The AD590 is particularly useful in remote sensing applications.
- The AD590 is a calibrated, 2-terminal temperature sensor
- State-of-the-art laser trimming at the wafer level in
AD590 units are easily interchangeable.
- Superior interface rejection occurs, because the output is a
features make the AD590 easy to apply as a remote sensor.
- The high output impedance (>10 MΩ) provides excellent
a 1 µA maximum current change, or 1°C equivalent error.
- The AD590 is electrically durable: it withstands a forward
voltage of up to 44 V and a reverse voltage of 20 V.

However, the absolute errors specified apply to only the rated performance temperature range. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 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. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
