Texas Instruments provides a recommended PCB layout in the application note SLUAAC4, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure optimal performance.
To ensure accurate temperature measurement, it's essential to follow proper calibration procedures, use a high-accuracy voltage reference, and minimize noise and thermal gradients on the PCB. Additionally, the LM96511 has a built-in calibration feature that can be used to compensate for any offset errors.
The maximum cable length for the remote temperature sensing feature depends on the cable type, noise environment, and desired accuracy. As a general guideline, Texas Instruments recommends keeping the cable length below 10 meters to ensure reliable operation. However, with proper shielding and noise filtering, longer cable lengths may be possible.
While the LM96511 is specified for 3.3V or 5V operation, it can operate with a supply voltage as low as 2.7V or as high as 5.5V. However, the device's accuracy and performance may be affected at these extremes. It's recommended to consult with Texas Instruments or perform thorough testing to ensure the device meets the required specifications.
The LM96511's POR and BOR features are designed to ensure the device powers up correctly and recovers from brown-out conditions. To handle these features, it's essential to follow proper power-up sequencing, ensure a stable voltage supply, and add external circuitry to debounce the reset signal if necessary.
