Typical values are at T
Maximum voltage must be adjusted for power dissipation and junction temperature; see Power Derating section.
Please refer to Sensor Operation section, page 13.
Power-On Time includes the time required to complete the internal automatic offset adjust. The DACs are then ready for peak acquisition.
dI is the difference between 10% of I
Functional characteristics valid only if magnetic offset is within the specified range for Allowable User Induced Differential Offset.
AG is dependent on the available magnetic field. The available field is dependent on target geometry and material, and should be independently char-

In order to remain in specification, the magnetic gradient must induce an operating signal greater than the minimum value specified. This includes the
