8.1.1.2.1 1. Determine the value of R1 AND R2
The output voltage is determined by the value of the voltage-divider resistor, R1 and R2 as shown in Figure 36. R1 is connected between VREF and REFIN pins, and R2 is connected between the REFIN pin and GND. Setting R1 as 10-kΩ is a good starting point. Determine R2 using Equation 6.
