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.
The document details three low-power quadruple differential comparator models: the LP239, LP339, and LP2901. These devices are specifically designed to operate from a single power supply and draw ultralow drain current, making them suitable for battery-powered applications. They feature pin-for-pin compatibility with the LM239, LM339, and LM2901 series.
