Low Power Low Offset Voltage Quad Comparators
General Description
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.
