Can digital microphone PDM output be interfaced with I²S directly?
A PDM output microphone, such as the ADMP421, cannot directly interface to an I2S port. This microphone should be connected to the PDM input on codecs such as the ADAU1361 and ADAU1761. The ADMP441 MEMS microphone has an I2S output that can be connected directly to a processor or codec's I2S port.
