MEMSIC MMC5603NJ 3-Axis AMR Magnetic Sensor
MEMSIC MMC5603NJ 3-axis AMR Magnetic Sensor features on-chip signal processing and an integrated digital bus (I2C fast mode and I3C interface) suitable for various applications. The device can be connected directly to a microprocessor, eliminating the need for A/D converters or timing resources. MEMSIC MMC5603NJ is available in a wafer-level package with an ultra-small size of 0.8mm x 0.8mm x 0.4mm and a -40°C to +85°C operating temperature range.
The sensor can measure magnetic fields within the full-scale range of ±30G, with up to 0.0625mG per LSB resolution at 20bits operation mode and 2mG total RMS noise level. This enables a heading accuracy of ±1° in electronic compass applications. An integrated SET/RESET function eliminates error due to Null Field output change with temperature. This function also 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.
