Instructions for Use:

1. Supply Voltage Connection:

   • Connect the supply voltage (Vcc) between 4V and 30V to pin 3 of the LM35D.

2. Ground Connection:

   • Ensure a solid ground connection to pin 2.

3. Output Measurement:

   • Measure the output voltage at pin 1 relative to ground. The output is calibrated to provide 10mV per degree Celsius.

4. Temperature Sensing:

   • Place the sensor part of the IC in direct contact with or close to the temperature source you wish to measure.

5. Accuracy Considerations:

   • For best accuracy, use the sensor at temperatures around +25°C. Accuracy can vary slightly over the full temperature range.

6. Noise Reduction:

   • If necessary, place a capacitor (e.g., 0.1μF) between the output and ground to reduce noise.

7. Thermal Lag:

   • Be aware that there is a thermal response time of approximately 250ms for step changes in temperature.

8. Package Handling:

   • Handle the device carefully as it is sensitive to electrostatic discharge (ESD).

These guidelines ensure optimal performance of the LM35D temperature sensor in various applications.
