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 50-ohm transmission lines for signal traces.
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 operation. As a general rule, it's recommended to keep the cable length as short as possible (less than 10 inches) to minimize signal degradation and noise pickup.
To handle EMI and RFI, it's recommended to use proper shielding, grounding, and filtering techniques, such as using a metal enclosure, connecting the device to a solid ground plane, and using EMI filters or ferrite beads on the input and output lines.
The recommended power-up sequence for the LMP92064SDX/NOPB is to apply the analog power supply (AVDD) first, followed by the digital power supply (DVDD), and then the input signals. This sequence helps to prevent latch-up and ensures proper device operation.
