(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 B_SAT is typically within 1% of the sensitivity near
B = 0.
