The resistor ratio K1= R
g3
/R
g1
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 SEL1 and SEL2 pins. Since
they define the full-scale output range of the application, the R
sense
resistor and the
amplification gain Av are important parameters and must therefore be selected carefully.
