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.
