Angle sensor with integrated amplifier
10. Definitions of errors
10.1 Reference position angle error
The reference position angle error 
err
is defined as absolute mounting position deviation
of the MR sensor in a homogeneous excitation magnetic field related to the reference
position
0
defined by the leadframe. Marking position for angle
0
= 0 degree and Y = 0
position is referred parallel to the straight connection line of the 2nd and 7th package pin.
The X = 0 position is referred to the middle distance of the package top (see Figure 3
).
10.2 Output amplitude matching error
The output amplitude matching error k is defined as the relation between both output
channel amplitudes at continuously rotating magnetic excitation of the MR sensor.
k=100 V
o(VOUT1)
(p-p) / V
o(VOUT2)
(p-p) (the angle error can be derived from Figure 4)
