CC
 = 12 V.
2
Maximum voltage must be adjusted for power dissipation and junction temperature; see Power Derating section.
3
Negative current is defined as current coming out of (sourced from) the specified device terminal.
4
Sustained voltages beyond the clamp voltage may cause permanent damage to the IC.
5
1 G (gauss) = 0.1 mT (millitesla).
6
The repeatability specification is based on statistical evaluation of a sample population, evaluated at 1000 Hz.
7
Power-on frequencies d 200 Hz. Higher power-on frequencies may result in a delay of full output accuracy or undetected target edges.
8
Excludes effects caused by signature region.
