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
