masterleous Posted March 13, 2005 Report Share Posted March 13, 2005 Hi,In Electroni-LAB.com a circuit is given using IC 7107, The circuit is mainly for DC Inputs only, if we want to measure AC inputs than which changes will we have to make in our cisruits.Either, a Bridge Rectifier is used with capacitor in front of AC inputs and That Circuit for DC, or any other approach.

MP Posted March 13, 2005 Report Share Posted March 13, 2005 If you follow the long multi-page thread on the digital voltmeter, an AC input was added and posted in that area. You can perform a search of the digital voltmeter or look for last several posts by maestrodamus as he is the one who posted it.MP Quote Link to comment Share on other sites More sharing options...
