Texas Instruments recommends a layout with a thermal pad connected to a large copper area on the PCB to dissipate heat efficiently. The copper area should be connected to a ground plane to reduce thermal resistance.
The LM61BIZ/LFT3 does not require calibration, as it is factory-calibrated to provide accurate temperature measurements. However, if high-accuracy measurements are required, users can perform a one-point calibration by measuring the temperature at a known reference point and adjusting the offset accordingly.
The maximum cable length for the LM61BIZ/LFT3's digital output depends on the specific application and the noise environment. As a general guideline, Texas Instruments recommends keeping the cable length below 10 inches (25 cm) to minimize signal degradation and noise susceptibility.
Yes, the LM61BIZ/LFT3 is designed to operate in high-vibration environments. However, users should ensure that the device is properly mounted and secured to the PCB to prevent mechanical stress and damage.
The LM61BIZ/LFT3's POR is an internal reset that occurs during power-up. Users should ensure that the device is powered up slowly (dv/dt < 10 mV/μs) to prevent false triggering of the POR. Additionally, users can add an external capacitor to the VCC pin to filter out power supply noise and reduce the likelihood of POR triggering.
