Magnetic sensor stabilizes drone designs
Housed in a tiny 3.0×3.0×1.0-mm LGA package, the MMC5883MA integrates on-chip signal processing and an I2C fast-mode (400 kHz) digital interface for direct connection to a system microprocessor. It allows engineers to add stability and direction sensing to their designs, leveraging fast algorithms for hard- and soft-iron interference correction to achieve more precise and faster heading determination.
The MMC5883MA operates over a temperature range of -40°C to +85°C from a supply voltage of 2.16 V to 3.6 V. Current consumption is only 20 µA at a data rate of 7 samples/s. Further, the part exhibits an extremely low noise level of just 0.4 milligauss RMS.
The three-axis magnetic sensor is now in production and available immediately. Devices premounted on prototyping boards can be purchased directly from MEMSIC. Designers can evaluate and log data using MEMSIC’s universal evaluation board.
A datasheet for the MMC5883MA was not available at the time of this announcement.
