Part Number: PCM9211

What is recommended ADC input connection when ADC is not used?

 

Best regards,

Ravi

  • 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,
    Ravi
