The MMC3120MR is designed using anisotropic magnetoresistive (AMR) technology, which provides "much better competitive advantages than other magnetic sensor technologies in the market (Hall sensor, GMR, etc)." The MMC3120MR has significant benefits in terms of current consumption (0.55 ma), measuring time (5 ms), sensitivity (2 mG/LSB) and accuracy (± 2°).
MEMSIC's new MMC3120MR integrates three-axis magnetic sensors and electronic circuits, resulting in an easy-to-use solution for system designers. It uses the same AMR technology as MEMSIC's MMC3120MQ magnetic sensor product, but the MMC3120MR is packaged in a significantly smaller package (3 by 3 by 1 mm), which is important to board space–critical applications such as mobile handsets.
The MMC3120MR and the recently released MMC2120MR work with MEMSIC's Intelligent Heading Correction library of auto-calibration and dynamic-compensation algorithms to provide industry-leading compass performance. MEMSIC's flexible software library is available to adapt to either dual or tri-axis magnetic sensors upon customers' request.
Pricing for this product starts at $1.90 per unit for 1000 units.
