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)
8/16/32
Approximate Ramp Rate
125 us/step
11.025/22.05/44.1
12/24/48
90.7 us/step
83.3 us/step
