13.4 Accuracy
13.4.1 Input Accuracy
Accuracy of digital output value does not changed even if input range is changed. Figure below shows the range of
the accuracy with analog input range of 0 to 10 V and digital output type of unsigned value selected.
Accuracy is ±0.2% (Ambient temperature of 25±5℃).

Digital output value
(1) Accuracy when using 5 V input
16,000 × 0.2% = 32
Therefore the range of the accuracy will become (8,000-32) to (8,000+32) = 7,968 to 8,032
when using 5 V input.
(2) Accuracy when using 10 V input
16,000 × 0.2% = 32
Therefore the range of the accuracy will become (16,000-32) to (16,000+32) = 15,968 to 16,032
when using 10 V input.
