±2 LSB Absolute Accuracy
±1 LSB Typical Accuracy
Total board error is a combination of Gain, Offset, Differential Linearity and Integral Linearity error. The
theoretical absolute accuracy of the board may be calculated by summing these component errors. Worst case error
is realized only in the unlikely event that each of the component errors are at their maximum level, and causing
error in the same direction.

Analog Output Zero drift
±0.22 LSB/°C max
Analog Output Full-Scale Gain drift
Absolute error change per °C Temperature change is a combination of the Gain and Offset drift of many
components. The theoretical worst case error of the board may be calculated by summing these component errors.
Worst case error is realized only in the unlikely event that each of the component errors are at their maximum
level, and causing error in the same direction.
