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.
