ALCMIN

000

Set minimum gain of PGA when using ALC:

000=-12dB

001=-6dB

010=0dB

011=+6dB

100=+12dB

101=+18dB

110=+24dB

111=+30dB

Input Limiter /

Automatic Level

Control (ALC)

ALCZC

ALC zero cross detection.

0 = disabled (recommended)

1 = enabled

It is recommended that zero cross is not used in

conjunction with the ALC or Limiter functions

ALCHLD

000

ALC hold time before gain is increased.

0000 = 0ms

0001 = 2.67ms

0010 = 5.33ms

… (time doubles with every step)

1111 = 43.691s

ALCLVL

1011

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

ALCMODE

Determines the ALC mode of operation:

0=ALC mode

1=Limiter mode.
