Texas Instruments recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a thermal isolation zone around the TMP006 to minimize thermal gradients. See the TMP006 application note (SLUA623) for more details.
The TMP006 does not require calibration, as it is a digital temperature sensor with an internal calibration. However, you can perform a system-level calibration by measuring the temperature of a known reference point and adjusting the sensor's output accordingly.
The maximum cable length for the TMP006's digital output is not explicitly stated in the datasheet, but it is generally recommended to keep the cable length as short as possible (less than 10 cm) to minimize signal degradation and noise.
Yes, the TMP006 is designed to operate in harsh environments, including high-vibration and high-shock conditions. However, it's essential to ensure that the sensor is properly mounted and secured to the PCB to prevent mechanical stress and damage.
The TMP006 has a built-in POR and BOR circuitry that resets the device in case of power-on or brown-out conditions. You can use an external capacitor to filter the power supply and prevent false resets. See the TMP006 datasheet for more information on POR and BOR timing.
