In the datasheet you can read things around temperature indication, device, signal conversion, loop, signal converter, temperature ranges, selection, temperature indication application, average temperature, voltage, and signal selection. This datasheet presents information like signal, supply, probe, output, output signals, signal conversion application, load, temperature, load resistors, current, and high impedance.
There are many explanation regarding resistors, channel signal, reference voltage, sensor, channel, transmitter, channel signal converter, application, controller, sensor application, and power supply are presented in this datasheet. The following are some excerpt from the datasheet:
The AD590 is a two-terminal integrated circuit temperature transducer which produces an output current proportional to absolute temperature. For supply voltages between +4V and +30V the device acts as a high impedance, constant current regulator passing 1mA/K. Laser trimming of the chip’s thin film resistors is used to calibrate the device to 298.2mA output at 298.2 Kelvin (+258C). The AD590 is particularly useful in remote sensing applications. The AD590 is insensitive to voltage drops over long lines due to its high impedance current output.
