                                                                                                  LM2903ATH-13 is a dual-channel device that consists of two independent precision voltage comparators with a very low input offset voltage specification. This is designed to operate from a single power supply over a wide range of voltages; however, operation from split power supplies is also possible. This offers a low power supply current independent of the magnitude of the power supply voltage. It is designed to directly interface with TTL and CMOS. When operating from both plus and minus power supplies, the LM2903 series comparator will directly interface with MOS logic, where its low power drain is a distinct advantage over standard comparators.
