Op amps with load impedance matching
No (not for what you want to achieve)
The datasheet lists HRout (headroom to either supply) which is 1.5V. So max. output voltage will be 28V - 2*1.5V = 25V. But you need to watch out for the output impedance which is 0.17 Ohms. So if your load resistor is e.g. 0.17V, you will get less than 25V/2=12.5V at the output.
No, but it would be correct if this amp had an output impedance of 50 ohms.
