The MMC3616xPJ is a complete 3-axis magnetic sensor with on-chip signal processing and integrated I2C bus. The device can be connected directly to a microprocessor, eliminating the need for A/D converters or timing resources. It can operate from a single 1.8 V supply. It can measure magnetic fields within the full scale range of +/-16 Gauss, with 0.5 mG/LSB resolution and 1.5 mG rms noise,
enabling  heading accuracies of <1 degree in electronic compass applications.

An on demand 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 on demand SET/RESET function can be performed for each measurement or periodically as the specific application requires providing the flexibilty to maximize perfomance while minimizing power consumption.
The MMC3416xPJ is packaged in a small low profile LGA package (1.6 x 1.6 x 0.6 mm) and has an operating temperature range from -40C to +85C.
