... The AD590 is a 2-terminal integrated circuit temperature trans- ducer 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. Laser trimming of the chip’s thin-film resistors is used to calibrate the device to 298.2 μ ...

... The AD590 was used at −100°C and +200°C for short periods of measurement with no physical damage to the device. However, the absolute errors specified apply to only the rated performance temperature range. ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection ...

... Kelvin. This scale factor is trimmed to 1 μA/K at the factory, by adjusting the indicated temperature (that is, the output current) to agree with the actual temperature. This is done with 5 V across the device at a temperature within a few degrees of 25°C (298.2K). The device is then packaged and tested for accuracy over temperature. ...

... AD590 H package in a stirred bath at 25°C, when driven with supply, is 0.06°C. However, for the same conditions in still air, the temperature rise is 0.72°C. For a given supply voltage, the temperature rise varies with the current and is PTAT. Therefore application circuit is trimmed with the ...

... Air velocity @ 9 ft/sec. 3 The time constant is defined as the time required to reach 63. instantaneous temperature change. The time response of the AD590 to a step change in temperature is determined by the thermal resistances and the thermal capacities of the chip and the case about 0.04 Ws/°C for the AD590. C ...

... AD590 GENERAL APPLICATIONS Figure 16 demonstrates the use of a low cost digital panel meter for the display of temperature on either the Kelvin, Celsius, or Fahrenheit scales. For Kelvin temperature, Pin 9, Pin 4, and Pin 2 are grounded; for Fahrenheit temperature, Pin 4 and Pin 2 are left open ...
