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 thermal pad or heat sink to dissipate heat, and ensure good airflow around the device. Avoid operating the device near its maximum temperature rating for extended periods.
Power up the device in the following sequence: VDD, VDDA, and then VREF. Ensure that VDDA is powered up before VREF, and VREF is powered up before the analog inputs.
Use a suitable output capacitor to filter the output voltage, and ensure the PCB traces can handle the high output current. Consider using a current sense resistor to monitor the output current.
Use a shielded enclosure, keep the device away from antennas and other EMI sources, and use a common-mode choke or ferrite bead to filter the output.
