3.1
The advantage of the current interface is, that only two wires are necessary to connect the sensor.
At least one series resistor is required to convert the two output states of the Hall sensor from current consumption
to a voltage information.
A typical value for R
On state.
If the sensor is operated in an application environment with disturbances on the supply line, an additional series
resistor R
formula:
V
