This is a simple Inverter Window Comparator Circuit Diagram ICl-c
functions as a non inverting comparator, and ICl-a operates as an
inverting comparator. Potentiometer Rl and fixed resistors R2 and R3
form a divider chain that delivers slightly different voltages to the
two comparators. These voltages define the upper and lower limits of the
circuit`s switching window, which can be changed easily by varying R2
and R3. The LED glows only when the input voltage falls within the
window region.
