The AD590 is a two-terminal integrated circuit temperature
transducer that produces an output proportional to
absolute temperature. For supply voltages between +4 V
and +30 V the device acts as a high impedance, constant
current source supplying 1 mA/K. Laser trimming of the
chip’s thin-film resistors is used to calibrate the device
to an output of 298.2 mA at 298.2K (+25°C).
