1.3. Offset and sensitivity calibration

Vout offset is calibrated in 0g position:

Offset = Vout (0g ) [V]

Nominal offset is Vdd/2:

Offset nom

= Vdd

2

[V]

Sensitivity is calibrated as:

Sensitivity = Vout (+ 1g ) − Vout (−1g ) [V/g]

2g

Nominal sensitivity is:

Sensitivitynom = 1,2 [V/g]

1.4. Error calculations

Total error is the allowed maximum error, which include partial error sources. Total error over

lifetime is specified as a sum of offset and sensitivity errors:

Total _ Error = Offset _ Error + Sensitivity _ Error [mg]

Offset error is specified as:

Vout(0g ) − Vdd

Offset _ Error =

2 [mg]

Sensitivity

Sensitivity error percent is specified as:

Sensitivity _ Error% = [Vout(+ 1g ) −Vout(−1g )] 2 g − Sensitivitynom ×100%

Sensitivitynom

Sensitivity error is specified as:

[Vout − Vout(0g )]× Sensitivity _ Error%

Sensitivity _ Error =

[mg]
