SN391Low Power Single Comparator
Description
The SN391 consists of single voltage comparators designed to
operate from a single power supply over a wide voltage range.
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 though
they are operated from a single power supply voltage.
