Hello,
I was playing with an op-amp in lab and I think I exceeded the negative power supply voltage maximum. When I applied -6 V, as an example, I noticed the output started to oscillate like crazy.
In regards to the op-amp circuitry, what is going on inside? As soon as I back off the voltage, the output stabilizes again. I just need a simple picture to help visualize what is going on. Suppose I kept driving it more and more negative, trying to reach destructive failure. What is usually the first thing to breakdown internally? What would I expect to see the scope?
Thanks!
