1.1 Introduction

The TMAG5170 is a 3-axis linear Hall effect sensor. This device integrates three independent Hall sensors in X, Y, and Z axes. A precision analog signal-chain along with integrated 12-bit ADC digitizes the measured analog magnetic field values. The device can be configured further to select one of three magnetic field ranges that suits the magnet strength and component placements during system calibration.
