Temperature (°C) 125 Package 2.5 x 2.5 mm DFN6 Data Sheet (.pdf) Package Outline (.pdf) STEP File (.step) KiCAD Footprints (External Link) × × Model for 2.5-x-2.5-mm-DFN6 Description: The SM225-10E Smart Magnetometer combines a Tunneling Magnetoresistance (TMR) sensor element with sophisticated digital signal processing for a unique combination of speed and precision. An SPI interface provides data as well as an external programming interface.

Unlike awkward, old-fashioned Hall-effect sensors, TMR is sensitive in-plane for optimal current sensing and easy mechanical interfaces. Key features include:
  •  0 to 150 Oe / 0 to 15 mT linear range
  •  Can detect magnets more than 50 mm away
  •  SPI interface
  •  2% of full-scale accuracy for 0 to 125°C
  •  Fast 15000 sample-per-second update rate
  •  Factory calibrated
  •  Programmable offset and gain compensation
  •  -40°C to +125°C operating range
