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 )?
