Hope this isn't posted already. Wampler does a little demo here that I thought some may find interesting....particularly those who are technically oriented or just want to see how OP Amp circuits are used to a certain degree. Inthis case, the 4558 Dual Op Amp in particular. It may also dispel some myths that people like to throw around on the Internet. I absolutely HATED the OP AMPS course I had to take in Electronics Engineering Tech at NAIT back in the mid 90's...was too damn hard to understand at the time. Or maybe it was just the context the teacher was using to get his point across. Probably the latter actually. Anyways, here it is. Any comments from the usual tech suspects?
