The LP2901 is a low-power quadruple differential comparator. The 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 also is possible, and the ultra-low power-supply drain current is independent of the power-supply voltage.
Applications include limit comparators, simple analog-to-digital converters, pulse generators, square-wave generators, time-delay generators, voltage-controlled oscillators, multivibrators, and high-voltage logic gates. The LP2901 is designed specifically to interface with the CMOS logic family. The ultra-low power-supply current makes these products desirable in battery-powered applications.
The LP2901 is characterized for operation from ?40°C to 85°C.
