The World's 1st TMR Smart Magnetometer from NVE

The new SM324-10E Smart Magnetometer combines a Tunneling Magnetoresistance (TMR) sensor element with sophisticated digital signal processing.

An I²C interface provides data as well as an external programming interface. 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 SM324-10E features and specifications include:
  •  Can detect magnets more than 50 mm away
  •  I²C and digital threshold outputs
  •  24-bit output resolution
  •  ±0.3% FS accuracy at 25°C
  •  300 samples/second conversion rate
  •  0 to ±20 Oe magnetic field operating range
  •  1.68 to 3.6 volt supply
  •  1.5 mA typical supply current
  •  Programmable offset and gain compensation
  •  -40°C to +125°C operating range
  •  Ultraminiature 2.5 x 2.5 x 0.8 mm TDFN package
