2.2.1 TMAG5170

The TMAG5170 is a high-precision linear 3D Hall-effect sensor designed for a wide range of industrial applications. The high level of integration offers flexibility and accuracy in a variety of position sensing systems. This device features 3 independent Hall sensors at X, Y, and Z axes. A precision signal-chain along with an integrated 12- bit ADC enables high accuracy and low drift magnetic field measurements while supporting a sampling of up to 20 kSPS. On-chip temperature sensor data is available for system-level drift compensation.
