6.10.1 DAC1 De-Emphasis Control
This bit enables the digital filter to apply the standard 15μs/50μs digital de-emphasis filter response for a
sample rate (Fs) of 44.1 kHz. De-emphasis is available only in Single-Speed Mode.

6.10.2 DAC1 Single Volume Control
The individual channel volume levels are independently controlled by their respective Volume Control reg-
isters when this function is disabled. When enabled, the volume on DAC1 channels is determined by the
DAC1A Volume Control register and the DAC1B Volume Control register is ignored.

6.10.3 DAC1 Soft Ramp Control
Soft Ramp allows level changes, both muting and attenuation, to be implemented by incrementally ramp-
ing, in 1/8 dB steps, from the current level to the new level at a rate of 1 dB per 8 left/right clock periods.
