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 DFN6 package |
