I have a design where I use ADAU1702. I have two audio input sources to my system that I want to be able to select between:
Source (1): I2S stereo digital channel from a Bluetooth module
Source (2): Analog stereo channel input from a line in jack.
I wonder if someone can help me (show a SigmaStudio schematic) how I can implement the following function:
Select analog stereo input if I/O#X=high
Select I2S digital stereo input if I/O#X=low
I will do the same audio processing for the both signals so I just need an I/O-pin-controlled stereo mux.
Is pin "2" in the input block the "left channel part" of I2S stereo input (SDATA_IN0) and pin "3" the "right channel part"?
Thanks in advance and have a nice weekend!
