Totally fried an IC today. I accidentally put it backwards on my breadboard, and while debugging (because it obviously didn't work) I noticed a funny smell, and then noticed the backwards IC. I cut the power and tried to pull the IC out, and then promptly screamed out loud because that sucker was molten-lava hot. New smell: burnt IC and human flesh. Not a good combination. I then pulled it out with a pair of pliers only to notice it had gotten so hot it melted the plastic on the breadboard and made a nice mess of molten-plastic streamers all over the place. The odor was not improving.
Just to see I plugged it in the right way, and now I get the desired effect but the output is super, super low. Which I assume is due to damage to the IC. But I always assumed when you cooked an IC that it was just dead- no sound at all. Is it possible to fry an IC and just have the result to be very little output? It was a 4046 for the record.
very possible, if it happened to you. :)
I never thought so before either.
I always thought the silicon was a lot more fragile than the plactic.
its probably pooched, just get a new one.
very distinctive smell, which instantly translates (in my case, anyhow) to "uh oh,what did I screwed up???"
m.
That chip might be a resistor now...
...or an ornament.
it's not much of a story without pictures (:
no advice for you though... sorry.
I figured it was toast, I was just surprised it passed any signal at all. ;)

The odor made its way to Fowlerville...

Fowlerville, eh? I've stopped at the gigantic, blue-roofed, gas station/restaurant on numerous trips to Lansing. Assuming you're talking about fowlerville, MI.
i find that most of the time when i've stuffed something up, if i really crank the amp hard enough i can hear my signal coming through. maybe it's compressed or tinny, but it's a bit of confidence for me (:
