Product Summary
The LM2903N is a dual differential comparator. The LM2903N consists of two 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 LM2903N is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.
Parametrics
LM2903N absolute maximum ratings: (1)Supply voltage, VCC: 36 V; (2)Differential input voltage, VID: ±36 V; (3)Input voltage range, VI (either input): 0.3 V to 36 V; (4)Output voltage, VO: 36 V; (5)Output current, IO: 20 mA; (6)Duration of output short-circuit to ground: Unlimited.
