TLV320AIC3256EVM-U 4 channel in - 4 channel out?

Richard Clark1

It looks like the module can do 4 channels out to the DAC and send signal to Line Out and HP out. Problem is, I don't need analog outputs.

What I really want to use the device for, is 2 channels in from Line IN and 2 channels in from Mic IN, to the computer, all at 44khz. Effectively, we want to use the 2 channels from Line IN to subtract from each other and send the result to the computer, which I have working just fine. I route that to one of the two outputs to the computer and all is well. Is it also possible to read one of the analog inputs from Mic IN and route that to the other remaining computer input? I've poked around at everything and can't find it. It just won't let me have more than two analog inputs. Is that correct?

Optimally, I'd like 4 analog inputs and 4 computer inputs. I could live with 3 analog inputs and 2 computer inputs. Can I even do that?

Thanks!

Hello Richard,

Looking into this a little more it may be possible to do this, however you can only commuicate to a single processor at a time. Did you need to do simultaneous communication? or can you do one at a time?

Best regards,

Nate

Nate,

Thanks, but I think we've come to grips with the fact that there are really only two analog inputs on the board. So, we'll make due with two outputs to the computer.

Thanks again!
