Minimize Ground Loops: Avoid creating ground loops, which can induce noise. Ensure that all ground connections are made at a single point to avoid interference. 7. Consider Using a Power Management ICIf you're facing complex power management needs, consider integrating a power management IC (PMIC) that can regulate voltage and current and provide stable and clean power for the ADS1251U.
These ICs can offer additional features such as voltage sequencing or overcurrent protection to ensure the power supply remains within specifications.
Final Checks
Once all the above steps have been followed, perform a final check to ensure that the ADS1251U is operating correctly. Verify that the output readings are accurate and that no issues with noise or instability are present. If the problem persists, review the entire power supply circuit and consider consulting the ADS1251U datasheet for additional recommendations and specifications.
By carefully addressing the power supply issues with these steps, you can ensure the ADS1251U operates reliably and provides accurate results for your application.
