Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using vias to connect signals to the ground plane.
To ensure accurate temperature measurement, it's essential to follow proper thermal design practices, such as placing the device in close proximity to the temperature source, using a thermocouple or thermistor with a high accuracy rating, and calibrating the device according to the datasheet instructions.
The maximum cable length for the differential output depends on the specific application and the frequency of the signal. As a general rule, it's recommended to keep the cable length as short as possible to minimize signal degradation and noise pickup. A good starting point is to limit the cable length to 1-2 meters.
To handle EMI and EMC issues, it's essential to follow proper design practices, such as using shielding, grounding, and filtering techniques. Additionally, ensure that the device is placed in a metal enclosure, and use EMI-absorbing materials to minimize radiation.
The recommended power-up sequence for the LMP92064SD/NOPB is to power up the VCC supply first, followed by the AVCC supply. This ensures that the internal voltage regulators are properly initialized and that the device operates correctly.
