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 ferrite bead or inductor to filter the power supply.
Use a thermally conductive material for the PCB, ensure good airflow, and consider using a heat sink or thermal interface material for high-power applications. Also, follow the recommended operating conditions and derating guidelines.
The device's high current consumption requires a power supply with a low output impedance and high current capability. Ensure the power supply can handle the peak current requirements, and consider using a bulk capacitor to filter the output.
Check the input voltage, output voltage, and current consumption. Verify the voltage regulator's enable pin is properly connected and the output capacitor is correctly sized. Use an oscilloscope to monitor the output voltage and look for signs of oscillation or instability.
Use a shielded enclosure, keep the device away from antennas and other EMI sources, and ensure proper grounding and decoupling. Follow good PCB layout practices, such as using a solid ground plane and minimizing trace lengths.
