Troubleshooting ADC performance issues requires systematic analysis: 1) Verify power supplies - measure with oscilloscope for noise and ripple; 2) Check reference voltage - reference noise directly affects ADC performance; 3) Validate clock quality - use spectrum analyzer to check jitter and phase noise; 4) Review PCB layout - ensure proper grounding and decoupling; 5) Test with known input - short inputs to verify offset, apply DC for noise measurement; 6) Check digital interface - verify timing with logic analyzer; 7) Review configuration registers - ensure correct settings for your application. Common issues include: inadequate anti-aliasing filters causing aliasing, ground loops introducing noise, insufficient reference decoupling, and clock jitter degrading high-frequency performance. ADI's evaluation software includes diagnostic tools to help identify issues. Contact our FAE team for assistance with complex troubleshooting scenarios.

Start with power and reference checks, then verify clock quality and PCB layout; use evaluation software diagnostics.
