The AD590 is a
temprature sensor. It has a
linear current vs
temperature change.
The
current that
flows through it changes 1
micro ampere
per
kelvin. This means that at 0
degrees celsius the
current is
273,2 uA. The AD590 has a
specified temperature range of
-55 to 150 C and a
voltage range of 4V to 30V. The
accuracy
is +- 1,5°C.
