The LM2901 Quad Differential Voltage Comparator is designed to operate over a wide range of voltage but from a singular power supply. It’s also possible to operate it from split power supplies. The LM2901 uses 2 and 4 precision voltage comparators that have low input voltage requirements. Its power supply current is also low irrespective of the power supply voltage’s magnitude.
These comparators have been designed to interface directly with CMOS and TTL and can operate from both minus and plus power supplies. This kind of low power drain makes them more preferable than other competitors. Their standard compound is green mold.
