TLV320AIC3120EVM-U: TLV320AIC3120EVM-U : MIC_DET pin functionality

Part Number: TLV320AIC3120EVM-U

Hi expert,

I am at initial stage in understanding the CODEC. Here I need a small clarification on MIC_DET pin which are as follows :

  1. Can you please clarify on the hardware connection and functionality of MICDET as it is provided for headset and also for the MIC1LP.
  2. Please confirm type of headphone need to be connected – TRRS : OMTP / CTIA.
  3. Can I connect earphones which is having built-in mic to headphone jack (J4).
