Description

The LM3302 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. These were de- signed 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 characteris- ic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.
