Dear expert,
I have concern on connecting 1uF capacitor on microphone circuit as TLV320ADC3001 datasheet describes as below picture.
Is it required for proper operation? I guess it affect very much on microhpone signal at high frequency.
Can I remove the capacitor from the circuit?
Hi, Kenneth,
It is not necessary to place the capacitor for proper operation. It actually depends of the microphone and its behavior. You may see the minimal connection on the next picture:
Several codecs or adcs have an optional pin for mic detection. It is not necessary to connect it if the mic detection is not needed.
I hope this helps you. Please let me know if you still have questions or comments.
Best regards,
Luis Fernando Rodríguez S.
