description/ordering information
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 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, squarewave
generators, time-delay generators, voltage-controlled oscillators, multivibrators, and high-voltage logic gates.
The LP239, LP339, LP2901 were designed specifically to interface with the CMOS logic family. The ultra-low
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.
