Product Summary

The LM293DR2 is a Low Offset Voltage Dual Comparator. The LM293DR2 is capable of single or split supply operation. It is designed to permit a common mode range-to-ground level with single supply operation. Input offset voltage specifications as low as 2.0 mV make the LM293DR2 an excellent selection for many applications in consumer, automotive, and industrial electronics.
