BT-MSPAUDSOURCE: How to connect Microphone

BT-MSPAUDSOURCE: How to connect Microphone

Part Number: BT-MSPAUDSOURCE

Hi,

Good day.

Posting this question as a related inquiry. I just receive additional information from the customer.

when I connect audio source to the mic pins, it is working. Now, I used an amplifier after mic and connected it.. It started working. after sometime one channel stopped working. is it because of amplifier that I used? one more thing, can it directly pick from mic, which is not happening in our case.

Can you please help? Thank you.


Regards,

Cedrick

    Hi Cedrick,

    The BT-MSPAUDSOURCE is designed to use the 3.5mm audio jack on the board as the audio source. If the customer tries to connect a microphone directly to the TLV320ADC3101 in any other way, they will have to make hardware and software changes on the BT-MSPAUDSOURCE board.

    Do you know what pins the customer is connecting to?

    Thanks,
    Jacob

    Hi Cedrick,

    I am not sure of the exact hardware and software changes needed on the BT-MSPAUDSOURCE board. A good starting place for the customer is the schematic on the BT-MSPAUDSOURCE reference design page. If the customer uses the 3.5mm audio jack, does the board work as expected?

    If the customer has a specific question on the TLV320ADC3101, I can move this thread to that group. 

    Thanks,
    Jacob
