Typical data is at V
1 G (gauss) = 0.1 mT (millitesla).
The device compensates for magnetic and installation offsets. Offsets greater than specification in gauss may cause inaccuracies in the output.
For power-on S
Operational Air Gap Range is dependent on the available magnetic field. The available field is target geometry and material dependent and should be
The repeatability specification is based on statistical evaluation of a sample population, evaluated at 1000 Hz. Repeatability is measured at 150°C
Single maximum allowable air gap change in outward direction (increase in air gap).
Maximum voltage must be adjusted for power dissipation and junction temperature; see Power Derating section.
Power-On Time is the time required to complete the internal Automatic Offset Adjust; the DACs are then ready for peak acquisition.
