Memsic has announced the MMC5883MA 3-Axis Magnetic Sensor for broad application including industrial, drone, wearable, medical and mobile. Such applications require detection of motion, acceleration and directional sensing. Design of such devices needs mixed-signal processing, low power and compact in size. Because of the strength of the signal from the sensor is usually small, it demands strong signal-to-noise ratio. Meeting all these requirements can be challenging. Based on its long history of proprietary technology, Memsic delivers the anisotropic magneto resistive (AMR) based Magnetic Sensor comes in a low profile LGA package of 3.0 x 3.0 x 1.0 mm. Each of its 3-axis is a16-bit operation over a ± 8 Gauss operating range (FSR) with linearity of ± 0.2 percent FSR, hysteresis of 0.2 percent FSR and repeatability of 0.2 percent FSR.

At seven samples per second data rate the current consumption is 20 uA with noise level of 0.4 mGauss total RMS. Input voltage ranges from 2.16 to 3.6 volts and temperature range is from -40 to + 85 degrees C. The MC5883MA incorporates an on-chip signal processing and an integrated I2C 400 kHz FAST mode operation digital interface enables direct connection to the system microprocessor. A Universal Evaluation Board with the devices pre-mounted is available for product development and data logging. Products are available in volume.
