MEMSIC MMC3630KJ Rev.A FUNCTIONAL BLOCK DIAGRAM magnetic fields within the full scale range of 30 Gauss (G), with 1 mG per LSB resolution at 16 bits operation mode and 2 mG total 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. 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 MMC3630KJ is packaged in an ultra-small low profile BGA package (1.2x 1.2 x 0.5 mm) and with an operating temperature range from -40 C to +85 C. The MMC3630KJ provides an I2C digital output with 400 KHz, fast mode operation. MEMSIC, Inc.
