^[1]1 G (gauss) = 0.1 mT (millitesla).

Angular Position

(%)

^[2]Operation guaranteed down to 4.5 V, once V_CChas risen above 4.65 V.

^[3]At power-on, the sensor IC will not respond to commands until V_CCrises above V_UVLO(H). After that,

the sensor IC will perform and respond normally until V_CCdrops below V_UVLO(L)

Transducer Output

^[4]Parameter is not guaranteed at ﬁnal test. Values for this characteristic are determined by design.

^[5]RES_ANGLErepresents the number of bits of internal angle information available.

^[6]The rate at which a new angle reading will be ready.

^[7]Maximum of 1.0 degree increase in angle error observed following AEC-Q100 stress.
