1. See Input offset voltage drift over the temperature in application information.
2. Typical value is based on the VIO drift observed after 1000 h at 125 °C extrapolated to 25 °C using the Arrhenius law and
assuming an activation energy of 0.7 eV. The operational amplifier is aged in follower mode configuration. See Long term
input offset voltage drift.
3. Current is positive when it is sinked into the op-amp.
4. Iio is defined as |Iibp – Iibn|
5. For higher capacitive values see Figure 24. Phase margin vs. output current at VCC = 36 V and Figure 25. Phase margin vs.
capacitive load
6. Theoretical value of the input current noise density based on the measurement of the input transistor base current:
