Smart Sensors
SM228-10E: Smart TMR Magnetometer, 15 mT, I2C, TDFN6
The SM228-10E Smart Magnetometer combines a Tunneling Magnetoresistance (TMR) sensor element with
sophisticated digital signal processing for a unique combination of speed and precision. An I2C 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
• I2C interface
• Programmable digital threshold output
• 2% of full-scale accuracy for 0 to 125°C
• Fast 10000 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 DFN6 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
