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.
