6 _{Please contact Melexis for Timing specification for “L” Temperature suffix}
7 _{Sensitivity monitors enable (See section 18). Beyond that frequency, the Sensitivity monitor should be disabled.}
8 _{Limitation linked to the Automatic Gain Control. Beyond that frequency, there is a reduced immunity to norm change (like}
vibration). See also Section 19.4.
