The LND393 consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators. They are specifically designed to operate from a single power supply over a wide range of voltages. In addition, the comparators have the unique ability in that the input common-mode voltage range includes ground, while operated from a single power supply voltage. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
