/blogs_/archives/b/precisionhub/posts/op-amp-supply-limits-are-they-criticalA few years ago, a customer asked me a rather surprising question: &ldquo;I realize I am exceeding the maximum supply-voltage rating, but how long will your OPA373 operational amplifier continue to operate if it is powered by a 12V supply?&rdquo; The...en-USTelligent Community 13https://e2e.ti.com/blogs_/archives/b/precisionhub/posts/op-amp-supply-limits-are-they-criticalThu, 19 May 2016 11:14:18 GMTcb01d8b2-d089-468d-babb-77d1d8683490:8585ab79-4b7d-476e-875d-7b47d21737b9Bob Turner0<p>Not forgetting the graph in figure 1 should also extend to negative voltages, &nbsp;plug in a LM324 (or pretty much any quad) backwards, and they get very warm, and the supply gets dragged down to ~0.7v, &nbsp;in many cases the opamp still works afterwards.
