SM125-10E: General-Purpose 4 mT Smart GMR Magnetometer, DFN6

  • Part Number
  • SM125-10E
  • Resolution (bits)
  • Supply Current @ 3.3 V (µA)
  • Max. Temperature (°C)

Description:

The SM125-10E Smart Magnetometer combines an omnipolar GMR sensor element with with easy-to-use digital signal processing.

A digital output provides precise, programmable thresholds. An I²C interface provides magnetic field data, as well as a calibration interface. The device is factory calibrated for accuracy. Calibration coefficients are stored in internal nonvolatile memory.

All commands, data, and coefficients are a single byte, and a slick, elegant data structure lets you get up and running with a minimum of firmware.

Key features include:
  • Can detect magnets more than 50 mm away
  • I²C and digital threshold outputs
  • 0-4 mT linear range
  • 8-bit / 1% output resolution
  • −40°C to +125°C operating range
  • 5% FS accuracy for 0 to 85°C
  • 10 kSps sample rate for fast response
  • 6 mA typical supply current
  • In-plane sensitivity more usable than Hall effect sensors
  • Programmable offset and gain compensation
  • Optional magnet temperature compensation   • 2.2 to 3.6 volt supply
  • Ultraminiature 2.5 x 2.5 x 0.8 mm DFN6 package
