I have a couple of questions regarding ADAU1979.
1) what is the value of the Vref used by the chip
2) when the chip is operating in slave mode (LRCLK pin as clock source) the MCLKIN pin should be left not connected or pulled to GND / VCC
3) how can I configure a sampling rate of 8kHz (is this done by setting the FS field from SAI_CTRL0 register to 00 and the frequency provided by LRCLK ?)
Thank you for the help!
