Intersil AD590 2-Wire Current Output Temperature Transducer Datasheet
The Intersil AD590 is an integrated-circuit temperature transducer that produces an output current proportional to absolute temperature. It acts as a high impedance constant current regulator, passing 1µA/oK for supply voltages between +4V and +30V. The device is calibrated to 298.2µA output at 298.2 oK (25°C) via laser trimming of the chip's thin film resistors.
