LM2903DR2G is a dual channel, independent precision low offset voltage comparator that can be powered by a single or separate power source. This device is designed to allow for a common mode range to ground level with a single power supply. The input offset voltage specification as low as 2.0mV makes this device an excellent choice for many applications in consumer electronics, automotive, and industrial electronics.
