LP339 Ultra-Low Power Quad Comparator

The LP339 consists of four independent voltage comparators designed specifically to operate from a single power supply and draw typically 60 µA of power supply drain current over a wide range of power supply voltages. Operation from split supplies is also possible and the ultra-low power supply drai.
