Having a 384 kHz DAC is not going to help you getting 8 analog channels.
Unless you want to do the demultiplexing in the analog domain, which
will require quite complicated and expensive analog hardware. And that's
assuming that the DAC has indeed an analog bandwidth of 192 kHz, which
it very probably doesn't have.
