4 Summary

AMR sensors provide benefits like reducing input noise and greatly improving response time when compared to traditional Hall-effect sensors. Creating non-linearity in the output response is possible by providing an input with non-linear angle change since these AMR sensors are designed to measure the angle of the input magnetic field vector in 2D space.

TI's Magnetic Sense Simulator (TIMSS) offers a convenient method to simulate magnetic fields and estimate device response. Using this tool allows users to create a rotating magnet and produce plots and data reports of the expected magnetic field and device response. These functions help users better understand what to expect before prototyping.
