Terminology

3.1

Sensitivity

Sensitivity describes the ratio of the output digital data expressed in LSB units and the

applied magnetic field expressed in mG (milligauss). It can be measured, for example, by

applying a known magnetic field along one axis and measuring the digital output of the

device.

3.2

Zero-gauss level

Zero-gauss level offset (TyOff) describes the deviation of an actual output signal from the

ideal output if no magnetic field is present.

3.3

Magnetic dynamic range

The magnetic dynamic range of the sensor can be fully exploited when the applied magnetic

field is entirely aligned with one of the sensitive axes of the sensor.

In the presence of a stray field in the cross-axis direction, the exploitable magnetic dynamic

range (maximum module) can decrease.
