1. The product is factory calibrated at 2.5 V. The operational power supply range is from 1.71 V to 3.6 V.

2. Typical specifications are not guaranteed.

3. Verified by wafer level test and measurement of initial offset and sensitivity.

4. Offset can be eliminated by enabling the built-in high-pass filter.

5. “Self-test positive difference” is defined as: OUTPUT[mg](CTRL5 ST2, ST1 bits=01) - OUTPUT[mg](CTRL5 ST2, ST1 bits=00).
