Product Summary
The LM393N is a dual independent precision voltage comparator capable of single or split supply operation. The LM393N 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 this device an excellent selection for many applications in consumer automotive, and industrial electronics.
