1. See Section 4.4: Input offset voltage drift over temperature.
2. Typical value is based on the V_io drift observed after 1000h 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 Section 4.5:
Long-term input offset voltage drift.
3. Guaranteed by characterization.
4. Slew rate value is calculated as the average between positive and negative slew rates.
5. Initialization time is defined as the delay after power-up which guarantees operation within specified performances.
Guaranteed by design. See Section 4.6: Initialization time.
