Hi,

I'd like to have 2 more analog MIC inputs so is there any other way to add them than to have one more ADAU1787..?

Regards, Osmo

Hi Osmo,

The ADAU1787 supports up to 4 analog inputs, 8 digital microphone channels, and has two serial audio ports capable of TDM16. If you need analog microphones beyond that, you would need to add an additional ADAU1787, or pair it with an external ADC.
