The MMC3630KJ has the ability to reach ±30 G range, and more than 5x better noise level compared to other technologies. With 600 Hz magnetic sensing bandwidth, the MMC3630KJ is able to provide better than ±10 accuracy in eCompass applications. The design also has lower system- level power consumption and processing time.
The MMC3630KJ includes a self-degaussing feature, which can eliminate the output drift due to temperature change and residual magnetic from ambient magnetic field. The series also includes an interruption feature, which can be used for motion detection and data acquisition-ready notifications to lower system-level power consumption.
