(1)

1 mT = 10 Gauss

(2)

Bandwidth describes the fastest changing magnetic field that can be detected and translated to the output.

(3)

Not tested in production; limits are based on characterization data.

(4)

Linearity describes the change in sensitivity across the B-range. The sensitivity near BSAT is typically within 1% of the sensitivity near

B = 0.
