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 I2S 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
