Low Power Low Offset Voltage Quad Comparators
General Description
The LM139 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 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 gen-
erators; wide range VCO; MOS clock timers; multivibrators
and high voltage digital logic gates. The LM139 was de-
signed to directly interface with TTL and CMOS. When op-
erated from both plus and minus power supplies, they will
directly interface with MOS logic— where the low power
drain of the LM139 is a distinct advantage over standard
comparators.
