1Typical data is at VCC = 8 V and TA = 25°C. Performance may vary for individual units, within the specified maximum and minimum limits.

2 Maximum voltage must be adjusted for power dissipation and junction temperature; see Power Derating section.

3 CS is the probe capacitance of the oscilloscope used to make the measurement.

4 10 G = 1 mT (millitesla), exactly.

5Non-uniform magnetic profiles may require additional edges before calibration is complete.
