1. Typical specifications are not guaranteed.

2. Values after factory calibration test and trimming.

3. Measurements are performed in a uniform temperature setup and they are based on characterization data in a limited

number of samples, not measured during final test for production.

4. Based on characterization data on a limited number of samples, not measured during final test for production.

5. Excluding drift due to magnetic shock.

6. With low-pass filter or offset cancellation enabled.

7. “Self-test” is defined as: OUTPUT[gauss](Self-test enabled) - OUTPUT[gauss](Self-test disabled).
