3,4 is without amp, and 1,2 is with amp.
I wonder before amp, the divider values are same, but after combining amp, why is the ouput of fig1 and 2 different?
if the input values are same such as 676.7mV, I think the amplifier values should be 676.7mV.
however fig 1 is 590.2mV and fig 2 is 523.3mV. can you tell me the reason?
