A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the device is recommended for optimal thermal performance. This helps to dissipate heat efficiently and reduce thermal resistance.
To ensure accurate temperature measurement, it is essential to calibrate the device, use a high-precision voltage reference, and minimize noise and thermal gradients on the PCB. Additionally, consider using a thermocouple or other temperature reference point for calibration.
The recommended power-up sequence is to apply VCC first, followed by VLOGIC. This ensures that the internal voltage regulator is powered up before the logic circuits, preventing any potential latch-up or damage to the device.
To handle the limited output current capability of the LMT01LPGM, use a buffer amplifier or a voltage follower to increase the output current drive capability. This is particularly important when driving heavy loads or long cables.
To mitigate EMI and RFI, use a shielded enclosure, keep the device away from high-frequency sources, and use a low-pass filter or ferrite bead on the output lines. Additionally, ensure good PCB layout practices, such as separating analog and digital grounds, and using a solid ground plane.
