Part Number: PCM1864


Hello,

We would like to connect AT-9904, audio technica mic. I think datasheet figure 64 can be used but not sure. Would you review if my idea is correct?

Best regards,

    Hi Watanabe-san,
    Looking at the audio-technica mic (thanks for sharing the link), my understanding is that it's similar to interfacing w. analog microphone. So you should be able to use this w PCM186x family of devices. Depending on how many microphones you plan to use in the given application, you will have to choose appropriate device depending on channel count.

    You will also have pin-selectable/programmable gain w. PCM186x device. Hope this clarifies your question.

    Best regards,
    Ravi
