LM35DZ/LFT1 Frequently Asked Questions (FAQs)

• What is the accuracy of the LM35DZ/LFT1 over the entire operating temperature range?
  The LM35DZ/LFT1 has an accuracy of ±0.5°C at room temperature (25°C) and ±1°C over the entire operating temperature range of -55°C to 150°C.
• How do I connect the LM35DZ/LFT1 to a microcontroller?
  The LM35DZ/LFT1 can be connected to a microcontroller using a simple analog-to-digital converter (ADC) interface. The output voltage of the LM35DZ/LFT1 is proportional to the temperature, so the microcontroller can read the voltage using an ADC and convert it to a temperature reading.
• Can I use the LM35DZ/LFT1 in a humid or high-moisture environment?
  The LM35DZ/LFT1 is not recommended for use in humid or high-moisture environments as it is not hermetically sealed and may be susceptible to moisture ingress. However, it can be used in environments with moderate humidity levels with proper packaging and sealing.
• What is the self-heating effect of the LM35DZ/LFT1?
  The self-heating effect of the LM35DZ/LFT1 is typically around 0.1°C to 0.2°C, which means that the device can heat up by this amount due to its own power consumption. This effect is usually negligible in most applications.
• Can I use the LM35DZ/LFT1 for high-accuracy temperature measurement applications?
  While the LM35DZ/LFT1 is a high-accuracy temperature sensor, it may not be suitable for extremely high-accuracy applications (e.g., ±0.1°C or better). For such applications, more precise temperature sensors like platinum RTDs or thermistors may be required.
