† _{Voltage reference input applies to the externally applied voltage (overdrive condition). Internally a 2 kΩ resistor isolates the internal reference}
from the externally applied voltage, if any.
NOTE 3: The combination of Vref and RFS can be chosen at will as long as the maximum full-scale DAC output current I(FS) does not exceed 120%
of its nominal value. Therefore, at fixed R(FS) = R(FSnom), Vref should not be higher than the maximum value mentioned and at fixed
Vref = Vref(nom), R(FS) should not be less than the minimum value mentioned.
