Features
Description
This device consists of four independent precision
voltage comparators. All these comparators 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 ground even though
operated from a single power supply voltage.
