LM393, LM393A, LM293, LM2903, LM2903V Low Offset Voltage Dual Comparators
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 range­to­ground 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. · Wide Single­Supply Range: 2.0 Vdc to 36 Vdc
