New Japan Radio NJM2903CA
NJM2903C / NJM2903CA
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

NJM2903CAG
(SOP8)
NJM2903CRB1
NJM2903CARB1
(MSOP8(TVSP8)
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

(Note1) The NF pin, NC pin and The PAD have to be wired as short as possible to
connect with a Vpin.
(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.
