The MMC3316xMT is a complete 3-axis magnetic sensor with on-chip signal processing and integrated I2C bus. The device can be connected directly to a microprocessor, eliminating the need for A/D converters or timing resources. It can measure magnetic fields within the full scale range of +/-16 Gauss, with 2mG/LSB resolution and 2mG rms noise,
enabling  heading accuracies of <1 degree in electronic compass applications.

An integrated SET/RESET function provides for the elimination of error due to Null Field output change with temperature. In addition it clears the sensors of any residual magnetic polarization resulting from exposure to strong external magnets. The SET/RESET function can be performed for each measurement or periodically as the specific application requires.
The MMC3316xMT is packaged in a small low profile LGA package (2.0 x 2.0 x 1.0 mm) and has an operating temperature range from -40C to +85C.
