The DA7212 supports 2 Digital mics on MIC1 channel and can support one Analog mic on the MIC2 channel.
The datasheet says that the ADC digital filter is shared for the analog/digital mic channels. So either the analog mic or digital mic can use this ADC digital filter
Can I get the Analog Mic ADC data to the I2S without using the ADC digital filter. If this is possible, then can I add 2 digital microphones on the MIC1 channel( I can do the digital filtering on the Analog mic in my firmware )?
You can use the AMIC and DMIC, however both will effectively go through the ADC filters. If you enable the ADC_FILTER1, which has the voice and music filters both paths (AMIC, DMIC), will be effected by the filters.
