Magnetic sensor fits mobile devices

April 04, 2016 // By Susan Nordyk
The MMC3630KJ magnetometer from MEMSIC integrates a monolithic 3-axis AMR (anisotropic magnetoresistive) sensor and a signal conditioning ASIC into a 1.2 × 1.2 × 0.5-mm BGA package.

According to the manufacturer, devices in the series offer the ability to deliver a magnetic sensitivity in a range of ±30 Gauss and achieve a noise level that is five times better than other technologies.

 

Aimed at wearable and mobile device markets worldwide, the MMC3630KJ has a magnetic sensing bandwidth of 600 Hz and provides accuracy of greater than ±1° in eCompass applications. MEMSIC also reports that the design of the MMC3630KJ magnetometer can drastically lower system-level power consumption and processing time. Device features include self-degaussing and a power-saving interrupt function.
