Overview
The LM2901YPT is a low-power quad voltage comparator produced by STMicroelectronics. This device consists of four independent precision voltage comparators designed to operate from a single supply over a wide range of voltages, as well as from split power supplies. The comparators are notable for their ability to operate with an input common-mode voltage range that includes the negative rail, even when using a single power supply voltage.
