NJM12903
SINGLE SUPPLY DUAL COMPARATOR
■ GENERAL DESCRIPTION
The NJM12903 is a 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. In addition, small packages
TVSP, VSP and SSOP are available. The NJM12903 is suitable
for any kind of signal comparator.
