The following table outlines the resistor required: Supply Voltage (V) Set Temperature (°C) 5 8 10 12 15 18 20 24 28 Required external resistor (kΩ) To calculate resistor for temperature not on the chart use the following formula: R = e(ln(R2/R1) * (TS – T1) / (T2 – T1) + ln(R1)) Where: R = resistor value required for temperature TS. TS = Temperature desired T2 = Temperature just above TS R2 = Resistor value corresponding to T2 T1 = Temperature just below TS R1 = Resistor value corresponding to T1
