The 741 chip has been around for many years. Many newer op amps still have this same pinout.

Power supply +12 Volts and -12 Volts is typical. A power supply of +5 Volts and -5 Volts is about the lowest useable supply. Higher voltages can be used for driving power amplifier output MOSFETS.

The maximum output voltage can never be greater than the power supply voltage.

The maximum output voltage from an Ideal Op' Amp' would be equal to the power supply voltage.

The maximum output voltage from a typical Op' Amp' would be up to two volts less than the power supply voltage.

Saturation: This occurs when the Op' Amp' is attempting to generate an output greater than the power supply voltage. When it fails to do this, the output saturates and the distortion results. This is called clipping or limiting.
