Hi;
Have you tried to design a difference amplifier with ordinary low cost
op-amps and resistors. do you have a succesful circuit to share with
high CMRR? I want to read a high DC voltage but DC voltage notr is not
connected to my power supply notr, they are isolated. thats what I need
to do. any other idea to read that voltage rather than a differnce
amplifier? the output should be linear of course from 0 to 400V. thanks
in advance...
