Overview
The LM2901YDT, produced by STMicroelectronics, is a low-power quad voltage comparator. 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 input common-mode voltage ranges that include the negative rail, even when powered by a single supply voltage.
