    Analog CoProcessor / Electret Microphone / Scan_ADC: where to connect VAGND?

    user_246598725

      Hi,

      I want to connect a electret microphone, using the Scan_ADC component of the Analog CoProcessor.

         

      I wonder where to connect the VAGND input signal of the Scan_ADC component when filtering on channel 0 is used? The VREF component seems to only support VDDA. Do I have to make an external connection to GND by a dedicated pin?

      Regards,

      Ralf
