Is it possible to directly interface a MEMS ADMP541 microphone over I2S with any Microcontroller?
I find this MEMS microphone : ADMP504
As you can see this microphone has a analog output so you need to connect it to a dedicated codec microphone input ADAU1761. The codec is connected to a controller via I2C. If your microphone has an integrated codec than you can connect it directly to the arduino without a problem.
