Design Notes

Provide a clean analog supply (AVDD) and digital supply (DVDD) with proper decoupling. Use 10uF and 0.1uF capacitors close to the AVDD and DVDD pins. The analog supply should be isolated from digital noise to maintain the ADC's high resolution.

Place the reference input bypass capacitor (0.1uF) close to the REF+ and REF- pins. Use a star-ground topology to separate analog and digital grounds. Keep the SPI lines away from analog input traces to prevent noise coupling.

Ensure the reference voltage is stable and low-noise. Use a precision reference like the ADR4520. Avoid exceeding the absolute maximum ratings on the analog inputs. The SPI interface should be operated at appropriate logic levels to prevent latch-up.
