We want to use an ADAU1772 and four omnidirectional MEMS micropuhones
to create a breamforming application.
In ADAU1772 datasheet figure67, AIN2 and AIN3 are configured as a stereo line-in.
My question is, are those four analog input (AIN0-AIN3) completely the same?
As shown below, can AIN2 and AIN3 be configured as microphone input with micbias?
