LM2901EP
Low Power Low Offset Voltage Quad Comparators
General Description
The LM2901EP 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
independent of the magnitude of the power supply voltage.
This comparator also has 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 LM2901EP was
designed to directly interface with TTL and CMOS. When
operated from both plus and minus power supplies, it will
directly interface with MOS logic — where the low power
drain of the LM2901EP is a distinct advantage over standard
comparators.
