[sdiy] 2164 overvoltage condition?

[Sean Ellis]

I've been breadboarding a filter and oscillator using a single 2164 and I think I just fried my only 2164 on hand. I have the power supply protected but accidentally put -12 straight into the input of one amp (the control pin was at about 2.5V) and suddenly it died. The datasheet specifies the max ratings to the supply rails so I don't get why it could have (seemingly) destroyed the chip. Could it maybe have caused excessive heat?
