Low Power Low Offset Voltage Dual Comparators
General Description
The LM2903EP consists of two independent precision volt-
age comparators with an offset voltage specification as low
as 2.0 mV max for two comparators which 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. 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 gener-
ators; wide range VCO; MOS clock timers; multivibrators and
high voltage digital logic gates. The LM2903EP was designed
to directly interface with TTL and CMOS. When operated from
both plus and minus power supplies, the LM2903EP will di-
rectly interface with MOS logic where their low power drain is
a distinct advantage over standard comparators.
