The LM393N IC is a Dual Comparator, featuring two individual precision voltage comparators. These comparators feature a remarkable offset voltage specification, offering as low as 2.0mV max for both comparators.

They function efficiently from a single power supply, accommodating a wide voltage range. Additionally, they can operate from split power supplies, and their low power supply current consumption remains unaffected by the power supply voltage level. These comparators possess a distinctive trait: their input common-mode voltage range encompasses ground, even when powered by a single supply voltage.

Applications include limit comparators, simple analog to digital converters; pulse, squarewave, and time delay generators; wide range VCO; MOS clock timers; multivibrators, and high voltage digital logic gates.
