SM225-10E: High-Speed Smart TMR Magnetometer, 15mT, SPI, TDFN6

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
  •  Ultraminiature 2.5 x 2.5 mm TDFN package

SM324-10E: Ultraprecise Smart TMR Magnetometer, I2C, DFN6

The SM324-10E Smart Magnetometer combines a Tunneling Magnetoresistance (TMR) sensor element with sophisticated digital signal processing for unmatched accuracy and precision. An I²C interface provides data as well as an external programming interface, and a digital output provides precise, programmable thresholds.

Unlike awkward, old-fashioned Hall-effect sensors, TMR is sensitive in-plane for optimal current sensing and easy mechanical interfaces. Key features include:
  • -2 to +2 mT
  • Detects polarity
  • Can detect magnets more than 50 mm away
  • I²C and digital threshold outputs
  • 24-bit output resolution
  • In-plane sensitivity more usable than Hall effect sensors
  • Programmable offset and gain compensation
  • Calibrated internal temperature sensor
  • Internal temperature compensation
  • 1.68 to 3.6 volt supply
  • Ultraminiature 2.5 x 2.5 x 0.8 mm DFN package
