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

S data as follows:

Sample rate (kHz) Approximate ramp rate

8/16/32 125 μs/step

11.025/22.05/44.1 90.7 μs/step

12/24/48 83.3 μs/step
