Low Power Low Offset Voltage Quad Comparators  
General Description  
Features  
The LM139 series consists of four independent precision volt-  
age comparators with an offset voltage specification as low  
as 2 mV max for all four comparators. These were designed  
specifically to operate from a single power supply over a wide  
range of voltages. Operation from split power supplies is also  
possible and the low power supply current drain is indepen-  
dent of the magnitude of the power supply voltage. These  
comparators also have a unique characteristic in that the input  
common-mode voltage range includes ground, even though  
operated from a single power supply voltage.

Application areas include limit comparators, simple analog to  
digital converters; pulse, squarewave and time delay gener-  
ators; wide range VCO; MOS clock timers; multivibrators and  
high voltage digital logic gates. The LM139 series was de-  
signed to directly interface with TTL and CMOS. When oper-  
ated from both plus and minus power supplies, they will  
directly interface with MOS logic— where the low power drain  
of the LM139/LM139A is a distinct advantage over standard  
comparators.
