Application information
20/26
The resistor ratio K1= R
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
amplification gain Av are important parameters and must therefore be selected carefully.
