Instructions for Using the LM35DM:

1. Power Supply:

   • The LM35DM can operate with a supply voltage ranging from 4V to 30V.
   • Ensure that the power supply is stable and within the specified range to avoid damage to the device.

2. Temperature Measurement:

   • The output voltage of the LM35DM is directly proportional to the temperature in Celsius.
   • For every 1°C increase in temperature, the output voltage increases by 10mV.
   • Example: At 25°C, the output voltage will be approximately 250mV.

3. Quiescent Current:

   • The quiescent current is very low, typically around 70μA at 25°C.
   • This makes the LM35DM suitable for battery-powered applications.

4. Thermal Response Time:

   • The thermal response time is relatively fast, typically between 0.1s and 1s in air.
   • This ensures quick and accurate temperature readings.

5. Operating and Storage Temperature:

   • The operating temperature range is from -55°C to 150°C.
   • The storage temperature range is from -65°C to 150°C.
   • Ensure that the device is not exposed to temperatures outside these ranges to prevent damage.

6. Output Impedance:

   • The output impedance is very low, typically around 0.5Ω at 25°C.
   • This allows the device to drive loads without significant voltage drop.

7. Line and Load Regulation:

   • The line regulation is very good, with a typical value of 0.05mV/V.
   • The load regulation is also excellent, with a typical value of 0.05mV/mA.
   • These characteristics ensure that the output voltage remains stable under varying supply and load conditions.

8. Mounting and Handling:

   • Handle the device with care to avoid mechanical stress or damage.
   • Mount the device in a location where it can accurately sense the ambient temperature without being influenced by heat sources.

9. Calibration:

   • The LM35DM is factory-calibrated and does not require additional calibration for most applications.
   • However, if higher accuracy is required, you can calibrate the device using known temperature points and adjusting the circuit accordingly.

10. Interfacing with Microcontrollers:

    • The output of the LM35DM can be directly connected to an analog-to-digital converter (ADC) input of a microcontroller.
    • Use the ADC to read the output voltage and convert it to temperature using the formula: Temperature (°C) = Output Voltage (mV) / 10.

By following these instructions, you can effectively use the LM35DM for temperature sensing in various applications.
