The Great Search: I2S microphone @DigiKey @Adafruit

On previous Great Searches we’ve looked for analog MEMS mics and I2S Quad ADCs but we haven’t yet done I2S MEMS microphones.

These are nifty little all-in-one chips that have a microphone port plus I2S output. All you have to do is send BCLK and LRCLK and 24- or 32-bit data pops out, no configuration or amplification or filtration or digitization or quantization required. You pay a little more but for small builds, they’re easy as pie.

We had a request for an I2S MEMS mic using the ICS-43434 and we thought we’d take a look through the DigiKey and TDK catalogs for some good options!

See the video below and the chosen parts on DigiKey here.
