NJM12903
SINGLE SUPPLY DUAL COMPARATOR
■
GENERAL DESCRIPTION
The NJM12903
is single-supply dual voltage comparator,
which can operate from 2V supply. The features are input
offset voltage, input bias current and low current consumption.
The NJM12903
compare the input signal to 0V(ground)
due to the Darlington PNP input stage. The package lineup is
DIP, DMP and others compact, which is SON, so that the
NJM12903
is suitable for any kind of signal comparator.
