Hi,

I'm trying to use this OPAMP. In the Datasheet there is a circuit Figure 140 Adding an Atteunator... on Page 35 (RevC).

I think the given equation is not correct. I suppose that the equation is

Vout= ((Vin)*((Rf/Rg)+1)) + (Voffset*(Rg/(Rf+Rg))*(Rf/Rg)+1))

Could you control this?

Thank you in advice and best regards

Serhat

Hi Serhat,

I don't know if you've worked through this yet, but I think your equation is correct, and it simplifies to what is shown in figure 140.

Regards,

Dave
