Hi team,

customer is designing the ADC3100 with analog mic application.
the mic will from the 3.5mm connector. the end-user can but the 3.5mm mic as the input. for this case, what the recommended mic bias setting for ADC3101?

    Hi, Scott,

    Sorry for the delay. Can you please provide more information about this question?. Is it a concern with the mechanical connection between the mic and the ADC?. For a typical 3.5mm plug MIC connection, a TS connector is used (Tip, Sleeve), where the tip is tied to the mic and Sleeve to GND. From the ADC point of view, the tip should be tied to the mic input and micbias resistor.
