Note that at low DCVDD voltages, the output range of the AUXDAC becomes limited, so that its
maximum RMS output voltage is the lesser of:
Under these circumstances, the AUXDAC cannot convert high digital input values to the correct
analogue equivalent; its digital input range must therefore be limited accordingly. If necessary, this
limitation can be circumvented by setting gains for the AUXDAC signal in register 12h, or by using a
higher DCVDD voltage.
