Design Notes
Decouple the AVCC and DVCC pins with 10 µF and 0.1 µF capacitors placed as close to the pins as possible. Use separate analog and digital ground planes to minimize noise coupling. The AVCC supply should be clean and low-noise, as it directly affects ADC performance. A ferrite bead can be used to isolate the analog supply from digital switching noise.
For optimal performance, route analog input traces away from digital traces and keep them short. Use a solid ground plane under the ADC to reduce noise. The REFOUT pin should be bypassed with a 10 µF capacitor to ground to stabilize the internal reference. If using an external reference, connect it to REFIN with a low-impedance source and bypass with 0.1 µF.
Ensure the input voltage does not exceed the absolute maximum ratings, even though the device has clamp protection. The analog input range is set by the RANGE pin; verify it is configured correctly for your application. Do not leave unused analog inputs floating; tie them to AGND or a known potential. Also, ensure the digital interface voltage (DVCC) is compatible with your host controller's logic levels.
