Analog Devices Inc. Magnetic Field Sensors
Analog Devices Inc. Magnetic Field Sensors detect and measure magnetic fields around permanent magnets, current conductors, and electrical devices. These magnetic field sensors create accurate and space-efficient solutions that operate with little power. Analog Devices’ Magneto Resistive Sensing Technologies, signal conditioning capabilities, and deep domain expertise enable innovative, high-performance sensing solutions for position and current measurements across various applications and markets.
Position sensors are available in single-turn and multiturn configurations. Single-turn position sensors measure a single rotation, while multiturn sensors measure multiple rotations, even in the absence of power. The ADI MagIC+ current sensors utilize AMR platforms to enable innovative sensing technologies and deliver radical improvements over incumbent core-based Hall technology or CT-based solutions.
