1. Guaranteed by design, not tested in production.

2. The saturation voltage can also be limited by the I

load

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.
