NJM12903
SINGLE SUPPLY DUAL COMPARATOR
■
GENERAL DESCRIPTION
The NJM12903 is single-supply dual voltage comparator,
which can operate from 2V supply. The features are low input
offset voltage, low 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, so that the NJM12903 is suitable for
any kind of signal comparator.
