5.1.4 Resistors and Inputs Connected in Parallel
Parallel resistance Rp: FX1N = 15kΩ. If resistance Rp is less than the stated value, then add
Rb. See equation 1 for Rb calculation.
Alternatively; Current leakage: FX1N = 1.5mA. If the current leakage is greater than the stated
value, then add Rb. See equation 2 for Rb calculation.
