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.
