MINIMUM AND MAXIMUM GAIN

The ALCMIN and ALCMAX register bits set the minimum/maximum gain value that the PGA can be

set to whilst under the control of the ALC. This has no effect on the PGA when ALC is not enabled.

Set minimum gain of PGA

Table 17 ALC Max/Min Gain

In normal mode, ALCMAX sets the maximum boost which can be applied to the signal. In limiter

mode, ALCMAX will normally have no effect (assuming the starting gain value is less than the

maximum gain specified by ALCMAX) because the maximum gain is set at the starting gain level.

ALCMIN sets the minimum gain value which can be applied to the signal.
