I am finding the term rail to rail output voltage in opamp what exactly is this in simple but accurate terms.

Most opamps have darlington ordinary transistors as emitter-followers at the output that never saturate (the emitter follows the base with a 0.75V voltage drop and a darlington is two transistors with two base-emitter voltage drops). Therefore the maximum output high is about 1.5V less than the supply voltage and the minimum output low is about +1.5V when there is no load.in simple terms can I say that when opamp reaches saturation it cannot reach to supply voltage but little less.
