The FAN156 is a low-power single comparator that typically consumes less than 10µA of supply current. It is guaranteed to operate at a low voltage of 1.6V and is fully operational up to 5.5V, making it convenient for use in 1.8, 3.0V, and 5.0V systems.The FAN156 has a complementary push-pull P- and N-channel output stage capable of driving a rail-to-rail output swing with a load ranging up to 5.0mA.
