A great many clever, useful, and tempting circuit applications have been published. But all too often, in one’s haste to assemble a circuit, some very basic issue is overlooked that leads to the circuit not functioning as expected―or perhaps at all. This article will discuss a few of the most common application problems and suggest practical solutions. 01".1 ' 3 m74 7065 3 %&4*(/&26"5*0/4 mE#*/165#83$ 3*45:1*$"--:4&5&26"-50 5)&1"3"--&-$0.#*/"5*0/ ……
