Overview
The LM2901HYDT 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 power supply over a wide range of voltages, from +2 V to +36 V, or from dual supplies ranging from ±1 V to ±18 V. The comparators are notable for their ability to operate with an input common-mode voltage range that includes ground, even when powered by a single supply voltage.
