Product Summary

The LM2903DR is a dual differential comparator. 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. The LM2903DR consists of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. The LM2903DR is characterized for operation from -25℃ to 85℃.
