MEMSIC MMC5883MA Rev.B FUNCTIONAL BLOCK DIAGRAM RMS noise level, enabling heading accuracy of 1º in electronic compass applications. Contact MEMSIC for access to advanced calibration and tilt-compensation algorithms. An integrated SET/RESET function provides for the elimination of error due to Null Field output change with temperature. Temperature information from the integrated temperature sensor is available over the I2C Interface. The SET/RESET function can be performed for each measurement, periodically, or when the temperature changes by a predetermined amount as the specific application requires. In addition, the SET/RESET function clears the sensors of any residual magnetic polarization resulting from exposure to strong external magnets. The MMC5883MA is packaged in a low profile LGA package (3.0 x 3.0 x 1.0 mm) and an operating temperature range from -40C to +85C. The MMC5883MA provides an I2C digital output with 400 KHz, fast mode operation. MEMSIC, Inc.
