Note: 1: 1.62V is the minimum operation voltage, or VDA / VDD should not be lower than 1.62V.
2: Power consumption is proportional to how many measurements performed per second, for example, at one
measurement per second, the power consumption will be 0.1mA/7=0.014mA.
3: MEMSIC product is with low noise and enables users to utilize heading accuracy to be 0.5 degree typical
and 1.0degree maximum when using MEMSIC‟s proprietary software or algorithm
4. The error can be eliminated by using SET and RESET to determine the true Null Field output for each
measurement.
