Description

The NJM390A/NJM391A are single comparator designed specifically to

operate from a single supply over a wide range of voltages. Operation from split

power supplies is also possible.

The NJM390A/391A also have a unique characteristic in that the input

common-mode voltage range includes ground even though operated from a

single power supply voltage.
