DESCRIPTION

The LM2901EP 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. 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 generators; 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.
