Overview
MA139/239/339 • MA139A/239A/339A MA2901 • MA3302 LOW-POWER, LOW-OFFSET VOLTAGE QUAD COMPARATORS FAIRCHILD LINEAR INTEGRATED CIRCUITS GENERAL DESCRIPTION - The I"A139 series consists of four independent precision voltage comparators designed specifically to operate from a single power supply.
Operation from split power supplies is also possible and the low power supply current drain is independent of the supply voltage range.
Darlington connected PNP input stage allows the input common-mode voltage to include ground.
