AD590 produces the electric current and the absolute
temperature have the direct ratio, it may receive the working voltage
is 4V - 30V, the examination temperature range for - 55 鈩?- + 150
鈩? it has the extremely good linear output performance, the
temperature every time increases 1 鈩? its electric current increases
1uA.
