Working Principle

The ICL7641CCPD+ is a voltage comparator that operates according to the following principle: when the common mode input voltage of the comparator is higher than the reference voltage applied to the non-inverting input terminal, the output of the comparator is pulled high and the output voltage is equal to the supply voltage. Conversely, when the common mode input voltage is lower than the reference voltage applied to the non-inverting input terminal, the output of the comparator is pulled low and the output voltage is approximately equal to ground. This process of comparing two voltages is used to determine whether one voltage is higher or lower than another, and is known as a “comparator”.
