  • FAQ: Can a digital microphone's PDM output be directly connected to an I2S input?

    carol.nelson
    carol.nelson

    A PDM output microphone, such as the ADMP421 or ADMP521, cannot directly interface to an I2S port. Theses microphones should be connected to the PDM input on codecs such as the ADAU1361 and ADAU1761. The ADMP441 MEMS microphone has an I2S output that…

    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…

    Hi, So can you please describe to me differences of ADMP421 −26 dBFS   vs ADMP621  −46 dBFS ?

    1 Which mic I have to use in listening from 1-3 m device? Which device more sensitive?

    2 can I raise internal mic gain?
