Please forgive me if this has already been answered elsewhere. I did a quick search and did not see this issue addressed.


I have a customer that would like to use the ADAU1452 in an industrial application.  Their end customers input frequencies range as high as 100 KHz and most designs have multiple input channels.


Can I sample multiple input channels simultaneously?  If not, can I easily cycle thru the inputs and sample sequentially?  If I can sample either simultaneously or sequentially; what is the maximum sample rate per channel?  Is it 192k/ n (N= total number of channels sampled?)
