ALCHLD

[3:0]

0000

(0ms)

ALC hold time before gain is

increased.

0000 = 0ms

0001 = 2.67ms

0010 = 5.33ms

… (time doubles with every step)

1111 = 43.691s

ALCLVL

[3:0]

1011

(-12dB)

ALC target – sets signal level at ADC

input

0000 = -28.5dB FS

0001 = -27.0dB FS

… (1.5dB steps)

1110 = -7.5dB FS

1111 = -6dB FS
