Initialization time(6)

T = 25 °C

-40 °C < T< 125 °C

1. See Section 4.4: Input offset voltage drift over temperature.

2. Typical value is based on the Vio 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. Tested on SC70-5 package.

5. Slew rate value is calculated as the average between positive and negative slew rates.

6. Initialization time is defined as the delay after power-up to guarantee operation within specified performances. Guaranteed

by design. See Section 4.6: Initialization time.
