   • At a reference temperature of 298.2 K (25°C), the device is calibrated to output 298.2 μA.

2. Wide Power Supply Range:

   • The AD590MH/883B operates within a power supply voltage range of 4 V to 30 V.

3. High Impedance Output:

   • The device acts as a high impedance, constant current regulator, which makes it insensitive to voltage drops over long lines. This feature makes it suitable for remote temperature sensing applications.

4. Ease of Use:

   • The AD590MH/883B does not require linearization circuitry, precision voltage amplifiers, resistance measuring circuitry, or cold junction compensation, simplifying its integration into various systems.
   • It is available in various package options, including 2-pin FLATPACK, 4-pin LFCSP, 3-pin TO-52, 8-pin SOIC, and die form, catering to different application needs.

5. Versatile Applications:

   • In addition to temperature measurement, the AD590MH/883B can be used for temperature compensation or correction of discrete components, biasing proportional to absolute temperature, flow rate measurement, level detection of fluids, and anemometry.

6. Laser Trimming for Accuracy:

   • State-of-the-art laser trimming at the wafer level, combined with extensive final testing, ensures high accuracy and interchangeability of AD590MH/883B units.

7. Robustness and Reliability:

   • The AD590MH/883B offers good electrical durability, withstanding up to 44 V of forward voltage and 20 V of reverse voltage. This makes it resilient to power irregularities or pin reversals.

8. Low Power Consumption:

   • With a power requirement of only 1.5 mW at 5 V and 25°C, the AD590MH/883B is energy-efficient and suitable for applications where power consumption is a concern.

In summary, the AD590MH/883B is a versatile, accurate, and easy-to-use temperature sensor that offers a wide range of applications and packaging options. Its precision, combined with low power consumption and robustness, makes it an attractive choice for various temperature measurement needs.
