DAC37J84: qmc_gain setteing at "dB"

Part Number:DAC37J84

Hi,

DAC37J84 : Let me question each qmc_gain setting of "Resister Name Config12 ～15".

1) Please tell me the gain correction value (dB) of each when set to "0", "1.0000", "1.9990".

2) As a set value, we consider it to be +3dB when 0x400 (above Range 1.0000).
   Is this the correct answer?

I thought that it was +3dB when set value 0x7FF (above Range 1.9990)
With this setting, we saw the behavior that gain saturation occurred in the DAC.

best regards
