Application circuit

The TLE5309D sensor can be used in single-ended or differential output mode. Figure 9 shows a typical

application circuit for the TLE5309D in single-ended output mode using the positive output channels. For

single-ended operation the positive or negative output channels can be used. Unused single-ended output

pins should preferably be floating or connected to GND with a high-ohmic resistance (> 100 kΩ). The TLE5309D

has separate supply pins for the GMR sensor and the AMR sensor. The microcontroller comprises up to 10 A/D

inputs used to receive the sensor output signals in differential output mode, illustrated in Figure 10. For

reasons of EMC and output filtering, the following RC low pass arrangement is recommended. The RC low pass
