The resistor ratio, K1 = Rg3/Rg1, is internally set to 20 V/V, and the voltage buffer gain, K2,

can be set to 1, 1.25, 2.5, or 5 depending on the voltage applied on the SEL1 and SEL2

pins. Since they define the full-scale output range of the application, the Rsense resistor and

the amplification gain Av are important parameters and must therefore be selected carefully.
