In the data sheet page 3, the Vref+ is specified as: Vss + 6 to Vdd - 6, so if Vss = -15V, Vdd = 15V, then the allowed Vref+ should be: -9V min and 9V max. But in page 7, it states:


VREF+ Input. The DAC is specified for VREF+ of 5 V. The DAC is fully multiplying so that the VREF+ range is +5 V to –5 V.


Then, what does it mean? Can I achieve 'full multiplying' when the range of VREF+ is a AC signal swing between +9V and -9V?
