0010=375us

0011=750us

0100=1.5ms

0101=3ms

0110=6ms

0111=12ms

1000=24ms

1001=48ms

1010=96ms

1011 to 1111=192ms

7:4

LIMDCY

0011

Limiter Decay time (per 6dB gain

change) for 44.1kHz sampling. Note

that these will scale with sample rate:

0000=750us

0001=1.5ms

0010=3ms

0011=6ms

0100=12ms

0101=24ms

0110=48ms

0111=96ms

LIMEN

Enable the DAC digital limiter:

0=disabled

1=enabled

3:0

LIMBOOST

0000

Limiter volume boost (can be used as a

stand alone volume boost when

LIMEN=0):

0000=0dB

0001=+1dB

0010=+2dB

… (1dB steps)

1011=+11dB

1100=+12dB

1101 to 1111=reserved

LIMLVL

000

Programmable signal threshold level

(determines level at which the limiter

starts to operate)

000=-1dB

001=-2dB

010=-3dB

011=-4dB

100=-5dB

101 to 111=-6dB
