Opamp Power Supply Connexions
Capricious or logical?
What can go wrong when fitting a component on a circuit board? All sorts of things of course, but in this case the cause turned out to be really strange: The power supply connections of the IC were in the wrong place!During the testing of the first prototype of the Tabula Tangibles (a project that is a collaboration between Elektor Labs and Aachen Technical University), there was something seriously amiss with the power supply: the output of the voltage regulator appeared to be short-circuited.
