LM139/LM239/LM339/LM2901/LM3302  
Low Power Low Offset Voltage Quad Comparators  
General Description  
Features  
n Wide supply voltage range  
n LM139/139A Series  
n LM2901:  
The LM139 series consists of four independent precision  
voltage 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 independent of the magnitude of the power supply  
voltage. These comparators also have a unique characteris-  
tic in that the input common-mode voltage range includes  
ground, even though operated from a single power supply  
voltage.  
2 to 36 VDC or 1 to 18 VDC  
2 to 36 VDC or 1 to 18 VDC  
2 to 28 VDC or 1 to 14 VDC  
n LM3302:  
n Very low supply current drain (0.8 mA) — independent  
of supply voltage  
n Low input biasing current:  
n Low input offset current:  
25 nA  
5 nA  
3 mV  
n Offset voltage:  
n Input common-mode voltage range includes GND  
n Differential input voltage range equal to the power  
supply voltage  
n Low output saturation voltage:  
n Output voltage compatible with TTL, DTL, ECL, MOS  
Application areas include limit comparators, simple analog to  
digital converters; pulse, squarewave and time delay gen-  
erators; wide range VCO; MOS clock timers; multivibrators  
and high voltage digital logic gates. The LM139 series was  
designed to directly interface with TTL and CMOS. When  
operated from both plus and minus power supplies, they will  
directly interface with MOS logicwhere the low power  
drain of the LM339 is a distinct advantage over standard  
comparators.  
250 mV at 4 mA  
and CMOS logic systems  
Advantages  
n High precision comparators  
n Reduced VOS drift over temperature  
n Eliminates need for dual supplies  
n Allows sensing near GND  
n Compatible with all forms of logic  
n Power drain suitable for battery operation
