Description
The FAN256 is a low-power, dual comparator that
typically consumes less than 10µA supply current per
comparator. Guaranteed to operate at a low voltage of
1.6V and fully operational up to 5.5V, it is convenient for
use in 1.8, 3.0V, and 5.0V systems.
The FAN256 has a complementary push-pull P- and N-
channel output stage capabile of driving a rail-to-rail
output swing with a load ranging up to 5.0mA.
