AD9361 DAC power

Hi,

 

I want to ask that in AD9361, we have a 12-bit DAC. So when I used the linux drivers to transmit the BPSK waveform, I used the scaling factor of 2048. So samples were mapped like [1,-1] to [2048, -2048] but I did not get the required power. But then I thought that since the driver used 16 bit integer, therefore the mapping should be liked [1,-1] to [32767,-32767].

So is 32767 the correct scaling factor that will give me the maximum power out of the DAC ?
