The LM393 series are dual independent precision voltage comparators capable of single or split supply operation. These devices are 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.
