6.3.3 Sensitivity Linearity

The device produces a linear response when the output voltage is within the specified VL range. Outside this range, sensitivity is reduced and nonlinear. Figure 6-3 graphs the magnetic response.

Equation 2 calculates parameter BL, the minimum linear sensing range at 25°C taking into account the maximum quiescent voltage and sensitivity tolerances.

The parameter SLE defines linearity error as the difference in sensitivity between any two positive B values, and any two negative B values, while the output is within the VL range.

The parameter SSE defines symmetry error as the difference in sensitivity between any positive B value and the negative B value of the same magnitude, while the output voltage is within the VL range.
