LM35AH Frequently Asked Questions (FAQs)

  • The LM35AH has an accuracy of ±0.5°C at room temperature (25°C) and ±1.5°C over the entire operating temperature range of -55°C to 150°C.
  • The LM35AH can be connected to a microcontroller using an analog-to-digital converter (ADC) pin. The output voltage of the LM35AH is proportional to the temperature, so the microcontroller can read the voltage and convert it to a temperature value using a lookup table or formula.
  • Yes, the LM35AH is suitable for use in humid environments. It has a hermetically sealed package that protects the sensor from moisture and contaminants. However, it's still important to follow proper PCB design and assembly practices to ensure the sensor is not exposed to excessive moisture.
  • The LM35AH does not require calibration. It is a calibrated device that provides an accurate temperature reading directly. However, if you need to improve the accuracy of the temperature measurement, you can perform a system-level calibration by comparing the LM35AH output to a known temperature reference.
  • The response time of the LM35AH is approximately 30 seconds in still air. This means that it takes around 30 seconds for the sensor to settle to its final temperature reading after a temperature change.
