3.3.3 Relationship between the offset/gain setting and digital output value

3.3.4 Accuracy
3 - 6
The relationship between the offset/gain setting and digital output value is described.
(1) Resolution
The resolution is obtained by the following formula:
(a) For the AJ65VBTCU-68ADVN:
Resolution =
(b) For the AJ65VBTCU-68ADIN:
Resolution =
(2) Relationship between the maximum resolution and digital output
value
The maximum resolution of the AJ65VBTCU-68ADVN/ADIN is as indicated in the
performance specification.
If the following is satisfied from the offset/gain setting, the digital output value
does not increases /decreases by one.
(Gain value) - (Offset value)
4000
Accuracy is relative to the maximum value of the digital output value.
If you change the offset/gain setting or input range to change the input characteristic,
accuracy does not change and is held within the range indicated in the performance
specifications.
Accuracy is within ±0.2% (±8 digit) at the operating ambient temperature of 25±5°C or
within ±0.3% (±12 digit) at the operating ambient temperature of 0 to 55°C.
