Accuracy
While the update algorithm will allow the device to adapt to
typical air gap variations, major changes in air gap can adversely
affect switching performance. When characterizing IC perfor-
mance over a significant air gap range, be sure to re-power the
device at each test at different air gaps. This ensures that self-cal-
ibration occurs for each installation condition. See the Operating
Characteristics table and the charts in the Characteristic Data:
Relative Timing Accuracy section for performance information.
Repeatability
Repeatability measurement methodology has been formulated to
minimize the effect of test system jitter on device measurements.
By triggering the measurement instrument, such as an oscillo-
scope, close to the desired output edge, the speed variations that
occur within a single revolution of the target are effectively nul-
lified. Because the trigger event occurs a very short time before
the measured event, little opportunity is given for measurement
system jitter to impact the time-based measurements.
After the data is taken on the oscilloscope, statistical analysis
of the distribution is made to quantify variability and capabil-
ity. Although complete repeatability results can be found in the
Characteristic Data: Repeatability section, figure 11 shows the
correlation between magnetic signal strength and repeatability.
Because an direct relationship exists between magnetic signal
strength and repeatability, optimum repeatability performance
can be attained through minimizing the operating air gap and
optimizing the target design.
