Figure 46. Unipolar Output Mode of DAC8831
Assuming a perfect reference, the worst-case output voltage may be calculated from the following equation:
Unipolar Mode Worst-Case Output
Where:
VOUT_UNI = Unipolar mode worst-case output
D = Code loaded to DAC
VREF = Reference voltage applied to part
VGE = Gain error in volts
VZSE = Zero-scale error in volts
INL = Integral nonlinearity in volts
