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.

3. Due to the PNP transistor inputs, bias current will flow out of the inputs. This current is essentially constant, independent of the output state, there  
fore, no loading changes will exist on the input lines.  
4. Input common mode of either input should not be permitted to go more than 0.3 V negative of ground or minus supply. The upper limit of common  
mode range is V  
–1.5 V.  
CC  
5. Response time is specified with a 100 mV step and 5.0 mV of overdrive. With larger magnitudes of overdrive faster response times are obtainable.  
6. The comparator will exhibit proper output state if one of the inputs becomes greater than V , the other input must remain within the common mode  
CC  
range. The low input state must not be less than –0.3 V of ground or minus supply.
