Tool/software:
Hello,
So the datasheet says the part can survive an indefinite short (to ground), but I'm trying to understand if this is true over the entire temperature range?
Near 150°C, the part can still sink about 25mA when output is shorted.
Lets say that my supplies are +/-15V.
So near 150°C, if the amplifier is trying to drive a negative output voltage and the output is then shorted, the part's power dissipation is 225mW. Certainly, this will push the junction over 150°C (ignoring quiescent power dissipation)? Am I missing something?
Thanks.
