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

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 voltage input:

Resolution =

(Gain value) - (Offset value)

4000

 

(b) For the current input:

Resolution =

(Gain value) - (Offset value)

4000

 

(2)Relationship between the maximum resolution and digital output value

The maximum resolution of the AJ65SBT-64AD 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)

< Maximum resolution

4000

 

3.3.4 Accuracy

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 ±0.4% (±16 digit) at the operating ambient temperature of 0 to 55°C.
