NJM12901
SINGLE SUPPLY QUAD COMPARATOR
■ GENERAL DESCRIPTION
The NJM12901 is single-supply quad voltage comparator,
which can operate from 2V supply. The features are low input
offset voltage, low input bias current and low current
consumption. The NJM12901 compare the input signal to 0V
( ground ) due to the Darlington PNP input stage.
The package lineup is DMP and others compact, so that the
NJM12901 is suitable for any kind of signal comparator.
