I am looking at LM6132 specifically. In the datasheet, the absolute maximum "Current at Output Pin" is +-25mA. Yet Digikey lists it's "Current – Output / Channel" as 4mA…
I assume digikey's value is the "recommended" output current.
The amp will be running off a +-12v power supply and unfortunately, in the section for 24v Vcc, the datasheet has no output current figure…
I am just curious as to what impacts I can expect with regard to life expectancy, if any, running the op amp at 10mA roughly 50% of it's life. That is, the opamp will likely be sourcing 10mA half the time it is powered on and 0mA the rest of the time.

Absolute maximum is the minimum of what might be expected to damage a device.
Recommended operation conditions is when the device will work as specified.
In between, the device might not be damaged but it might not work as well as you expect it to (or might not work the way you expect it to which is considerably worse).
In your scenario example, excessive voltage output droop is to be expected, and probably other things like linearity, etc. Not to mention heat.
