●Example of circuit

○Reference voltage is Vin-

While input voltage is bigger than reference voltage, output

voltage is high. While input voltage is smaller than reference

voltage, output voltage is low.

○Reference voltage is Vin+

While input voltage is smaller than reference voltage, output

voltage is high. While input voltage is bigger than reference

voltage, output voltage is low.
