[FAQ] PCM9211: Recommendation for ADC input connection when ADC is not used

For PCM9211 unused pins, follow the below convention -

- Ground all unused DIGITAL inputs.

- Do not ground unused ANALOG inputs (but you may connect them to a 100nF cap to GND).

No power supply is required for the VCCAD pin & VCCAD should be connected to AGND.

Best regards,
