Product overview
Description
The LM2903B consists of two independent low-power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. It is fully specified at 5 V and 36 V supply voltage operation, however operation from dual power supplies is also possible.
The B-grade version of the LM2903 comparators offers an increased maximum operating voltage of 40 V and improved electrical characteristics.
-
