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



      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?
