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.
