    1 Overview The TMAG5170D is a dual-die, 3-axis linear Hall-effect sensor. This device integrates three independent Hall sensors in X, Y, and Z axes on each die. 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.

    (EMC) testing. The EVM has both sensitivity variations of the TMAG5170D installed, and may be broken into two separate boards as needed. The EVM is intended to interface with the TI-SCB, but may be used as a stand-alone device if desired.

  • Page 10 This error may vary based on the installation of either the magnet or sensor within the system. Often, end-of-line calibration for each sensor is required after full system assembly to achieve the best results. For more information, refer to the Texas Instruments Achieving Highest System Angle Sensing Accuracy application note.
