Low Power Dual Voltage Comparator - LM393N / LM339
Description:
These are very commonly used low voltage comparators in electronic projects. They are good quality and cost effective. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.
