6.5.2 Output Precision
The precision of analog output is not dependent upon the output range.
The graph below shows the variation of precision when the analog output range is 0 ~ 10 V for
unsigned value for digital output.
The output precision of the XBF-AH04A is ±0.5%

(1) Precision at 5V output;
4000 × 0.5% = 20, therefore,
precision range at 5V output is; (5V - 20×0.0025V) ~ (5V+20×0.0025V) = 4.95 ~ 5.05V .
(2) Precision at 10V output;
4000 × 0.5% = 20, therefore,
precision range at 10V output is; (10V-20×0.0025V) ~ (5V+20×0.0025V) = 9.95 ~ 10.05V.
