PCM2903EVM-U: How to use this EVM to convert analog audio input to USB audio output

Part Number: PCM2903EVM-U


Hi,

We are working on a new project and tried to use this EVM to see if we can convert the analog audio input to USB audio output. From the datasheet and the EVM UG, it's not clear how to achieve this. Can you provide some directions? Thank you.

Best Regards,

    Just by looking at the block diagram, it seems as if all you do is connect the board's USB port to your computer, connect a stereo audio source to the board's analog inputs, and run a program like Audacity on your computer to capture the digitized audio.

    Hi Andy,

    Thanks for the response, I have tried what you suggested but got nothing on the computer. In addition, out project would require convert the input analog audio to USB output with USB headphone connected. From the data sheet, it seemed this IC should be able to perform this function but I am not sure. Would this IC support this function? Thank you.

    Best Regards,
