Description

The LM193, LM293, and LM393 devices consist

of two independent low voltage comparators

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.
