description
The LP239, LP339, LP2901 are low-power quadruple differential comparators. Each device consists of four independent voltage comparators designed specifically to operate from a single power supply and typically to draw 60-µA drain current over a wide range of voltages. Operation from split power supplies is also possible and the ultralow power supply drain current is independent of the power supply voltage. Applications include limit comparators, simple analog-to-digital converters, pulse generators, squarewave generators, time delay generators, voltage controlled oscillators, multivibrators, and high-voltage logic gates. The LP239, LP339, LP2901 were specifically designed to interface with the CMOS logic family. The ultralow power supply current makes these products desirable in battery-powered applications. The LP239 is characterized for operation from - 25°C to 85°C. The LP339 is characterized for operation from 0°C to 70°C. The LP2901 is characterized for operation from - 40°C to 85°C.
The D package is available taped-and-reeled. Add R suffix to device type when ordering (e.g., LP339DR).
