Product Summary
The LM393M is a Low Power Low Offset Voltage Dual Comparator. The LM393M consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were de-signed specifically to operate from a single power supply over a wide range of voltages. 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. The LM393M also has a unique characteris-tic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.
