DESCRIPTION

This device consists of four independent precision

voltage comparators. All these comparators were

designed specifically to operate from a single

power supply over a wide range of voltages. Oper-

ation from split power supplies is also possible.

These comparators also have a unique character-

istic in that the input common-mode voltage range

includes ground even though operated from a sin-

gle power supply voltage.
