The AD590 is a small IC temperature sensor that converts a temperature input into a proportional current output.
The advanced technology in the AD590 is especially suited for special temperature measurement and control applications between –55 and 150°C when solid state reliability, linearity and accuracy are required. The AD590 temperature sensor can be used to determine minimum, average, and differential temperatures, in addition to being used for thermocouple cold junction compensation and temperature control applications. The size and responsiveness of the AD590 IC Sensor makes it perfect for uses where size is a consideration, such as on PC boards or heat sinks.
Just power up and measure absolute temperature (Kelvin). No linearization, amplification or cold junction compensation is required.
