As shown in the figure, when the output current exceeds 40mA, the internal 50Ω resistor (R9) of XTR110 needs to be replaced by an external resistor REXT, and REXT is connected between pins 13 and 16. REXT = R9 (original span / required span). For example, in the figure, the original span of XTR110 is 20mA, and the required span is now 10A, R9 = 50Ω, then REXT = R9 = 50 × (20/10000) = 0.1Ω.
