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

(1) Precision at 5V input;
4000 × 0.5% = 20
Therefore, precision range at 5V input is; (2000-20) ~ (2000+20) = 1980 ~ 2020.
(2) Precision at 10V input;
4000 × 0.5% = 20
Therefore, precision range at 10V input is;(4000-20) ~ (4000+20) = 3980 ~ 4020.
