1. Guaranteed by design.

2. The saturation voltage can also be limited by the ILOAD (drive current).

3. R2 is the internal resistance between OPAMP output and OPAMP inverting input.

R1 is the internal resistance between OPAMP inverting input and ground.

The PGA gain =1+R2/R1

4. Mostly TTa I/O leakage, when used in analog mode.
