Instructions for AD580JH

1. Power Supply:

   • Ensure the supply voltage is within the specified range of 4.5V to 30V to avoid damage and ensure optimal performance.

2. Output Current Limitation:

   • The device can provide up to 10mA output current under short circuit conditions. Avoid exceeding this limit to prevent potential damage.

3. Quiescent Current:

   • At a supply voltage of 30V, the quiescent current is typically around 2mA. This value should be considered in power budget calculations.

4. Operating Temperature:

   • Operate the device within the temperature range of -40°C to +85°C to ensure reliable operation.

5. Initial Accuracy:

   • The initial accuracy at room temperature (25°C) is ±1mV. Calibration may be necessary for applications requiring higher precision.

6. Load and Line Regulation:

   • For minimal changes in output voltage due to load or line variations, ensure that the load regulation (0.5μV/mA) and line regulation (0.2μV/V) are accounted for in your design.

7. Long-Term Stability:

   • The device exhibits long-term stability with drift less than 2μV/hr over 1000 hours at 25°C. Consider this parameter for extended use scenarios.

8. Thermal Drift:

   • The thermal drift is 2μV/°C. Use appropriate thermal management techniques if operating over wide temperature ranges to maintain accuracy.
