Characteristic Allowable Signal Amplitude Variation
The colored area in figure 10 shows B
area of allowable magnetic signal amplitude within which the IC
will continue output switching. The output duty cycle is wholly
dependent on the magnetic signature of the target across the air
gap range of movement, and may not always be within specifi-
cation throughout the entire operating region (to B
Signal amplitude changes may be due to deflection (relative air
