Analog Devices Inc. AD590 2-Terminal IC Temperature Transducers
Analog Devices AD590 2-terminal IC Temperature Transducers produce an output current proportional to absolute temperature. The devices act as a high impedance (>10MΩ), constant current regulator passing 1μA/K, specifically for supply voltages between 4V and 30V. The cost of a monolithic integrated circuit combined with the elimination of support circuitry makes AD590 ideal alternatives for many temperature measurement situations. AD590 can be used in any temperature-sensing application below 150°C in which conventional electrical temperature sensors are employed. AD590 are available in die form, making them suitable for hybrid circuits and fast temperature measurements in protected environments.
