  • About ADMP504

    Hi,

    Right now I need to design an endfire array system (in the 1140 app note), based on two ADMP504.I recently saw a video on youtubevidio,eval board designed buy Jared Lewis,that board just what I need ! So how can I get the eval board or some information…

  • Using ADAU1761 for microphone beamforming

    We used an ADAU1761 to create a simple microphone beamforming application, with two omnidirectional ADMP504 MEMS microphones mounted in an endfire configuration.

    Using the attached Excel sheet to perform the calculations, we calculated that a total of…

  • Using ADAU1772 for microphone beamforming

    We used an ADAU1772 to create a simple microphone beamforming application, with two omnidirectional ADMP504 MEMS microphones mounted in an endfire configuration.

    While the ADAU1772 has no delay cells in its library, you can still create delay by using…
