Some op amps and other devices say they have an absolutely maximum voltage range of 40V(+- 20V). If I were to run these off 4 9.6V batteries in series or 3 12V batteries in series will it be a bad idea since it may exceed the spec? Can these devices generally run a bit higher without harm? 40V is just right around the standard 3*12 or
4*9.6 except that the maximum voltage of these may actually end up exceeding the 40V by a few volts.Is "absolute maximum" something we shouldn't get close to or something we can design up to and even go over slightly(10% maybe) without worrying too much more about the device failing?
