Design Notes

Decouple the VDD and VIO supplies with 0.1uF and 10uF capacitors placed close to the pins. The reference input should be bypassed with a 10uF capacitor to ensure stability. Use a low-noise LDO for the analog supply to minimize noise coupling into the ADC.

Keep the analog input trace short and shielded to reduce noise pickup. Use a ground plane under the ADC and avoid routing digital signals near the analog input. The exposed pad should be soldered to the ground plane for thermal and electrical performance.

Ensure the SCLK frequency does not exceed the maximum specified in the datasheet to avoid conversion errors. The CNV pin must be held low during conversion. Also, verify that the reference voltage is within the specified range to maintain accuracy.
