I have been reading these posts, and I must say there are some very bright individuals in here:) anyways, I would like to use this cIrcuit to measure the voltage of a power supply output, however it is 0-25.2 VAC not DC, is there a mod I can implement that will allow this?? I will use a separate power supply for the + and - 5v. I saw in the spec sheet in figure 21 that a AC to DC convertor with the ICL7106 can be used?? Can i simply implement that circuit?? I'm a newbie at this stuff, so please forgive my ignorance!!!
