NJM12903
SINGLE SUPPLY DUAL COMPARATOR
■ GENERAL DESCRIPTION
■ PACKAGE OUTLINE
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
