Texas Instruments recommends a 4-layer PCB with a solid ground plane and a thermal relief pattern around the device to minimize thermal gradients and ensure accurate temperature measurements.
The LM45BIM3 does not require calibration, as it is a calibrated device. However, to achieve high-accuracy temperature measurements, it is recommended to use a precision voltage reference and to ensure that the device is operated within its specified temperature range.
The maximum cable length for the LM45BIM3's output signal depends on the specific application and the noise environment. As a general rule, it is recommended to keep the cable length as short as possible (less than 10 inches) to minimize noise pickup and ensure accurate temperature measurements.
Yes, the LM45BIM3 is designed to operate in high-vibration environments. However, it is recommended to ensure that the device is properly mounted and secured to the PCB to prevent mechanical stress and ensure accurate temperature measurements.
To protect the LM45BIM3 from EMI, it is recommended to use a shielded cable for the output signal, to keep the device away from high-current carrying wires, and to use a ferrite bead or a common-mode choke to filter out high-frequency noise.
