LP339N .

The LP339N is an ultra-low power Quad Comparator designed specifically to operate from a single power supply and draw typically 60µA 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 drain current is independent of the power supply voltage. This comparator also features a common-mode range which includes ground, even when operated from a single supply. The LP339 was specifically designed to interface with the CMOS logic family. The ultra-low supply current makes the LP339 valuable in battery powered applications.
