6.3.3
De-Emphasis Control (Bit 1)
Function:
The standard 50/15 s digital de-emphasis filter response, Figure 17, may be implemented for a sample
rate of 44.1 kHz when the DeEmph bit is configured as shownin Table 8. NOTE: De-emphasis is available
only in Single-Speed Mode.

ADC Control - Address 04h
6.4.1
Functional Mode (Bits 7:6)
Function:
Selects the required range of sample rates.
6.4.2
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 Table 10 and may be seen in Figure 5 and Figure 6.
