7.2.1.1 Gain Adjustment for Angle Measurement

Common measurement topology include angular position measurements in on-axis or off-axis angular measurements shown in Figure 7-5. Select the on-axis measurement topology whenever possible, as this offers the best optimization of magnetic field and the device measurement ranges. The TMAG5170D-Q1 offers an on-chip gain adjustment option to account for mechanical position misalignments.
