MOTOROLA ANALOG IC DEVICE DATA

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 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.
