LM35DH/NOPB datasheet by Texas Instruments

LM35DH/NOPB Frequently Asked Questions (FAQs)

• What is the accuracy of the LM35DH/NOPB?
  The LM35DH/NOPB has an accuracy of ±0.5°C at room temperature (25°C) and ±1°C over the entire operating range of -55°C to 150°C.
• How do I connect the LM35DH/NOPB to a microcontroller?
  The LM35DH/NOPB can be connected to a microcontroller using an analog-to-digital converter (ADC) pin. The output voltage of the LM35DH/NOPB is proportional to the temperature, so the microcontroller can read the voltage and convert it to a temperature value.
• Can I use the LM35DH/NOPB in a humid environment?
  Yes, the LM35DH/NOPB is designed to operate in humid environments. However, it's recommended to take precautions to prevent moisture from entering the package, such as using a conformal coating or potting the device.
• How do I calibrate the LM35DH/NOPB?
  The LM35DH/NOPB does not require calibration. It is a calibrated device that provides an accurate temperature reading out of the box. However, if you need to improve the accuracy, you can perform a one-point calibration by measuring the output voltage at a known temperature and adjusting the reading accordingly.
• What is the self-heating effect of the LM35DH/NOPB?
  The LM35DH/NOPB has a self-heating effect of approximately 0.08°C/mW. This means that the device can heat up by 0.08°C for every milliwatt of power dissipated in the device. This effect is typically negligible in most applications.
