* NJM2903CMD7 don’t have a A version.
(Note1) The NF pin, NC pin and The PAD have to be wired as short as possible to connect with a V− pin.
(Note2) The NF pin and The PAD are electronically connected to the backside of the die. But, there cannot be used as V- pin.
(Note3) The NC pin is not internally connected.

SINGLE-SUPPLY DUAL COMPARATOR ■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE The NJM2903C / NJM2903CA consist of two independent voltage comparators that are 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. The NJM2903C / NJM2903CA has a unique characteristic: 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, square-wave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The NJM2903C / NJM2903CA were designed to directly interface with TTL and MOS. When operated from both plus and minus power supplies, the NJM2903C / NJM2903CA will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators ■ FEATURES ● Operating Voltage +2V to +36V ● Single Supply Operation ● Open Collector Output ● Package Outline SOP8,DMP8,SSOP8 ,EQFN14-D7
