In the datasheet it is said only about the maximum and minimum voltage when applied X current, however, I need something more precise to apply in the switching of a load cell.

Is there any formula for calculating the voltage drop with X current at an output? A graphic on this in the datasheet, detailing the voltage drop X current would be interesting!

The precise behaviour of these specs is really dependent on a lot of factors: voltage supply, temperature, current used in other I/Os, general chip current draw, exact silicon batch, age of the chip, current mood of the transistors, phase of the moon, ... As such, we can't give you an exact value for this specification, only the range in which it will fall. If you need something with a well-defined characteristic, I'd suggest setting something up with e.g. an external mosfet and a resistor.
