A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a common ground point for the analog and digital grounds.
Use a reliable communication protocol like SPI or I2C, and ensure proper signal termination and routing. Also, consider using a buffer or repeater for long signal lines.
The device has a thermal pad on the bottom, so ensure good thermal conductivity by using a thermal interface material and a heat sink if necessary. Keep the device away from heat sources and ensure good airflow.
The POR and BOD features are enabled by default. Ensure that the power supply is stable and within the recommended voltage range. You can also use external resistors to adjust the POR and BOD thresholds if needed.
The device has built-in ESD protection, but it's still important to follow proper ESD handling procedures during assembly and testing. Use ESD-safe materials and equipment, and ensure that the device is properly grounded during handling.
