TL331-Q1 is typically used to compare a single signal to a reference or two signals against each other. Many users take advantage of the open collector output to drive the comparison logic output to a logic voltage level to an MCU or logic device. The wide supply range and high voltage capability makes TL331-Q1 an excellent choice for level shifting to a higher or lower voltage.
