DAC Control - Address 03h
6.3.1
DAC Functional Mode (Bits 7:6)
Function:
Selects the required range of input sample rates.
6.3.2
DAC Digital Interface Format (Bits 5:4)
Function:
The required relationship between LRCK, SCLK and SDIN for the DAC is defined by the DAC Digital
Interface Format and the options are detailed in Table 6 and Figures 7-9.
6.3.3
Mute DAC (Bit 2)
Function:
The DAC outputs will mute and the MUTEC pin will become active when this bit is set. Though this
bit is active high, it should be noted that the MUTEC pin is active low. The common mode voltage on
the outputs will be retained when this bit is set. The muting function is effected, similar to attenuation
changes, by the DACSoft and DACZero bits in the DAC Control 2 register.
6.3.4
De-Emphasis Control (Bit 1)
Function:
The standard 50/15
μ
s digital de-emphasis filter response, Figure 20, may be implemented for a sam-
ple rate of 44.1 kHz when the DeEmph bit is configured as shown in Table 7 below. NOTE: De-em-
phasis is available only in Single-Speed Mode.
