If issues continue, consider revising the PCB design to ensure optimal grounding. You may need to add additional vias or widen the ground traces to improve grounding.Conclusion
When troubleshooting power supply issues with the ADS1256IDBR, it's crucial to address common problems such as low voltage, noise, overvoltage, insufficient current, and improper grounding. By systematically checking each aspect of the power supply, from voltage and current levels to grounding, you can identify the root cause of the issue and implement a solution. Always ensure that the power supply is within the required specifications, use proper filtering and decoupling methods, and verify the integrity of your grounding system to ensure reliable operation of the ADS1256.
