ADVANCE INFORMATION
Offset drift is defined as the change in offset voltage measured at multiple points over the specified temperature range. Offset drift is calculated using the box method where a box is formed over the maximum and minimum offset voltages and specified temperature range. The box method specifies limits for the temperature error but does not specify the exact shape and slope of the device under test.
Equation 1 shows the offset drift calculation using the box method:
