The flux density measured by the A1351 SIP is related to the
size of the gap cut into the core. The larger the gap in the core,
the smaller the flux density per ampere of applied current (see
figure 8).
Figure 9 depicts the magnetic flux density through the center of
the SIP as a function of SIP to core alignment. Note that a core
with a larger cross-sectional area would reduce the attenuation
in flux density that results from any SIP misalignment. The flat
portion of the curve in figure 9 would span a larger distance in
millimeters if the cross-sectional area of the core were increased.

Figure 8. The flux density per ampere measured by the A1351 Hall device
is related to the core gap, as shown. This figure assumes that the current
sensing application is constructed using the example setup.
