Hi I just posted this but it did not go through...sorry if this ends up being a duplicate post
What I need is for the 0-5v output of the dac to go into the galvo unit which has a 3 pin input (+, g, -)
I think the 0-5v needs to be converted into a seperate 0 to 5v and -5 to 0v outputs.
I think the dual opamp is used by doubling the voltage (0 to 10v) shifting it to -5v to 5v then one opamp is used to cutt off the upper half of the signal giving me -5 to 0v out and the second OPamp does the opposite giving me the 0v to 5v part of the signal.... I am new to electronics so its just a guess and even if Im right, I have no idea how to accomplish this...
the output of the dac is a constantly changing signal that will control the mirror position of the galvonometer...
