Abstract
A Hall sensor (HS) comprises at least four sensor terminals (EXT_A, EXT_B, EXT_C, EXT_D) for connecting the Hall sensor (HS) in at least two Hall sensing elements () connected together, element terminals (A, B, C, D) of the Hall sensing elements () are connected in between the sensor terminals (EXT_A, EXT_B, EXT_C, EXT_D). Each of the Hall sensing elements () is configured to provide an individual sensor value between two of its element terminals (A, B, C, D). The at least two Hall sensing elements () are distributed basically equally into two halves (B, B) and are connected such that a difference value is electrically formed between two of the sensor terminals (EXT_A, EXT_B, EXT_C, EXT_D) resulting from the respective individual sensor values. The individual sensor values of one half (B) form a minuend of the difference value and the individual sensor values of the other half (B) form a subtrahend of the difference value such that the minuend and the subtrahend cancel out each other in case a homogeneous magnetic field of the same intensity and the same direction is applied to both halves (B, B).
