Figure 12. Input channel switching sequence example
Note:
(1) The output signal is attenuated by −∞ within 1024 LRCK cycles (1024/fs).
(2) When changing channels, the input channel should be changed during (2). The period of (2) should be around
200ms because there is some DC difference between the channels.
