TMP141AIDGKR Frequently Asked Questions (FAQs)

  • The TMP141AIDGKR has an accuracy of ±1°C from -20°C to 70°C and ±2°C from -40°C to 125°C. This is specified in the datasheet, but engineers often ask for clarification on the accuracy over the entire operating range.
  • When the TMP141AIDGKR is not connected to a microcontroller or ADC, its output voltage can float. To prevent this, connect a 10kΩ pull-down resistor between the output pin and GND to ensure a stable output voltage.
  • To minimize thermal gradients and noise, use a 4-layer PCB with a solid ground plane, keep the sensor away from heat sources, and use a short, direct trace from the sensor to the ADC or microcontroller. Avoid routing digital signals near the sensor's output trace.
  • Yes, the TMP141AIDGKR is rated for operation up to 125°C, making it suitable for high-temperature environments. However, ensure that the device is properly soldered and the PCB is designed to withstand the high temperatures.
  • The TMP141AIDGKR does not require calibration. It is a calibrated device with a built-in temperature sensor and analog-to-digital converter. Simply connect it to a microcontroller or ADC and read the output voltage to obtain the temperature measurement.
