LP2901

Product Summary

The LP2901 is a low-power quadruple differential comparator. It consists of four independent voltage comparators designed specifically to operate from a single power supply and typically to draw 60-mA 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 LP2901 was specifically designed to interface with the CMOS logic family. The ultralow power supply current makes these products desirable in battery-powered applications. The LP2901 is characterized for operation from -40℃ to 85℃.
