input signal is outside of the range of the two reference voltages), the voltage at the output/load is low. When the position (percentage) of the wiper of potentiometer Rref1 is lower than the position (percentage) of the wiper of potentiometer Rref2, the voltage at the output/load will always be low. This is because the active (high) state of the output of the two comparators do not overlap.
