Can an I2S microphone be used for a microphone input instead of the PDM inputs? Are there any advantages / disadvantages?
Hello sdn,
I hope this attached document will help you to understand more about I2S and PDM mic interfaces.
(1) Difference between PDM and i2s Digital Microphones? - Q&A - Audio - EngineerZone (analog.com)
In ADAU1467, PDM microphone inputs are automatically routed through decimation filters are and then available for use at the DSP core, the ASRCs, and the serial output ports. Please refer the PDM interface topic at the datasheet as well to know how to connect it with the processor.
Please do reply if you have further queries.
