Description
This device consists of four independent precision
voltage comparators, which are designed
specifically to operate from a single supply over a
wide range of voltages. Operation from split
power supplies is also possible.
These comparators also have a unique
characteristic in that the input common-mode
voltage range includes the negative rail even
though operated from a single power supply
voltage.
