The STMicroelectronics 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. Wide single supply voltage range or dual supplies +2 V to +36 V or ±1 V to ±18 V
Very low supply current 0.5 mA typ., essentially independent of supply voltage
Low input bias current of 20 nA typ
