1. See Input offset voltage drift over the temperature in application information.

2. Current is positive when it is sinked into the op-amp.

3. Iio is defined as |Iibp – Iibn|.

4. For higher capacitive values see Figure 23. Phase margin vs. output current at VCC = 5 V and Figure 25. Phase margin vs.

capacitive load

5. Theoretical value of the input current noise density based on the measurement of the input transistor base current:
