설명
The MMC3630KJ is a complete 3-axis magneticsensor with on-chip signal processing and integratedI2C bus. The device can be connected directly to amicroprocessor, eliminating the need for A/Dconverters or timing resources. It can measuremagnetic fields within the full scale range of 30Gauss (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 electroniccompass applications. Contact MEMSIC for access toadvanced calibration and tilt-compensation algorithms.An integrated SET/RESET function provides for theelimination of error due to Null Field output changewith temperature. In addition it clears the sensors ofany residual magnetic polarization resulting fromexposure to strong external magnets. TheSET/RESET function can be performed for eachmeasurement or periodically as the specificapplication requires.The MMC3630KJ is packaged in an ultra-small lowprofile BGA package (1.2x 1.2 x 0.5 mm) and with anoperating temperature range from -40 °C to +85 °C.The MMC3630KJ provides an I2C digital output with400 KHz, fast mode operation.
