AD590 Datasheet (Analog Devices) - 2-Terminal IC Temperature Transducer

AD590, 2-Terminal IC Temperature Transducer

The AD590 is a 2-terminal integrated circuit temperature transducer that produces an output current proportional to absolute temperature.

For supply voltages between 4 V and 30 V, the device acts as a high impedance, constant current regulator passing 1 μA/K.
