Instructions for Using the LM35DZ:

  1. Supply Voltage:

    • The LM35DZ can operate with a supply voltage ranging from 4V to 30V. Ensure the supply voltage is within this range to avoid damage to the device.
  2. Output Voltage:

    • The output voltage of the LM35DZ is directly proportional to the temperature in Celsius. The typical output is 10mV/掳C. For example, at 25掳C, the output voltage will be 250mV.
  3. Quiescent Current:

    • The quiescent current is typically 60渭A at 25掳C. This low current draw makes the LM35DZ suitable for battery-powered applications.
  4. Temperature Sensitivity:

    • The temperature sensitivity is 10mV/掳C. This means that for every degree Celsius increase in temperature, the output voltage increases by 10mV.
  5. Temperature Range:

    • The LM35DZ is designed to operate over a wide temperature range from -55掳C to +150掳C. It is suitable for both industrial and consumer applications.
  6. Output Impedance:

    • The output impedance is very low, typically 0.1惟 at 25掳C. This ensures that the output voltage remains stable even when connected to a load.
  7. Thermal Resistance:

    • The thermal resistance (R胃JA) of the TO-92 package is 200掳C/W. This value is important for heat dissipation considerations, especially in high-temperature environments.
  8. Circuit Connection:

    • Connect the positive terminal of the power supply to the VCC pin, the negative terminal to the GND pin, and the output pin to your measurement circuit.
    • A bypass capacitor (e.g., 0.1渭F) between VCC and GND is recommended to filter out any noise and ensure stable operation.
  9. Handling Precautions:

    • Handle the LM35DZ with care to avoid static discharge, which can damage the device.
    • Ensure proper heat sinking if the device is used in high-temperature environments or under high power conditions.

By following these guidelines, you can effectively use the LM35DZ temperature sensor in your projects.
