Description

This

device

consists

of

four

independent

precision voltage comparators. All comparators

are designed specifically to operate from a single

power 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.
