Product Summary
The LM2901DR is a quad differential comparator, which consists of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible, as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain of the LM2901DR is independent of the supply voltage. The LM2901DR outputs can be connected to other open-collector outputs to achieve wired-AND relationships.
