Hello,
I've been doing electronics for a while now, and only recently started using ICs. I have no problem with the 555 timer (I've used it in several circuits), but recently found and attempted the construction of a few circuits with the LM358 op-amp. On each there were two triangles, which I know represented the ICs. But when I saw an image of the circuit, I could only see one chip. I also noticed that none of the pins are repeated. Are both triangles one actual chip? Are the two triangles just ways to represent a single, physical chip?
Here's the circuit I was constructing.
