National Semiconductor LM339M Quad Comparator (SMD)

Comparators – National Semiconductor LM339M, The LM139 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2mV for all four comparators. These were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even when operated from a single power supply voltage. Application areas include limit comparators, simple analogue to digital converters and time delay generators. National Semiconductor LM339M Quad Comparator (SMD)
