Part Details:

LM2903EP March 2005 LM2903EP Low Low Power Low Offset Voltage Dual ComparatorsGeneral Description Advantages Power The LM2903EP consists of two independent precision volt- n High precision comparators age comparators with an offset voltage specification as low n Reduced V drift over temperature OS as 2.0 mV max for two comparators which were designed n Eliminates need for dual supplies specifically to operate from a single power supply over a n Allows sensing near ground Low wide range of voltages. Operation from split power supplies n Compatible with all forms of logic is also possible and the low power supply current drain is n Power drain suitable for battery operation independent of the magnitude of the power supply voltage.This comparator also has a unique characteristic in that the Offset input common-mode voltage range includes ground, even Features though operated from a single power supply voltage. n Wide supply Application areas include limit comparators, simple analog to -- Voltage range: 2.0V to 36V digital converters; pulse, squarewave and time delay gen- -- Single or dual supplies: ±1.0V to ±18V V erators; wide range VCO; MOS clock timers; multivibrators n Very low supply current drain (0.4 mA) -- independent oltage and high voltage digital logic gates. The LM2903EP was of supply voltage designed to directly interface with TTL and CMOS. When n Low input biasing current: 25 nA operated from both plus and minus power supplies, the n Low input offset current: ±5 nA LM2903EP will directly interface with MOS logic where their n Maximum offset voltage: ±3 mV low power drain is a distinct advantage over standard com- Dual n Input common-mode voltage range includes ground parators. n Differential input voltage range equal to the power ENHANCED PLASTIC
