Differential Mode SDADC Codes

I need to know what the differential mode SDADC conversion code is. Is it 2's compliment such that the code:

  int16_t D = (int16_t)HAL_SDADC_GetValue(&hsdadc3);

Will return to D a signed result such that if the positive input is less than the negative input D will be a negative value and that:

  float V = D * VDDA / (1 << 16);


will result in V being the signed voltage across the inputs? (Assuming unity gain.)

I have looked for this in the documentation and I cannot find it. It would help for me to know where this is.

The processor is an STM32F373VCT.
