NJM12901 SINGLE SUPPLY QUAD COMPARATOR GENERAL DESCRIPTION PACKAGE OUTLINE 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 NJM12901V NJM12901M ( 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.
