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 analog and digital grounds.
Use a reliable communication protocol like UART, SPI, or I2C, and ensure proper signal termination, signal integrity, and noise reduction techniques are implemented.
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.
Ensure that the power supply is stable and within the recommended voltage range. Use a power-on reset circuit to ensure the device is properly reset during power-up.
Use ESD protection devices like TVS diodes or ESD arrays on the I/O lines, and ensure that the PCB design includes ESD protection features like guard rings and ESD-safe layout practices.
