Typical values are at T
Maximum voltage must be adjusted for power dissipation and junction temperature; see Power Derating section.
Please refer to Device Operation section.
Power-On Time includes the time required to complete the internal automatic offset adjust. The DAC is then ready for peak acquisition.
dI is the difference between 10% of I
Functional characteristics valid only if magnetic offset is within the specifi ed range for Allowable User Induced Differential Offset.
In order to remain in specifi cation, the magnetic gradient must induce an operating signal greater than the minimum value specifi ed. This includes the
