You cant, it is fixed for any specific supply voltage.
If you want maximum output swing, use CMOS with rail-to-rail outputs.

The AD8532's 250mA output capability is impressive, but its 2.7 to 6V total recommended operating-voltage range is rather limited, even if it does meet the OP's requirement and is fairly low cost (64 cents, DigiKey qty 100). For a jelly-bean recommendation (implies second- source and long product life) I'd prefer a general-purpose part that can handle higher 16V supply voltages, like the TLC272 or LMC6482. One other issue, the AD8532 has a rather high offset-voltage spec, 25mV vs. 10 and 3mV maximum for the other two parts. That may not be much of a problem for a LCD or headphone driver, but...

Unless you have to use the lowest possible cost amp, I would suggest you look at something made for such applications, like:

What is best design practice for maximizing output swing on one amp of the LM358?
Any specific recommendations would be appreciated. Supply is 6V. Input frequency 60 Hz. Load 20mA.
Would a slightly better specified (low power) replacement, such as a TL062, improve prospects in this regard?
Or is there a better choice in this price/performance category.
