Figure 7. TRACKER NSE-5310 Evaluation Board
Figure 7
shows NSE-5310 mounted on a PCB with FPC connector for ease of handling. A multipole linear magnetic strip is positioned above the
sensor.
8.1 Hall Sensor Array
Eight Hall Sensor Front End cells are connected to two current summation busses which end into two Active Load circuits. The Hall elements are
arranged in an even linear array. The array is divided into four quadrants. For normal operation (position encoding), two opposite quadrants are
summed up differentially to neglect magnetic offsets. The 90 degree angular shift of the quadrant pairs produces 90 degree phase shifted SIN
and COS signals for a harmonic input signal provided by a diametrically magnetized source.
