VOLUME CONFIGURATION REGISTER (0x0E)
Bits Volume slew rate (used to control volume change and MUTE ramp rates). These bits control the
D2–D0: number of steps in a volume ramp. Volume steps occur at a rate that depends on the sample rate of
the I
2
S data as follows:
Sample rate (kHz) Approximate ramp rate
8/16/32 125 ms/step
11.025/22.05/44.1 90.7 ms/step
12/24/48 83.3 ms/step
