TMP144YFFR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a thermal relief pattern on the top layer to minimize thermal resistance. A thermal pad on the bottom of the device should be connected to the ground plane.
  • The TMP144 has a high output impedance, so it's essential to use a buffer amplifier or an op-amp with a high input impedance to prevent signal degradation. Additionally, keep the output trace as short as possible and use a low-capacitance cable to minimize signal attenuation.
  • Texas Instruments recommends a 2-point calibration procedure: calibrate the device at 0°C and 100°C using a precision temperature reference. This ensures accurate temperature readings across the entire operating range.
  • In high-temperature applications, ensure the TMP144 is mounted on a thermally conductive material, such as a metal heat sink or a thermally enhanced PCB. Also, consider using a thermocouple or a thermistor in parallel with the TMP144 to provide redundancy and improve accuracy.
  • The maximum cable length depends on the specific application and the signal integrity requirements. As a general guideline, keep the output cable length below 10 inches (25 cm) to minimize signal attenuation and noise pickup. Use a shielded cable and a twisted pair configuration to reduce electromagnetic interference.
