SINGLE SUPPLY, LOW POWER  
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.
