Address: 0x001F, Reset: 0x00, Name: ADC0_VOLUME

When SINC_0_EN is set, the volume starts to ramp from −95.625 dB to the value in this register. The volume ramp time is (number of

steps) × 16/fS, where there are 256 steps between 0 dB and −95.625 dB. For example, with fS = 192 kHz, the volume ramps from −95.625 dB

to 0 dB in 21 ms.
