External resistors are required if they are not internal to the sensor. The pull-up resistor (R) value depends on
the power supply value. The table below shows the maximum resistor values for typical supply voltages. To
calculate the maximum resistor value, use the following formula:
where:
R = maximum pull-up resistor value
VDC = power supply voltage
Vmin = 2.6V DC
Imin = 6.8 mA
The minimum resistor (R) value depends on the current sinking capability of the
sensor. Refer to your sensor’s documentation.
