Application Hints
The application mode of the GMR position sensor is preferably as a bridge or halfbridge
circuit. This circuit compensates for the
T
C
of the resistance value
R
0
. To compensate
for the
T
C
of the GMR effect
R
/
R
0
, if there is the necessity, is left to the application circuit
and can be done for example with a NIC circuit. When operated over a complete 360
°
turn, two total signals of
>
20 mV/V are achieved at 25
°
C with two halfbridges. In the
case of linear position sensing, the electrical circuit remains unchanged, also providing
two phaseshifted signals (i.e.sine and cosine).
