Contact MEMSIC for On-chip sensitivity compensation access to advanced calibration and tilt-compensation On-chip temperature sensor algorithms. Motion Detection and Data Ready Interrupt An integrated SET/RESET function provides for the Low power consumption elimination of error due to Null Field output change 1A power down current with temperature. Temperature information from the 2 I C Slave, FAST( 400KHz) mode integrated temperature sensor is available over the 2 2.5V single low power supply I C Interface. The SET/RESET function can be 2 1.8V I C interface performed for each measurement, periodically, or RoHS compliant when the temperature changes by a predetermined P2P compatible with HMC5883L amount as the specific application requires. In addition, the SET/RESET function clears the APPLICATIONS sensors of any residual magnetic polarization resulting Electronic Compass & Navigation from exposure to strong external magnets. Position Sensing The MMC5883MA is packaged in a low profile LGA General Purpose Magnetic Field package (3.0 x 3.0 x 1.0 mm) and an operating Measurements temperature range from -40 C to +85 C. 2 The MMC5883MA provides an I C digital output with DESCRIPTION 400 KHz, fast mode operation. The MMC5883MA is a complete 3-axis magnetic sensor with on-chip signal processing and integrated 2 I C bus suitable for use in various applications. 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 8Gauss (G), with 0.25mG per LSB resolution at 16bits operation mode and 0.4mG total MEMSIC, Inc.
