LM34DH datasheet by Texas Instruments

LM34DH Frequently Asked Questions (FAQs)

• What is the accuracy of the LM34DH over the entire operating temperature range?
  The LM34DH has an accuracy of ±1°C from -20°C to 100°C, and ±2°C from -50°C to -20°C and 100°C to 150°C.
• How do I connect the LM34DH to a microcontroller?
  The LM34DH can be connected to a microcontroller using an analog-to-digital converter (ADC) to read the output voltage, which is directly proportional to the temperature. A voltage reference is required to ensure accurate readings.
• What is the output impedance of the LM34DH?
  The output impedance of the LM34DH is typically around 10 kΩ, which means it can drive a load of up to 10 mA without significant voltage drop.
• Can I use the LM34DH in a high-vibration environment?
  Yes, the LM34DH is designed to operate in high-vibration environments, but it's recommended to follow proper PCB layout and mounting guidelines to ensure reliable operation.
• How do I calibrate the LM34DH?
  The LM34DH does not require calibration, as it is factory-calibrated to provide accurate temperature readings. However, it's recommended to perform a system-level calibration to account for any system-specific errors.
