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
