SM-Series Smart Sensors combine a GMR or TMR sensor element with digital signal processing to provide precise magnetic field measurements with high accuracy over the full -40 to +125C temperature range.

SPI, I²C, and PWM interfaces are available for linear sensing. Additionally, SM-series smart sensors can be used as precision one-time programmable magnetic limit switches.

GMR and TMR sensor elements are sensitive in-plane for optimal current sensing and easy PCB orientations. TMR also provides more sensitivity, higher precision, higher speed, and lower noise than Hall effect sensors.

The device is factory calibrated for high accuracy, and calibration coefficients are stored in internal nonvolatile memory.
