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 desi...
