SM228-10E: Smart TMR Magnetometer, 15 mT, I2C, TDFN6

The SM228-10E Smart Magnetometer combines a Tunneling Magnetoresistance (TMR) sensor element with sophisticated digital signal processing for a unique combination of speed and precision. An I2C 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
  •  I2C interface
  •  Programmable digital threshold output
  •  2% of full-scale accuracy for 0 to 125°C
  •  Fast 10000 sample-per-second update rate
  •  Factory calibrated
  •  Programmable offset and gain compensation
  •  -40°C to +125°C operating range
  •  Ultraminiature 2.5 x 2.5 mm DFN6 package
