PRODUCTION DATA.
The DAC output can be configured to be either in ratiometric-to-PWR mode or independent-of-PWR (or absolute) mode using the DAC_RATIOMETRIC bit in the DAC_CONFIG register.
NOTE
In ratiometric mode, changes in the VPWR voltage result in a proportional change in the DAC output voltage because the reference for the DAC is derived from VPWR.
