ADC Control - Address 04h
De-Emphasis Control (Bit 1)
Function:
The standard 50/15 μs digital de-emphasis filter response,
rate of 44.1 kHz when the DeEmph bit is configured as shown in
only in Single-Speed Mode.
Functional Mode (Bits 7:6)
Function:
Selects the required range of sample rates.
ADC Digital Interface Format (Bit 4)
Function:
The required relationship between LRCK, SCLK and SDOUT is defined by the ADC Digital Interface For-
mat bit. The options are detailed in
