The AD590 is a monolithically integrated, two-terminal temperature-sensitive current source from ANALO G DEV ICES. AD590 measures the thermodynamic temperature, Celsius temperature, two-point temperature difference, multi-point minimum temperature, multi-point average temperature. It is widely used in different temperature control applications. Because AD590 has high precision, low price, no auxiliary power supply, and good linearity. Commonly used for temperature measurement and cold junction compensation of thermocouples.
