The AD590JH is a 2-terminal integrated circuit temperature sensor that produces an output current temperature proportional to its absolute value. For supply voltages between 4 V and 30 V, the device acts as a high impedance, constant current regulator through 1 μA/K. The device was calibrated to an output of 298.2 μA at 298.2 K (25°C) using the thin film resistance of the laser trimmed chip.

The AD590JH should be used in any temperature sensing application below 150°C where conventional electrical current temperature sensors are employed. The inherent low cost of a monolithic integrated circuit combined with elimination of support circuitry makes the AD590 an attractive alternative for many temperature measurement situations. Linearization circuits, precision voltage amplifiers, resistance measurement circuits, and cold junction compensation are not required for the application of the AD590.

AD590JH In addition to temperature measurement, applications include temperature compensation or correction of discrete components, offset proportional to absolute temperature, flow measurement, fluid level detection, and wind velocity measurement. The AD590 is available in die form, making it suitable for hybrid circuits.
