RE: ADAU1761 DC gain in the digital mic path

maheshmuni

Hi Tyler,

Thanks for the response.

Adding to the above, ADAU1761 has two omnidirectional MEMS microphones, which are analog devices part number ADMP421 ICs (U3 and U4 on the board). About this microphones, how many data bits the ADMP421 is giving and…
