See the section for the offset voltage vs. supply. Typical Performance Characteristics
2
The input stage uses PNP transistors; therefore, input bias current always flows out of the part.
3
For G > 1, errors from External Resistor R1 and External Resistor R2 should be considered in addition to these specifications, including error from FB pin bias current.
