Hi,

 

at present i am working with a ADAV801-based CODEC-board, which works fine and is easy to handle by setting the approriate registers.

 

In addition now  i want to use the ALC-function of the ADAV801 because the ADC Input level is not well defined .Assuming the concerned registers are the ALC Control Register 1,2,3.

 

The ADC input signal Vin actually is already saturated, but there is no ALC action noticeable at any settings of the ALC control registers.What may be wrong?

 

Kind regards

Christian
