Texas Instruments recommends a layout with a small thermal pad connected to the GND pin, and a minimal number of thermal vias to minimize thermal resistance. A detailed layout guide is available in the application note SLUA271.
The LM62CIM3X/NOPB has a built-in calibration mechanism. However, for high-accuracy applications, users can perform a two-point calibration by measuring the output voltage at two known temperatures (e.g., 0°C and 100°C) and adjusting the offset and gain accordingly.
The maximum cable length depends on the cable capacitance and the desired accuracy. As a general rule, Texas Instruments recommends keeping the cable length below 10 meters to minimize signal attenuation and noise pickup.
Yes, the LM62CIM3X/NOPB is designed to operate in high-vibration environments. However, it's essential to ensure that the device is properly mounted and secured to prevent mechanical stress, which can affect its accuracy and reliability.
To minimize EMI, use a shielded cable, keep the sensor away from high-frequency sources, and ensure good grounding practices. Additionally, consider using a low-pass filter or a ferrite bead to filter out high-frequency noise.
