During mono audio capture over PDM, we observed a current draw of about 1.5 mA.

Our setup:

• Board: nRF5340 DK
  
• SDK: NCS v2.6.2
  
• Microphone: MMICT5837-00-012
  
• Interface: PDM
  

During mono audio capture over PDM, we observed a current draw of about 1.5 mA.
My questions are:

• Is there any way to reduce this current consumption further?
  
• How much current does the PDM peripheral itself typically draw in mono mode on the nRF5340 (excluding microphone current)?

Hi Deep,

I am checking this internally with the team and will get back to you.

In the meantime, could you upgrade to a more newer version of the SDK and see if anything improves?

Hi,

I can see that you are already being assisted by my colleague, for the same query in another ticket.

I would suggest you to kindly continue your conversation there as this will help reduce confusions.
