Instructions for Use:

1. Supply Voltage:

   • The LM35CAZ/NOPB can operate with a supply voltage ranging from 4V to 30V. Ensure that the power supply is stable and within this range.

2. Output Voltage:

   • The output voltage is directly proportional to the temperature in Celsius. At 100掳C, the output voltage is 1.000V. The temperature coefficient is 10mV/掳C, meaning the output voltage increases by 10mV for each degree Celsius increase in temperature.

3. Quiescent Current:

   • The quiescent current is typically 60渭A. This low current draw makes the LM35 suitable for battery-powered applications.

4. Output Impedance:

   • The output impedance is very low, typically 0.1惟 at 25掳C, ensuring minimal voltage drop across the load.

5. Operating Temperature Range:

   • The sensor can operate over a wide temperature range from -55掳C to 150掳C. Ensure that the application environment does not exceed these limits.

6. Storage Temperature Range:

   • The device can be stored in temperatures ranging from -65掳C to 150掳C. However, it should be brought to operating temperature before use.

7. Thermal Resistance:

   • The thermal resistance from the junction to the ambient air is 180掳C/W. This value helps in calculating the temperature rise due to self-heating when the device is dissipating power.

8. Mounting and Handling:

   • Handle the device with care to avoid mechanical stress. Ensure proper mounting to maintain accuracy and reliability.

9. Circuit Design:

   • Connect the V_CC pin to the positive supply and the ground pin to the negative supply. The output pin provides the temperature-dependent voltage. Use appropriate decoupling capacitors to filter out noise.

10. Calibration:

    • For high-precision applications, calibrate the sensor using known temperature points to account for any manufacturing variations.
