A symmetrical layout with a star-shaped ground connection and a separate analog and digital ground plane is recommended. Keep the analog and digital circuits separated, and use a common ground point for the entire circuit.
Use a metal shield around the TDA2653A, and ensure good grounding and decoupling. Keep the input and output tracks short and away from each other, and use a common mode choke or ferrite bead to filter out high-frequency noise.
The maximum allowed power dissipation for the TDA2653A is 2.5W. Ensure proper heat sinking and thermal management to prevent overheating.
Use an oscilloscope to check the input and output waveforms, and verify the supply voltage and current. Check for proper grounding, decoupling, and layout. Consult the datasheet and application notes for troubleshooting guidelines.
The TDA2653A is rated for operation up to 85°C. For high-temperature applications, consider using a heat sink or thermal management system to prevent overheating. Consult the datasheet for temperature derating information.
