Summary:A Hall device is formed from a generally rectangular body of material exhibiting the Hall effect, with two excitation electrodes disposed along opposite edges of the device. Two Hall output voltage electrodes are disposed along one of the remaining edges of the main body and at least one additional output electrode is disposed on the edge of the main body opposite the first pair of electrodes. At least two of the output electrodes are offset from a centerline drawn through the electrical midpoint of the main body. By deliberately offsetting the Hall voltage output electrodes from the centerline the first and second order voltage offsets due to inhomogeneities of the Hall material and mask misalignment are eliminated or easily compensated.
